I am using Whisper to transcribe and I am getting the below error, unable to figure out the issue.

[Suma-Rajashankar]

I am using Whisper to transcribe an audio file. I have installed Python3.9, ffmpeg and the associated dependencies, and openai-whisper==20230308. I could import whisper, but when I try to run transcribe:

audio = f'audio/testaudio.wav' model = whisper.load_model("base")
result = model.transcribe(audio, fp16=False,language="en")

...I get the following error:

ValueError                                Traceback (most recent call last)

----> 1 result = model.transcribe(audio, fp16=False, language="en")

    524 # inference: implements the forward pass through the decoder, including kv caching
    525 self.inference = PyTorchInference(model, len(self.initial_tokens))

ValueError: tuple.index(x): x not in tuple

Has anybody faced a similar issue? Any help would be appreciated. Thank you.

I had the same error in decoding.py, but on a different line (still setting self.sot_index though). If you compare the line of the error your getting with the current source code, you'll see the source code has since been updated.

I simply updated my version of whisper to get it working.
pip install -U openai-whisper

Thank you so much Chris for your feedback. Yes, I uninstalled openai-whisper and reinstalled it with the latest version and it's working now.
