Problem when using azure cognitive services (.dll file not found)

Question

I have an app made with flask that is working fine on my machine. I'm trying to move it to a server in order to make in accessible to some people. I've installed all the packages and check that everything has the same version as on my local machine.

Everything seems fine but when I try to run the app, it throws this error:

FileNotFoundError: Could not find module 'C:\Users\Sparapan.F\Desktop\Scripts\Trascrittore\Tutto\trasc_env\Lib\site-packages\azure\cognitiveservices\speech\Microsoft.CognitiveServices.Speech.core.dll' (or
one of its dependencies). Try using the full path with constructor syntax.zen runpy>

The missing file is actually present in the specified folder so I don't know what to do. Already tried: --uninstall and re-install cognitive services

-check python and system versions (both 64 bit)

-restart the system

Hi F. Sparapan - Gruppo Finservice

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

It seems that you are encountering a FileNotFoundError related to the Microsoft.CognitiveServices.Speech.core.dll file when trying to run your Flask app.

Here are some troubleshooting steps:

1. Please make sure that you have installed compatible python version as per your system (for e.g. 32-bit Python compiler for 32-bit system.
2. Please check with stable release of python like Python 3.11 or 3.12.
3. Un-install and Re-install the package if there are no compatibility issue.

Use the following commands:

pip uninstall azure-cognitiveservices-speech 
pip install azure-cognitiveservices-speech

Refer thread: filenotfounderror

Hope this helps. Do let us know if you any further queries.
