cannot import N_MELS from whisper.audio

Traceback (most recent call last):
  File "/Users/matt/Clients/Refactor/KJR/zac/classify.py", line 10, in <module>
    from whisper.audio import N_FRAMES, N_MELS, log_mel_spectrogram, pad_or_trim
ImportError: cannot import name 'N_MELS' from 'whisper.audio' (/Users/matt/.pyenv/versions/3.9.7/lib/python3.9/site-packages/whisper/audio.py)```

I suspect I am using an older version of whisper, is there any chance you could let me know whatversion of whisper this is known to work with?

I am very interested in trying to get this code up and running :)
