Beginners Question

Hello,

I am sorry but I thought I installed EMERGE as descirbed in the READ.ME file and tried to run the demo1_stepped_imp_filter.py. file
I am in Windows, VS Code.
I go this error message, which seems to say that python cannot see the emerge module.
Please advise
Thank you

Hey! No problem, ill see if i can help.

Managing packages in windows can be tricky because windows makes it hard to change PATH variables etc.

Have you tried: py3 -m pip install emerge?

Specifically also try it in the terminal of VSCode.
You may also try
python3 -m pip install emerge

Thank you
yes, I tried your suggestions.
It says requirement already satisfied and the problem stays the same, so maybe the problem is somewere else

I'll help you as well as I can. This might take some effort. Windows can be tricky that way.

So when you launch your code in VS Code you can see this:

File "c:\Users\NA\OneDrive\OneDriveDocuments\Python\WPy64_31110_env()

This shows that when you launch your python code in VS Code it runs the python installed in OneDriveDocuments\Python\WPy64_31110_env()

If you open a windows PowerShell terminal (start > type: powershell then launch), you can type the following

(Get-Command python).Source

That should tell you which executable it is picking when you type:

python -m pip install emerge

If its not the same as the one VS Code picks then that is why the module doesn't show up.

The executable you show is likely a WinPython distribution, not the usual Python that you download from the official website. I reccomend you to download an installer on: https://www.python.org/downloads/windows/

You can try the latest python version but you might have some difficulty with packages. I think EMerge is fully compatible with 3.13 though. Run the installer and at the beginning check the "add Python to PATH" check mark. If you only run this python installation to use EMerge and not do any other development on the side, this is the easiest. It will add the Python path to the PATH variable which means that if you type something like python in your terminal, windows will know that it should launch that version.

If you then open a new terminal after installation and run the command

(Get-Command python).Source

I think it should default to that one. If it shows something else, please let me know. There are plenty of tricks to get this to work properly

I personally don't develop on windows so its also a bit of debugging for me.

I am going to try to make a complete beginner installation guide at some point to prevent this. Windows can be quite annoying.
