Python installation in Windows 10 - python

I tried to install Python 3.7.6 in windows 10. All went well until when in the cmd prompt of the computer as soon as I entered python to check the cmd prompt took me to microsoft app store and asked me to download python 3.7.7. It is not recognizing the python 3.7.6 that I had downloaded. Can any one help me with this

it's just a case, i encountered the similar problem just download the app to get rid of the redirect to the store and it will be all ok.

Yeah i have experienced the same issue .
But i have found an alternative solution to this problem.
Download Anaconda and then type "conda install python 3.7.6" in the anaconda prompt or u can also create a custom environment by typing "conda create -n py376 python=3.7.6 anaconda" in the anaconda prompt and then u shall see the version of python installed on ur environment by typing "python --version"

After Anaconda installation, python gets recognized in cmd launched by Anaconda Navigator only - Does it mean python can be used within Anaconda?

Learning from this post , I understand that installing Anaconda on Windows 10 PC will automatically install Python compiler, so we don't need to install Python separately after we install Anaconda. Sounds good.
I install Anaconda and then start the Navigator.
Then I launch CMD.exe from Anaconda Navigator and type python --version to check the python compiler installed on my machine. So far so good.
Then I start CMD.exe manually from windows 10 as Administrator (Click Start --> Type CMD manually --> Right Click --> Run as Administrator).
Then I type python --version , it shows "Not Found".
Does it mean that when installing Anaconda , Python is available only within Anaconda platform? Not globally anywhere within the Windows OS ?
This is only an issue of how PATH is set. Note how there is an additional (base) prepended to the C:\>.... prompt. This indicates that a conda environment is currently active, which is what you are currently referring to as being "inside of anaconda". But more correctly, you should think of it like: I have a cmd prompt and the conda base environment is currently active.
When you run cmd from anaconda navigator, this get's done automatically. When you launch it by just starting cmd.exe, then this does not get done automatically. This behaviour could be influenced by checking the Add Anaconda to PATH during the installation.
To get a cmd prompt with the (base) environment active, you can do different things:
Start cmd from your anaconda navigator (as you have done so far)
Start the Anaconda Command Prompt, which you can find through hitting the windows key and then start typing the name
Start a normal cmd and then execute <CONDA Install Dir>\Scripts\activate.bat

Conda activate base error - The term "conda" is not recongised

I'm trying to use anaconda with visual studio code but keep getting this error message every time I try to run something.
enter image description here
enter image description here
What Iv'e tried/confirmed:
Python 3.9.1 is installed and Iv'e got no problems running codes in VSC when I use the standard enviroment or inside a command terminal.
The version of python the anacoanda says it is using is 3.8.5. Should it be 3.9.1 or is that normal?
Python and anaconda were added to path during installation - Iv'e already made that mastake before.
Presumably anaconda is installed properly. I can access the navigator and command prompt.
Its not the code that Iv'e writen. I tried simply writing print("Hello") and it gives me the same error.
Installed the latest version of anaconda.
I have encountered the same problem. The reason is that VS Code uses the powershell terminal by default, but powershell does not activate the conda environment by default.
Therefore, it is recommended that you use the cmd terminal or other terminals that come with the system. (Because in VS Code, the terminal it uses is to integrate the terminal from the system and it not only supports the powershell terminal.)
Solution: for example, switch to using cmd terminal:
Reference: Integrated terminal in VS Code.

Python not recognised in windows prompt cmd

Anconda prompt:
where conda
C:\Users\shail\AppData\Local\Continuum\anaconda3\Library\bin\conda.bat
C:\Users\shail\AppData\Local\Continuum\anaconda3\Scripts\conda.exe
C:\Users\shail\AppData\Local\Continuum\anaconda3\condabin\conda.bat
where python
C:\Users\shail\AppData\Local\Continuum\anaconda3\python.exe
C:\Users\shail\AppData\Local\Microsoft\WindowsApps\python.exe
So i went to environment variables and added path of anaconda and python. Path added:
C:\Users\shail\AppData\Local\Continuum\anaconda3
C:\Users\shail\AppData\Local\Microsoft\WindowsApps
C:\Users\shail\AppData\Local\Continuum\anaconda3\Library\bin
C:\Users\shail\AppData\Local\Continuum\anaconda3\Scripts
C:\Users\shail\AppData\Local\Continuum\anaconda3\condabin
But when I type on windows cmd:
C:\Users\shail>conda --version
conda 4.8.3
C:\Users\shail>python --version
C:\Users\shail>
So there is no response from windows cmd on version of python, so I guess it is not recognising python. I mainly need to use pip command, for that I need python first. I dont have python separately installed on system. It is inside my anaconda. On some sites it is written I should not download python separately and add its path because that will confuse the computer since there will be 2 pythons; one from Anaconda and one downloaded separately. So sticking to the anaconda version of python.
How to get my anaconda version of python recognised ?
pip worked for me after restarting my computer. Though python is still not returning any output but pip is working fine.

Anaconda Installed but Cannot Launch Navigator

Anaconda (listed as "Python 3.6.0 (Anaconda 4.3.1 64 bit)" ) is in my programs and features list, but there is seeming no Anaconda Navigator desktop app, as their seems to be no icon on my desktop and I am unable to search for it through "Start". Could this be because I have the 32-bit version of Anaconda downloaded and I have a 64-bit OS (I thought I should do this because Python on my computer was 64-bit) or because I downloaded Anaconda under "users" instead of Desktop. I also downloaded Anaconda twice, if that could be causing some of the problem. I have a Windows 10 laptop, if that is any help.
Try to
source ~/anaconda3/bin/activate root
anaconda-navigator
https://github.com/ContinuumIO/anaconda-issues/issues/1580
Open up a command terminal (CTRL+ALT+T)
and try running this command:
anaconda-navigator
When I installed Anaconda, and read the website docs, they said that they tend to not add a file or menu path to run the navigator because there are so many different versions of different systems, instead they give the above terminal command to start the navigator GUI and advise on setting up a shortcut to do this process manually - if that works for you it shouldn't be too much trouble to do it this way - I do it like this personally
How I solved this issue:
1. Be connected to the internet.
2. Open the Anaconda Prompt (looks like a regular command window).
If you installed the .exe in your /name/user/ location you should be fine, if not navigate to it.
Then start an environment.
conda info --envs
Then run
conda install -c anaconda anaconda-navigator
Press y when prompted (if prompted). It will being downloading the packages needed.
Then run your newly installed Anaconda Navigator
anaconda-navigator
It should start, and also appear in your regular windows 10 apps list.
activate the virtual env with command:
conda activate base
run anacond anavigator
anaconda-navigator
when you will type anaconda in windows 10 search bar it will give you the list as
then in terminal you have to type anaconda-navigator as
it will start anaconda on your machine.
Yet another option which worked in my case on Windows 10: Try uninstalling your previous installation, restart the system and run the installation again. Make sure you don't start any programs before installing Anaconda. You will find the installation finishes without prompting any kind of errors.
Type in Anaconda in your Windows 10 Search bar. You will find Anaconda Prompt appear.
I figured out the reason as to why:
1-There seems to be no navigator icon
2-When conducting the above steps of running the "anaconda-navigator" command in prompt (whether cmd or Anaconda) it yields "anaconda navigator is not recognized as an internal or external command"
This was very frustrating to me as I'd installed the proper version multiple times with no avail.
To solve this problem :
in the installation process, there will be an advanced options step with 2 selections one of which is unchecked (the top one). Make sure you check it which will add the navigator to the path of your machine variables.
Cheers,
Hossam
it works :
export PATH=/home/yourUserName/anaconda3/bin:$PATH
after that run anaconda-navigator command. remember anaconda can't in Sudo mode, so don't use sudo at all.
I faced the same problem on Windows 10. As soon as I cleared my Path variable from edit environment variables option, the icon started to appear. It was occurring because I had previously installed python 3.6.1 on my computer and added it to my path variable as C:\Python36;C:\Python36\DLL; and so on. There isn't any need to uninstall Anaconda Navigator and start from scratch if you have correctly followed the steps mentioned at the documentation for it.
Try restarting the system! You will be able to find the navigator once you restart the system after installation.
Tried all solutions here but these 2 steps solved the issue:
1) manual update of open-ssl from here:
https://slproweb.com/products/Win32OpenSSL.html
2) update OpenSSL using conda update openssl command in the Anaconda Prompt
solved the issue!
I had a similar issue today where only the prompt was available after installation.
Finally solved this by un-installing my regular python installation and then install anaconda(anaconda 3 v5.2.0, with python 3.6).
I also have the issue on windows when i am unable to find the anaconda-navigator in start menu.
First you have to check anaconda-navigator.exe file in your anaconda folder if this file is present it means you have installed it properly otherwise there is some problem and you have to reinstall it.
Before reinstalling this points to be noticed
1) You have to uninstall all previous python folder
2) Check you environment variable and clear all previous python path
After this install anaconda
your problem will be resolved if not tell me the full error i will try to solve it
Uninstall your Anaconda, delete the folder where it was. Then reinstall it.
You might not be in a anaconda environment
Below is a link how to activate the environment from the official documentation
On Windows, in your Anaconda Prompt, run activate myenv
https://conda.io/docs/user-guide/tasks/manage-environments.html#activating-an-environment
And then run the anaconda navigator from the anaconda prompt by entering the command anaconda-navigator
100% Solved.
While Installing make sure you are connected to Internet.
If already installed anaconda, open the anaconda command prompt and type following command:
conda install -c anaconda anaconda-navigator
(internet connection is required)
Note: In some cases restarting may solve the issue of navigator.
This is what I did
Reinstall anacoda with ticked first check box
Remember to Restart
I have that error an the solution was to install the Win64 OpenSSL.
https://slproweb.com/products/Win32OpenSSL.html
Download and install Miniconda first from this link and later on download and install Anaconda. Then you will be able to see the navigator in your all programs list in the start menu. I hope this will help you. Let me know in case of any concerns.
In my case; it was available in the anaconda folder in "All App" from main menu
For people from Brazil
There is a security software called Warsaw (used for home banking) that must be uninstalled! After you can install it back again.
After thousand times trying, installing, uninstalling, cleanning-up the regedit that finally solved the problem.
First Run This Command
conda config --set auto_activate_base True
Then Run This Command
anaconda-navigator.
Turn off your internet connection, then open your terminal and type anaconda-navigator or type anaconda prompt in the search bar and double click on the anaconda prompt.
If anaconda is opened, then you can turn on your Wi-Fi.
I'm also faced with this issue. When I checked conda --version got a command not recognized error. Then I set the environmental variables as in https://stackoverflow.com/a/61372328/13370201. After that run anaconda navigator command. Then it started to initializing anaconda navigator.This tutorial also help for me.
I faced the same problem in Solus Baidge but I solved by activating the conda environment.
First activate
conda activate
Then run the navigator
anaconda-navigator
Make sure to run the installer as admin
In my case (Windows 11) it was a permission problem. Make sure to run the installer as administrator. You can check this by modification of the path in the installer process.
Further steps to handle the problem:
Uninstall your actual anaconda version.
Delete old Data found in:
C:\Users\YourUsername\AppData\Roaming
C:\Users\YourUsername
(In my case it was called .anaconda and .conda folder)
Restart PC
Install Anaconda as admin
The followng command solved my issue.
pip install --upgrade pywin32==228
On windows 10, I faced the same error - only Anaconda Prompt was showing in the startup menu. What I did is i re-installed Anaconda and selected install for all users of the pc (in my initial installation I have installed only for current user).
What finally worked for me was:
Uninstalling Anaconda
Deleting all files that has "conda" in them - most of them should be
located in: C:\Users\Admin
Delete especially the "condarc" file.
Reboot
Installed 32-bit installer (even though my system is 64-bit) and reboot
Finally worked. I have not yet re-tried with 64-bit installer, since I have a time critical project, but will do when again I have spare time.
P.S. what broke Anaconda for me was a blue screen I got while updating Anaconda. I guess it did not clear all old files and this broke the new installs.
I too faced a similar issue when I was not able to find the Anaconda Navigator Desktop app in the start menu. But do not worry , Go to start Menu and Type Anaconda Navigator. Now within the apps menu you will find anaconda navigator with its icon. Click on that. After clicking you will find a command prompt dialog opened and a .exe file runs on your machine. Wait till it completes.
The Anaconda Navigator app opens on your machine.

Anaconda3 2.4 with python 3.5 installation error (procedure entry not found; Windows 10)

I have just made up my mind to change from python 2.7 to python 3.5 and therefore tried to reinstall Anaconda (64 bit) with the 3.5 environment. When I try to install the package I get several errors in the form of (translation from German, so maybe not exact):
The procedure entry "__telemetry_main_return_trigger" could not be found in the DLL "C:\Anaconda3\pythonw.exe".
and
The procedure entry "__telemetry_main_invoke_trigger" could not be found in the DLL "C:\Anaconda3\python35.dll".
The title of the second error message box still points to pythonw.exe. Both errors appear several times - every time an extraction was completed. The installation progress box reads
[...]
extraction complete.
Execute: "C:\Anaconda3\pythonw.exe" "C:\Anaconda3\Lib_nsis.py" postpkg
After torturing myself through the installation I get the warning
Failed to create Anaconda menus
If I ignore it once gives me my lovely error messages and tells me that
Failed to initialize Anaconda directories
then
Failed to add Anaconda to the system PATH
Of course nothing works, if I dare to use this mess it installs. What might go wrong? On other computers with Windows 10 it works well.
P.S.: An installation of Anaconda2 2.4 with python 2.7 works without any error message, but still is not able to be used (other errors).
Finally I have found the reason. So, if anybody else has this problem:
Here the entry points are an issue as well and Michael Sarahan gives the solution. Install the Visual C++ Redistributable for Visual Studio 2015, which is used by the new version of python, first. After that install the Anaconda-package and it should work like a charm.
You can also use your standard Anaconda installation and just create an environment based on 2.7 / 3.4 etc... Anaconda will download and install all compatible packages from the repository so you have a complete installation.
conda create -n py27 python=2.7 anaconda
conda create -n py34 python=3.4 anaconda
To use the new environment (in Windows), you can point your IDE to the required environment folder:
C:\Anaconda3\envs\py34\python.exe
On the Windows command line, you just need to type:
activate py34
Documentation:
http://conda.pydata.org/docs/py2or3.html
My recommendation would be to reinstall your Anaconda version with Python 2.7 that you previously had working, then just add a new environment for Python 3.x and use that as you need.
I had the same problem, then I Installed "for all users": solved.
Much easier than the links provided for a beginner as I am.
For the problem "Failed to create Anaconda menus", it may because:
This might happen if PATH is too long already. How long is your PATH environment variable? Windows limits this to 1024 characters. There are some workarounds go shorten it here: How do you avoid over-populating the PATH Environment Variable in Windows?
This is other people's question and solution
https://groups.google.com/a/continuum.io/forum/#!topic/anaconda/mjrbE6rKyi8
When I shorted the environment path, it works!
If you are getting errors like:
Failed to create Anaconda menus
Failed to initialize Anaconda directories
Failed to add Anaconda to the system PATH
just ignore them while installation and when installation is done look for the directory "anaconda3" is installed and correct the path accordingly in environment variables path.
In my system, path was set "C:\Anaconda3" but actually it was installed at "C:\ProgramData\Anaconda3". You have to change all 3 path entries for anaconda3 and then try to run "jupyter notebook" in CMD.
If you are using windows, launch the command prompt as administrator and execute the following commands
"C:\ProgramData\Anaconda3\pythonw.exe" -E -s "C:\ProgramData\Anaconda3\Lib_nsis.py" addpath
"C:\ProgramData\Anaconda3\pythonw.exe" -E -s "C:\ProgramData\Anaconda3\Lib_nsis.py" mkdirs
"C:\ProgramData\Anaconda3\pythonw.exe" -E -s "C:\ProgramData\Anaconda3\Lib_nsis.py" mkmenus
Don't forget to change the path to the path in your system. Before running this commands there will not be any Anaconda Navigator app in your start menu. After executing this commands make sure Anaconda Navigator app is available in the start menu.
Change the directory. It works
C:\miniconda3
