Hi all, I am trying embed custom python module in c++ func called by a cocoa app recently and get stuck in the `ModuleNotFoundError`.I created 2 projects using xcode, app1 & app2. The first one is an Command Line Tool app and the second one is a Cocoa app. Meanwhile, I created 2 .py file for them separately and get 2 folders look like below.The code of the BNRcallApp1.cpp and the BNRcallApp2.cpp are basically the same and The 2 .py file are exactly the same, while the app1 works fine and the app2 keeps on yelling that there is a ModuleNotFoundError.I have already tried the following instructions:sys.path.append or sys.path.insert ---doesn't workadd __init__.py to app2 or app2/app2 or both ---doesn't workadd .pth with the content /Users/ABC/Desktop/app2/app2 to the /usr/local/ opt/python/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages ---doesn't workcopy the BNRapp2.py file to the folder /usr/local/opt/python/Frameworks/ Python.framework/Versions/3.7/lib/python3.7/site-packages ---doesn't workcopy the BNRapp2.py file to the folder /usr/local/opt/python/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload or /usr/local/opt/ python/Frameworks/Python.framework/Versions/3.7/lib/python3.7 ---work fine!What am I missing here? Is there any particular configures needed to be set when it comes to Cocoa app? Any help?
