No module named 'PySAM'

Hi Paul,

I have successfully installed PySAM. By typing "pip list", I can see:

NREL-PySAM         5.1.0
NREL-PySAM-stubs   3.0.1

However, when I tried to run the following:

import PySAM.Pvsamv1 as pv

I got:

ModuleNotFoundError: No module named 'PySAM'

How can I solve this problem?

Hi Zhaoyun,

I think this is because of your Python environment. Perhaps you have more than one version of Python installed, or are running your script in a virtual environment that does not have access to the PySAM package you installed.

Please try searching the web for "ModuleNotFoundError" to see if you can find a solution.

Best regards,
Paul.

Hi Paul,

Thanks for the quick response. Yes, your guess is correct.

My usual python installation directory is C:\Users\ladmin\AppData\Local\Programs\Python\Python311\Lib\site-packages. However, NREL-PySAM was installed in C:\Users\ladmin\AppData\Roaming\Python\Python312\site-packages. I used the same VS Code terminal to install PySAM. I don't why it is installed in the wrong directory. Do you know how to solve it?

Hi Zhaoyun,

You may want to set up Python virtual environment to manage your Python installation and packages. Some options are Python's `venv` or Anaconda's `conda`.

Best regards,
