Installing Additional Python Packages in Sim4Life Environment

[andrea_h]

Hi all,

I have been working with the Sim4Life Visual Studio Code Extension. While some modules like numpy work perfectly, others give a "ModuleNotFoundError."

I believe this is because I am running my script in the Sim4Life environment, and certain packages are not included by default.

My question is: Is there a way to install additional packages within the Sim4Life environment so I can use them in my scripts?

Any suggestions or guidance would be greatly appreciated!

yes, you can install additional packages in the Python environment that Sim4Life is running. Simply type this in a console (using e.g. "cmd.exe"):

"C:\Program Files\Sim4Life_xyz\Python\python.exe" -m pip install package_name

adjusting for Sim4Life's version number and your package_name.
You most likely won't even need to restart Sim4Life.

Thanks for your response! It worked perfectly (without even restarting Sim4Life)

@Sylvain I would like to add new packages too (e.g., dipy), but I don't have such directory in my computer, is it a problem?
Despite the fact I have not a python.exe, I can run Python script in Sim4Life.
Thanks in advance!

@gc00 try typing this in Sim4Life's console (View -> Console), it will give you a clue as to the location of the Python directory:

import os
print(os.__file__)

@Sylvain it printed: C:\Program Files\Sim4Life_7.2.3.12730\Python\lib\os.py

[Sylvain]

then it means that you can find python.exe in this directory:
C:\Program Files\Sim4Life_7.2.3.12730\Python

So you should be able to run:

"C:\Program Files\Sim4Life_7.2.3.12730\Python\python.exe" -m pip install package_name

from Windows' console (NOT the Console of Sim4Life)

@Sylvain Yes thanks finally I succeed!
