Azure-functions-core-tools: Error "ModuleNotFoundError" on local module

Created on 4 Sep 2019  ·  3Comments  ·  Source: Azure/azure-functions-core-tools

The problem:

I am currently trying to deploy my own Azure-Functions-App. The deployment was successfull, but I get the error (see below) when I test the HTTP-Trigger-Function. The local server (started with func_start_host) runs fine and answers my calls.

What I have done so far:

I already read multiple issues with similar but not the same error message

What I expect:

I expect a working HTTP-Trigger and some logs. I am not getting any logs out of it.

Error:

Your CLI is up-to-date.

Edit:
I am relatively new to Azure and found another log indicating that one of my files is not found:

Exception while executing function: Functions.predict Result: Failure
Exception: ModuleNotFoundError: No module named 'predict'
Stack:   File "/usr/local/lib/python3.6/site-packages/azure_functions_worker/dispatcher.py", line 239, in _handle__function_load_request

  File "/home/site/wwwroot/predict/__init__.py", line 4, in <module>
    import predict.azure_tf_model_function as amf

I tried building with --build-native-deps but got the same error on the cloud.

Can you try 

from __app__ import predict.azure_tf_model_function as amf

as suggested in our docs?

from __app__.predict import azure_tf_model_function as amf

This did the trick for me. Thank you for your help, I didn't read that part of the docs.
I am still getting errors, but these are due to missing requirements.
