Unable to run faster-whisper in tests

[ruliworst]

Hi,

I am trying to run a transcription in a test (pytest) but an error is raised:

Error while running tests:
TypeError: Cannot read properties of null (reading 'testsuites')

The line when the test crashes is (line 629, /faster-whisper/transcribe.py):

        return self.model.encode(features, to_cpu=to_cpu)

Any help is appreciated. Thanks in advance.

Hello. It seems that your problem is not a bug from faster whisper. I found the same error occurring with VS code:
microsoft/vscode-python#21176
microsoft/vscode-python#14107
Can you run faster-whisper without pytest? Or can you show your pytest code ?

Hi,

Can you run faster-whisper without pytest? // Yes, I can.

Or can you show your pytest code ? // Sure.

import faster_whisper as fw

def test():
  model = fw.WhisperModel(
     model_size_or_path = "C:/Downloads/faster-base",
     local_files_only = True,
     device = "auto")

  model.transcribe("C:/Downloads/audio.wav")

It fails in model.transcribe line.

Hi. Your test is quite simple and I think it has no logic errors (except for changing fs => fw). In addition, you can refer to the transcribe tests in this project:
https://github.com/SYSTRAN/faster-whisper/blob/master/tests/test_transcribe.py

Yes sorry, that was an error copying the code.

Thank you very much, I'll check it.

Hi again, the problem was in device parameter. If it is set to 'auto' for some reason the GPU is not detected but, if I set device to 'cpu' it runs properly. Thanks a lot guys.
