I tried following the steps listed on your site for python bindings install but still not able to access it.
I am having windows 11, latest Cmake, Python 3.10, and VS2022.
Here is the error log when i am trying to run HowTo\_AcuteStress.py :
ModuleNotFoundError: No module named ‘pulse’
it seems, something is missing ?

Make sure you have the Pulse install/bin directory in your PYTHONPATH
Make sure you have a file named PyPulse.cp310-win\_amd64.pyd in your install/bin directory

I have done both of the things still unable to run Howto\_AcuteStress.py.
I have PyPulse.cp313-win\_amd64 in my bin folder and also added this dir to PYTHONPATH in Env Variables.
I am uploading image of Pycharm, I am following your listed steps but it is giving me errors.
Please help!
PS- Current Error:
C:\Users\masti\AppData\Local\Programs\Python\Python313\python.exe D:\lung\Pulse\builds\install\bin\HowTo\_AcuteStress.py

See if these instructions on setting up PyCharm helps

The project should be the pulse\_source/src/python folder, not the install folder
And you need to edit the pythonpath of the python interpreter, not via Environment variables
