Python - pip install pandas, not working - python

I am trying to install pandas via pip install pandas but when I do, I get the error:
Command python setup.py egg_info failed with error code 1 in
c:\users[username]\appdata\local\temp\pip_build_[username]\pandas
I followed the answer given here and installed ez_setup.py without incident, but still get the error when doing pip install pandas.
Thanks for any help, if I can provide more information please let me know.

The easiest way to install pandas and its dependencies on Windows is to download the relevant packages from Christoph Gohlke's Python Extension Packages for Windows repository. You'll find the files for pandas here as well as a list of other required dependencies.

On Linux (Debian / Ubuntu varieties), when NOT installing inside a virtual environment, but in the main system, I find it best to just use the Synaptic Package Manager (because even the --user switch seems to fail when trying to install pandas without sudo). Search for pandas inside Synaptic PM. There's varieties for python 2 and 3.
However, on linux, I have generally found the cleanest, easiest, and overall safest approach to be creating virtual environments and then use pip install <package name> inside the virtual environment. I believe this would be best on Windows too.

I installed Pandas package following procedure listed after the following disclaimer section:
Disclaimer:
- I don't consider myself a computer expert so follow the instructions at your own risk.
- My procedure worked on my windows computer
- My windows computer has python 2.7 installed from python.org
- My python GUI is IDLE
- I don't recall installing pip, it is possible that it installs at the time of installing python 2.7 from python.org (not sure)
- The directory in which my pip.exe is located is under C:\Python27\Scripts
Procedure:
Open a command window for the directory under which you have pip.exe, (in my case is Scripts). The prompt looks like this in my case: C:\Python27\Scripts>
At the prompt type pip install pandas. The prompt looks like this in my case: C:\Python27\Scripts>pip install pandas
Press ENTER key. You should see message: "Collecting pandas" being displayed in the command window.
Once the system completes collecting pandas, you should see message "Successfully installed pandas-0.22.0" , or similar depending on version collected.
Picture shows steps 1 -4 as shown in my computer command window.collecting_pandas

Should Which Pip and Which Python Return the Same Directory? Zeppelin Configuration On Unix RHEL

This is probably a really dumb question but I am stuck and wasting too much time on this so I would SO appreciate any help.
I am using a RHEL 7 box and installed Apache Zeppelin on it. Everything works except for the life of me I can't import Python packages such as Pandas.
I realized I didn't have PIP so I installed it with these steps: https://pip.pypa.io/en/stable/installing/ (notice I had to use the "--user" argument for the command "python get-pip.py").
Finally, I did "pip install pandas --user" which worked perfectly. I then go into my Zeppelin notebook and I cannot import pandas, even after restarting the Python interpreter.
I did some research and I think the problem is that "which python" and "which pip" are installed in different directories as the former results in "/usr/bin/python" while the latter in "~/.local/bin/pip".
So I suspect the packages installed with pip are basically getting loaded into a different version of python? If it helps, when I do "whereis python" I get 5 different results such as "/usr/bin/python" and "/usr/bin/python2.7" etc.
First thing to understand is: Python packages aren't installed globally, every installed Python has its own set of packages. BTW, pip being a Python package with a script is also not global. If you have a few different pythons you need different pips for them. I don't know Apache Zeppelin so I cannot guess if it uses the system Python (/usr/bin/python) or has its own Python; in the latter case you need to install pip specifically for Zeppelin so its pip install packages available for Zeppelin.
To investigate to what Python pip installs packages you need to find out under what python it runs. Start with shebang:
head -1 `which pip`
The command will prints something like ~/.local/bin/python. If it's not the version of Python you need to install packages for you need to install a different pip using that Python.
The most complex case would be if the shebang is PATH-dependent, something like #!/usr/bin/env python. In that case pip runs Python that you can find with which python.
PS. AFAIK the simplest way to install pip at RedHat is dnf install python-pip.
phd's answer was very helpful but I found that it was just a matter of using the root account to install the python packages. Then my Zeppelin was able to see any packages.

unable to install pymorph

I'm trying to install 'pymorph' on mac os x with 'PIP':
sudo pip install pymorph
I'm getting the following error:
NameError: name 'execfile' is not defined
Command "python setup.py egg_info" failed with error code 1 in
/private/tmp/pip-build-9hjd5tfm/pymorph/
I have read that using a python version different from 2.7 could lead to this kind of problem. Yet, I'm using the 2.7 version:
python --version
Python 2.7.13
Any ideas to solve this issue ?
Thank you in advance
It's possible to have a pip command on your PATH that comes from a different Python installation than the python command. (Each entry script to a Python-based tool is bound to the Python installation that was used to install the package that provided it. This means that the pip command does not search PATH for a python installation.) If this pip comes up later on PATH than python, it would lead to behaviour that you describe.
This can happen, say, if you first install a Python 2.7 without pip, and then a Python 3.x with pip, if the installers prepend to PATH.
You can verify which version of Python pip is using and where it's installed by running pip -V.
The robust solution to this should be using a virtual environment that lets you tie the base python installation and libraries specific to your application alone with your project, as well as avoid cluttering your global site-packages, and prevent inadvertent compatibility issues from different versions of the same package being needed by different projects.
It seems that the current (as of late 2017) recommended virtual environment solution is Pipenv. A decent-looking introduction to virtual environments using Pipenv, by the author of Pipenv, can be found here.

Python 3.5.1 Pygame Installation

I am trying to install Pygame for Python 3.5.1, but it tells me to upgrade to the new version of pip. "You are currently using 7.1.2, use 8.1.2".
Here is a screen shot of it:
The error clearly states Access Denied.
Try to run cmd/powershell as administrator.
The installation error is not because of pip , though you should still upgrade pip
python -m pip install --upgrade pip
Pygame does not have python3.5 support yet. Check the binaries here
Pygame binaries
Try to use Python version 3.4 or 2.7 and then install pygame.
EDIT
You can find unofficial pygame binaries for several Python versions including Python3.5 here.
So if you do not find the official binary, you could try the appropriate file from the above link.
Note: The binaries given there are whl files. So you need to install them using pip.
Example: Assuming you have 32-bit Python installation, run pip install pygame-1.9.2b1-cp35-cp35m-win32.whl
See this answer for more detailed instructions.
Pip seems to be having a permission problem creating this directory: c:\program files (x86)\python35-32\Lib\site-packages\pygame
Here are some things you can try:
Navigate to that directory and see if it already exists. If it does exist, then try deleting it.
Try running pip as an administrator. Right click the command prompt icon and select run as administrator. Your path variables might not be set for the administrator, so you many need to give the full path for pip. In your python folder, it should be in a folder called scripts.
Since you're using Windows, you can also try the binary installers here: http://www.pygame.org/download.shtml
If nothing works you can try installing a different version of Python. I use Python 2.7.8 with pygame.
It was a problem based on the admin command run program and I figures it out.

pycharm interpreter using cygwin version python

I am running django python2.7 using Pycharm in windows.
Now I have some issue with redis queue not working in windows because of this
I am trying to do what this person did here. Use a cygwin version of python as pycharm interpreter.
(not sure if I downloaded all the packages or did correct steps)
I downloaded cygwin and install packages python2.7 + python-setuptools and then try to point my Pycharm interpreter to c:/cygwin/bin/python27.exe
see image
After that it seem ok and ask me to install packing tools pip, I clicked it and it give me this error:
see image
"Cannot start process, the working directory '\cygdrive\c\Users\User1G~1.SIS\AppData\Local\Temp\1\tmpYpudf2pycharm-management\pip-7.1.0' does not exist"
According to the error message it looks like pip can't be found... Are you sure you have installed pip?
Take a look here, how you can install pip: Installing Pip-3.2 on Cygwin
You can open a cygwin command line window and try to manually install the packages you want to.

error in installing matplotlib1.5.1 in python3.5

I have 'Windows 8'. I installed 'python35-32' successfully. Then I download 'matplotlib 1.5.1' . But it can not installed . I get an error that required package can not be built.
Try this:
Open cmd with admin privilege. (right click and Run as administrator)
Enter this command pip install matplotlib, and wait for the installation to complete.
Alternative:
If you want to keep the wheels for offline installation later, you can do the following:
Open cmd, and enter this command
pip install --download /path/to/some/dir/ matplotlib. This will download matplotlib and all other required wheels in the directory /path/to/some/dir/.
To install, enter this command: pip install --no-index --find-links /path/to/some/dir/ matplotlib
Here /path/to/some/dir/ is the directory where the file gets downloaded. You can use . instead of /path/to/some/dir/ to download in the current directory.
Edit:
Take a look at matplotlib installation guide for windows. The line most relevant to your case is probably this:
For Python 3.5 the Visual C++ Redistributable for Visual Studio 2015 needs to be installed.
So just install it by following the link and then follow the above procedure. That should do the trick.
Note: They also suggest that the best option is using one of the pre-packaged python distributions that already provide matplotlib built-in, like Anaconda, miniconda and canopy. You may want take into consideration too.
Edits as per your comment
As I have already said, anaconda is a pre-packaged python distribution that includes hundreds of python packages. To quote the official python page, anaconda is "a full Python distribution for data management, analysis and visualization of large data sets". So you can do pretty much everything with anaconda that you can do with the traditional python (aka CPython), plus you have a great number of popular python packages at your disposal.
To get yourself started with anaconda, you can check this out: Test drive Anaconda.
