[Zoo-discuss] Zoo kernel not loading Python services

[Fenoy Gerald]

Hello,
I suppose that you have set the value « test.py » in your zcfg file for the serviceProvider. Nevertheless, it is not require to write the extension .py to the python module to be loaded. So you should use test rather than test.py to solve your issue.

In case you have a subdirectory named test, then you may try adding a __init__.py file to make the ZOO-Kernel able to find the py module located in the test subdirectory.

I hope it helps and yo can confirm that your issue is solved.

Best regards,
