Hi guys I found a solution on this problem.
1. Easyest way is to install Visual Studio and all packages for C++ or only the package for Dlib - this should slove the problem.
On this link https://github.com/ageitgey/face_recognition/issues/175#issue-257710508 can be find detail descriprion for installation from "masoudr".
I will put the installation guide bellow:
"Hi,
I've successfully installed and tested this tool on my windows 10 machine and I'm writing a simple procedure to install it. It may be useful for some people try to use this tool on a Windows machine.
IMPORTANT: Actually this project has made for Linux systems and especially dlib. In my tests, the performance of this tool in Windows 10 was about a quarter in comparison with Ubuntu built with the same specs. But I haven't seen any difference between these two in other subjects.
Read First:
The new version of dlib doesn't need Boost anymore so you can skip it. Remember that you still need to meet the following requirements.
Requirments:
(I've used this tutorial with these tools installed on Windows 10 but the newer versions may work too.)
Microsoft Visual Studio 2015 (or newer) with C/C++ Compiler installed. (Visual C++ 2015 Build Tools didn't work for me and I got into problems in compiling dlib)
Boost library version 1.63 or newer. Also, you can use precompiled binaries for specific MSVC you have but I don't suggest. (I've included the compiling procedure of Boost in this tutorial)
Of course Python3 (I used Python3.5 x64 but the other versions may work too)
CMake for windows and add it to your system environment variables.
Installation:
Easy installation:
Just install dlib and face_recognition (not always on newest version):
pip install dlib and then pip install face_recognition.
Manual installation:
Download and install scipy and numpy+mkl (must be mkl version) packages from this link (all credits goes to Christoph Gohlke). Remember to grab the correct version based on your current Python version.
Download Boost library source code or binary release for your current MSVC from this link.
If you downloaded the binary version skip to step 4 else follow these steps to compile and build Boost by yourself:
3-1. Extract the Boost source files into C:\local\boost_1_XX_X (X means the current version of Boost you have)
3-2. Create a system variable with these parameters:
Name: VS140COMNTOOLS
Value: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\ (or any path where you have installed MSVC)
3-3. Open Developer Command Prompt for Visual Studio and go to the current directory of Boost extracted and try these commands to compile Boost:
bootstrap
b2 -a --with-python address-model=64 toolset=msvc runtime-link=static
3-4. If you successfully compile Boost, it should create compiled files in stage directory.
(If you have already compiled Boost skip this step) If you already download the binary release just extract the contents to C:\local\boost_1_XX_X
Grab latest version of dlib from this repo and extract it.
Go to dlib directory and open cmd and follow these commands to build dlib: (remember to replace XX with the current version of Boost you have)
set BOOST_ROOT=C:\local\boost_X_XX_X
set BOOST_LIBRARYDIR=C:\local\boost_X_XX_X\stage\lib
python setup.py install --yes USE_AVX_INSTRUCTIONS or python setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA
Now you can use import dlib without any problem in your python script.
You can also check the current version of dlib with pip show dlib.
Now simply install face_recognition with pip install face_recognition.
Enjoy!
Finally, I need to say thanks to #ageitgey and #davisking for their awesome work."

Errors installing Netfaces for Python in Win10 [duplicate]

I just ran the following command:
pip install -U steem
and the installation worked well until it failed to install pycrypto.
Afterwards I did the
pip install cryptography
command because I thought it was the missing package.
So my question is, how I can install steem without the pycrypto-error (or the pycrypto-package in addition) and how to uninstall the cryptography-Package which I don't need.
(I'm using Windows 7 and Python 3)

You need to install Microsoft Visual C++ 14.0 to install pycrypto:
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
In the comments you ask which link to use. Use the link to Visual C++ 2015 Build Tools. That will install Visual C++ 14.0 without installing Visual Studio.
Alternate link: https://wiki.python.org/moin/WindowsCompilers#Microsoft_Visual_C.2B-.2B-_14.2_standalone:_Build_Tools_for_Visual_Studio_2019_.28x86.2C_x64.2C_ARM.2C_ARM64.29
In the comments you ask about methods of installing pycrypto that do not require installing a compiler. The binaries in the links appear to be for earlier versions of Python than you are using. One link is to a binary in a DropBox account.
I do not recommend downloading binary versions of cryptography libraries provided by third parties. The only way to guarantee that you are getting a version of pycrypto that is compatible with your version of Python and has not been built with any backdoors is to build it from the source.
After you have installed Visual C++, just re-run the original command:
pip install -U steem
To find out what the various install options mean, run this command:
pip help install
The help for the -U option says
-U, --upgrade Upgrade all specified packages to the newest available
version. The handling of dependencies depends on the
upgrade-strategy used.
If you do not already have the steem library installed, you can run the command without the -U option.

If you already have Visual Studio Build Tools installed but you're still getting that error, then you may need to "Modify" your installation to include the Visual C++ build tools.
To do that:
Open up the Visual Studio Installer (you can search for it in the Start Menu if needed).
Find Visual Studio Build Tools and click "Modify":
Add a checkmark to Visual C++ build tools and then click "Modify" in the bottom right to install them:
After the C++ tools finish installing, run the pip command again and it should work.

I got this error when I tried to install pymssql even though Visual C++ 2015 (14.0) is installed in my system.
I resolved this error by downloading the .whl file of pymssql from here.
Once downloaded, it can be installed by the following command :
pip install python_package.whl
Hope this helps

I landed on this question after searching for "Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools". I got this error in Azure DevOps when trying to run pip install to build my own Python package from a source distribution that had C++ extensions. In the end all I had to do was upgrade setuptools before calling pip install:
pip install --upgrade setuptools
So the advice here about updating setuptools when installing from source archives is right after all:). That advice is given here too.

As an alternative to installing Visual C++, there is a way by installing an additional package in Conda (this option doesn't require admin rights). This worked for me:
conda install libpython m2w64-toolchain -c msys2

I faced the same problem. Found the fix here.
Basically just install this.
shasum output:
3e0de8af516c15547602977db939d8c2e44fcc0b visualcppbuildtools_full.exe
md5sum output:
MD5 (visualcppbuildtools_full.exe) = 8d4afd3b226babecaa4effb10d69eb2e
Run your pip installation command again. If everything works fine, its good. Or you might face the following error like me:
Finished generating code
LINK : fatal error LNK1158: cannot run 'rc.exe'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe' failed with exit status 1158
Found the fix for the above problem here:
Visual Studio can't build due to rc.exe
That basically says
Add this to your PATH environment variables:
C:\Program Files (x86)\Windows Kits\8.1\bin\x86
Copy these files:
rc.exe
rcdll.dll
From
C:\Program Files (x86)\Windows Kits\8.1\bin\x86
To
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin
It works like a charm

Pycrypto has vulnerabilities assigned the CVE-2013-7459 number, and the repo hasn't accept PRs since June 23, 2014.
Pycryptodome is a drop-in replacement for the PyCrypto library, which exposes almost the same API as the old PyCrypto, see Compatibility with PyCrypto.
If you haven't install pycrypto yet, you can use pip install pycryptodome to install pycryptodome in which you won't get Microsoft Visual C++ 14.0 issue.

Updated link here for download Microsoft Visual C++ 14.0
Download
It works for me without a Visual Studio downloader

On Windows, I strongly recommand installing the latest version of Visual Studio Community. It's free, you will maybe miss some build tools if you only install vc_redist, so you can easily install package by pip instead of wheel, it save lot of time.

Try doing this:
py -m pip install pipwin
py -m pipwin install PyAudio

Three steps I follow for this error:
C++ Build tools are installed
pip install --upgrade setuptools
try using conda to install, conda may have the compiled version which won't need the build tools

None of the solutions proposed by other people here worked for me.
So in my case I had to uinstall ALL older versions
of Microsoft Visual C++ Redistributable from my computer:
Only the newest one (in my case 2015-2022) should be left!
After uinstalling I ran this command:
pip install <your_lib_name>
and everything worked great after that.

Killer solution: install nodejs and tick the option of install chocolatey and other necessary tools... and it will install the tools required to setup a development environment.

Installing NumPy on Windows is a common problem if you don't have the right build setup. Instead, I always go to Christoph Gohlke's website to download the wheels you can install for your computer. Christoph generously builds the libraries himself with the right build environment and he posts it on his website.
Newer Instructions - For older instructions, please scroll down
First, install pipwin from PyPI which will install a utility that acts like pip but it will download the actual package you're interested in from his website, then use pipwin install to install the package you want.
First do:
pip install pipwin
When that's installed, you can then do:
pipwin install numpy
This will install the latest version of NumPy on your system. This way you don't have to specifically search for the version of NumPy that is for your specific version of Python.
Older instructions
Go to the NumPy section: https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy then download the version for 3.7 that is compatible with your version of Python (2 or 3 and 32-bit or 64-bit). For example, the filename numpy‑1.14.5+mkl‑cp37‑cp37m‑win_amd64.whl is for NumPy 1.14.5, Python 3.7 - 64 bit. You can pick out which version of NumPy and which version of the Python interpreter and bit version you need in the filename.
Doing this never requires you to build NumPy yourself or install the required compiler as opposed to installing NumPy through PyPI. You can just download the wheel and install it yourself. Assuming you've already downloaded it, just do:
pip install numpy‑1.14.5+mkl‑cp37‑cp37m‑win_amd64.whl
... assuming the wheel is in the directory you're currently in.

Starting 24 November 2021, latest numpy require at least Python 3.8
Note: This might not be the original question asked, but it might help anyone come here.
To use python 3.7, latest numpy you can use is v1.21.4. So, to install it, use:
pip install numpy==1.21.4
If you write requirements that you hope compatible with python 3.7, you can use numpy<=1.21.4
EDIT: in 20 December 2021, numpy release version 1.21.5 that support Python 3.7
From comment section, by #sam, numpy 1.21.5 support Python 3.7. It was released after 1.22.0rc1 (the latest numpy version as the writing of the original post) that only support Python 3.8++.
Lesson learned from this experience, it would be better to use <,
pip install numpy<1.22.0
or
install_requires = [
"numpy<1.22.0", # lates version to support python 3.7
],

For windows when you install a package you type in Python 3:
py -m pip install [packagename]
OR
py -m pip install numpy

You're probably missing a C compiler. If numpy doesn't provide a prebuilt wheel yet, you'll need to install a compiler. This website shows the one you need to install. For 3.7, I assume it's still 14.0, so you should install Microsoft Build Tools for Visual Studio 2017.
Let me know if that works.

Thanks.

Here is what works for me...
Download TA_Lib-0.4.10-cp27-cp27m-win_amd64.whl from here
And use command pip install TA_Lib-0.4.10-cp27-cp27m-win_amd64.whl
I was using Conda4 with python 3.6 64 bit version.
Another way also you can try
To install Ta-Lib with Python 3.6+, Windows 64 bit use this pip install -i https://pypi.anaconda.org/masdeseiscaracteres/simple ta-lib

The root cause of the error is probably because you haven't installed actual TA-Lib library which is written in C. Note that the python lib is just a wrapper on top of the actual library. So in order to have python wrapper successfully installed, you'll need to install its prerequisite (the actual TA-Lib).
See https://github.com/mrjbq7/ta-lib#dependencies for more details.
From above reference (for ease of access) :
Installing actual TA-Lib (prerequisite for python wrapper) :
Windows
Download ta-lib-0.4.0-msvc.zip and unzip to C:\ta-lib
Move the Unzipped Folder ta-lib to C:\
Download and Install Visual Studio Community 2015 if already not installed (Remember to Select [Visual C++] Feature)
open x64 Native Tools Command Prompt
navigate to C:\ta-lib\c\make\cdr\win32\msvc
type nmake (this command builds the library)
Linux
$ tar -xzf ta-lib-0.4.0-src.tar.gz
$ cd ta-lib/
$ ./configure --prefix=/usr
$ make
$ sudo make install
Mac OS X
$ brew install ta-lib
If you are using a M1 laptop and Homebrew, then you can set these before installing:
export TA_INCLUDE_PATH="$(brew --prefix ta-lib)/include"
export TA_LIBRARY_PATH="$(brew --prefix ta-lib)/lib"
Hint : It seems, by default, the setup.py reads actual library files from C:\ta-lib (in Windows) and /usr (in Linux). so if you move the downloaded zip file to another location and extract it there (for Windows) or set ./configure --prefix to any location other than /usr (for Linux), then you would have to set TA_LIBRARY_PATH and TA_INCLUDE_PATH environment variables to your desired locations.
If you installed the underlying TA-Lib library with a custom prefix (e.g., with ./configure --prefix=$PREFIX), then when you go to install this python wrapper you can specify additional search paths to find the library and include files for the underlying TA-Lib library using the TA_LIBRARY_PATH and TA_INCLUDE_PATH environment variables:
$ export TA_LIBRARY_PATH=$PREFIX/lib
$ export TA_INCLUDE_PATH=$PREFIX/include
$ python setup.py install # or pip install ta-lib

The documentation of Ta-lib package here is well clear:
https://github.com/mrjbq7/ta-lib
https://mrjbq7.github.io/ta-lib/
And as it was clearly mentionned! this python ta-lib library! Is a wrapper for the TaLib library at https://ta-lib.org/
This is a Python wrapper for TA-LIB based on Cython instead of SWIG
To know the ta-lib.org library is a library created in c lang! You can check here
And multiple binding and interfaces are made for different languages! Just as mentionned in the official website!
The python library is a binding for python that use cython! Which make it more efficient then SWIG!
Know that I'll insist on using pip! (it works all well and it's convenient)
For the installation to go well! You'll need to go in two steps! You need to install TaLib native library binaries first! Then install the python lib with pip (again with pip)! And this order is necessary! You can't go for installing the python binding before the first installation finish!
All that said!
Installation
Step 1: Installing Talib native binary
Installing the Ta-lib software (Or native library binary)! Is a must! And need to be done first!
Follow the instructions here:
https://github.com/mrjbq7/ta-lib#dependencies
The instructions are too clear and detailed!
(Linux users you need to execute the command with the right privelege (hince using sudo))
And last thing! You can check #Code_Worm answer in this thread here He explained many points highly well aboutt the instruction above !
I'll pin point too his hint:
Hint : It seems, by default, the setup.py reads actual library files from C:\ta-lib (in Windows) and /usr (in Linux). so if you move the downloaded zip file to another location and extract it there (for Windows) or set ./configure --prefix to any location other than /usr (for Linux), then you would have to set TA_LIBRARY_PATH and TA_INCLUDE_PATH environment variables to your desired locations.
Check the section bellow this hint!
You can check the trouble shooting section here
Step 2: Installing the python library using pip
Don't proceed with this step until the first step is successfully finished and done with!
Again the pip package and pip works well! And so no need to use some whl file from any other website and src! I'll show you how!
pip install TA-Lib
However here there is many things to say!
First you need to use python 3
So you may use pip3 instead of pip! If pip is resolving to the python2 version (which is common in linux installations)!
pip3 install TA-Lib
Now you may fall in this problem and error!
unescape = getattr(html, 'unescape', html_parser.HTMLParser().unescape)
AttributeError: 'HTMLParser' object has no attribute 'unescape'
IF such is the case! That's a problem that can come with python 3.9! (if you are using 3.8 you may not encounter that at all)!
The solution and fix is simple! We have just to make an upgrade to some packages! You can follow the instructions from the answer here:
https://stackoverflow.com/a/65640477/7668448
After some trial and error I upgraded, pip, distlib and setuptools and it solved it. Not sure which of those is causing it. (On the last two I found issues 1 2 of other sites)
It is caused by removing unescape from HTMLParser in python3.9, which seems to break setuptools.
pip3 install --upgrade setuptools
If it does not work, try also:
pip3 install --upgrade pip
pip3 install --upgrade distlib
That's it all! If the first step (step 1: Installing TaLib native binaries) is well done and finished! Then running pip3 install TA-Lib will works well this time!
For Linux users! If you run it with sudo! And it failed! Don't use sudo! You should not!
For linux users you may need to install python headers
sudo apt-get install python3-dev
You can try it only if it didn't works! In most linux distro! You'll be ok by default!
Last (Trouble shooting doc section)
If needed Check the trouble shooting section here

If you didn't installed first TA-lib native library (as mentioned here and installed python ta-lib first it helps to re-install TA-lib using: pip install --upgrade --force-reinstall TA-lib

i would suggest installing using the wheel from here. Recently i ran across the same problems while trying to upgrade the library which is again another thing you wouldn't want to do.
Hope this helps. Good luck.

Pip error: Microsoft Visual C++ 14.0 is required

I just ran the following command:
pip install -U steem
and the installation worked well until it failed to install pycrypto.
Afterwards I did the
pip install cryptography
command because I thought it was the missing package.
So my question is, how I can install steem without the pycrypto-error (or the pycrypto-package in addition) and how to uninstall the cryptography-Package which I don't need.
(I'm using Windows 7 and Python 3)

You need to install Microsoft Visual C++ 14.0 to install pycrypto:
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
In the comments you ask which link to use. Use the link to Visual C++ 2015 Build Tools. That will install Visual C++ 14.0 without installing Visual Studio.
Alternate link: https://wiki.python.org/moin/WindowsCompilers#Microsoft_Visual_C.2B-.2B-_14.2_standalone:_Build_Tools_for_Visual_Studio_2019_.28x86.2C_x64.2C_ARM.2C_ARM64.29
In the comments you ask about methods of installing pycrypto that do not require installing a compiler. The binaries in the links appear to be for earlier versions of Python than you are using. One link is to a binary in a DropBox account.
I do not recommend downloading binary versions of cryptography libraries provided by third parties. The only way to guarantee that you are getting a version of pycrypto that is compatible with your version of Python and has not been built with any backdoors is to build it from the source.
After you have installed Visual C++, just re-run the original command:
pip install -U steem
To find out what the various install options mean, run this command:
pip help install
The help for the -U option says
-U, --upgrade Upgrade all specified packages to the newest available
version. The handling of dependencies depends on the
upgrade-strategy used.
If you do not already have the steem library installed, you can run the command without the -U option.

If you already have Visual Studio Build Tools installed but you're still getting that error, then you may need to "Modify" your installation to include the Visual C++ build tools.
To do that:
Open up the Visual Studio Installer (you can search for it in the Start Menu if needed).
Find Visual Studio Build Tools and click "Modify":
Add a checkmark to Visual C++ build tools and then click "Modify" in the bottom right to install them:
After the C++ tools finish installing, run the pip command again and it should work.

I got this error when I tried to install pymssql even though Visual C++ 2015 (14.0) is installed in my system.
I resolved this error by downloading the .whl file of pymssql from here.
Once downloaded, it can be installed by the following command :
pip install python_package.whl
Hope this helps

I landed on this question after searching for "Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools". I got this error in Azure DevOps when trying to run pip install to build my own Python package from a source distribution that had C++ extensions. In the end all I had to do was upgrade setuptools before calling pip install:
pip install --upgrade setuptools
So the advice here about updating setuptools when installing from source archives is right after all:). That advice is given here too.

As an alternative to installing Visual C++, there is a way by installing an additional package in Conda (this option doesn't require admin rights). This worked for me:
conda install libpython m2w64-toolchain -c msys2

I faced the same problem. Found the fix here.
Basically just install this.
shasum output:
3e0de8af516c15547602977db939d8c2e44fcc0b visualcppbuildtools_full.exe
md5sum output:
MD5 (visualcppbuildtools_full.exe) = 8d4afd3b226babecaa4effb10d69eb2e
Run your pip installation command again. If everything works fine, its good. Or you might face the following error like me:
Finished generating code
LINK : fatal error LNK1158: cannot run 'rc.exe'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe' failed with exit status 1158
Found the fix for the above problem here:
Visual Studio can't build due to rc.exe
That basically says
Add this to your PATH environment variables:
C:\Program Files (x86)\Windows Kits\8.1\bin\x86
Copy these files:
rc.exe
rcdll.dll
From
C:\Program Files (x86)\Windows Kits\8.1\bin\x86
To
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin
It works like a charm

Pycrypto has vulnerabilities assigned the CVE-2013-7459 number, and the repo hasn't accept PRs since June 23, 2014.
Pycryptodome is a drop-in replacement for the PyCrypto library, which exposes almost the same API as the old PyCrypto, see Compatibility with PyCrypto.
If you haven't install pycrypto yet, you can use pip install pycryptodome to install pycryptodome in which you won't get Microsoft Visual C++ 14.0 issue.

Updated link here for download Microsoft Visual C++ 14.0
Download
It works for me without a Visual Studio downloader

On Windows, I strongly recommand installing the latest version of Visual Studio Community. It's free, you will maybe miss some build tools if you only install vc_redist, so you can easily install package by pip instead of wheel, it save lot of time.

Try doing this:
py -m pip install pipwin
py -m pipwin install PyAudio

Three steps I follow for this error:
C++ Build tools are installed
pip install --upgrade setuptools
try using conda to install, conda may have the compiled version which won't need the build tools

None of the solutions proposed by other people here worked for me.
So in my case I had to uinstall ALL older versions
of Microsoft Visual C++ Redistributable from my computer:
Only the newest one (in my case 2015-2022) should be left!
After uinstalling I ran this command:
pip install <your_lib_name>
and everything worked great after that.

Killer solution: install nodejs and tick the option of install chocolatey and other necessary tools... and it will install the tools required to setup a development environment.

Error while installing Scrapy error: Microsoft Visual C++ 14.0 is required

I found about scrapy that is a great tool scraping so i tried to install scrapy on my machine, but when i tried to do pip install scrapy it installed for a while and threw me this error..
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
I tried to install it in virtual environment but still the problem persists.
EDIT:
here is what i got after the error..
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

any help?

Install Using Conda
If you have conda Use: conda install -c anaconda scrapy
Or
Install Using pip
Download https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted at this location
//Download the whl file of same version as Python version here cp27 means python2.7
pip install Twisted-18.9.0-cp27-cp27m-win_amd64.whl
pip install scrapy

UPDATE
As some one pointed out in the edit, if you download only the vc_redist.x64.exe it's just 15MB, for that go to "other tools and frameworks" and choose MS Visual C++
solved the problem by installing the tools from here
the thing is that some python modules require C++ tools to compile with a python wrapper around, as they are written in C++.
once the setup is downloaded you can select the specific tools or download other facilities provided.
it's somewhere around 4 GB but solves the purpose if in future you need to use some other module which are made in C++.

but the question is what does scrapy has to do with visual studio
Some python modules require a C/C++ compiler to build. That's why you need Visual Studio.
Quoting from Scrapy Installation Guide:
some binary packages that Scrapy depends on (like Twisted, lxml and
pyOpenSSL) require a compiler available to install, and fail if you
don’t have Visual Studio installed.

I have just installed the Visual Studio desktop tools for C++ and solve it.

Install and use anaconda (A Python packages manager) instead of pip.
Download anaconda from here then use:
conda install scrapy

You have to install Python 2.7 then you have to put Python27 and Pyhton27/Scripts on path and install Visual C++ 14 or above and type pip install Scrapy in your cmd.

Installing only the "vc_redist.x64.exe" didn't work for me.
I downloaded Visual Studio 2019 Community here and then chose "C++ desktop developement" and then only the first two boxes (see the following screenshot ont the right):
This worked for me.

Just installed visual studio build tools and the problem get solved. Happy coding!
