Bug with Mac about anylogic-pypeline

It seems like you're trying to programmatically create the Python Communicator agent? If you can share your model, it would help in troubleshooting.

Thank you for your quick reply.
The model I try to run is the Simple Hospital (AI Tested) from the exemples.

When I try to use python3, I get this error :
Error during model startup:
root.pyCom:
ModuleNotFoundError("No module named 'numpy'")java.lang.RuntimeException:

Ah right, I see what the problem is now. Macs have Python 2 installed by default, so if you initialize the PyCommunicator with the default python, that's what it uses, and Pypeline does not support Python 2.

Your update fixes to use Python 3 but as the error suggests, you're missing the numpy library, so you'll need to install that (and any other dependencies mentioned by the model). The simplest way that usually works is doing the following in a terminal: python3 -m pip install <library> (replacing "<library>" with the library name)

Thank you for your reply.
The thing is I already installed this package
(python3 -m pip install numpy
Requirement already satisfied: numpy in /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages (1.19.5)).

This is why I don't understand. Does it need a special env to run ?

There might be a weird path issue happening related to you being on a Mac (I admittedly haven't extensively tested Pypeline on it).

Try creating a new model and following the instructions listed on the Wiki's Setup page but configure it to use the "python3" command. Make sure the path it shows is similar to the mentioned one. If it's not, let me know what it is
