Converting wisper v3 model with convert-h5-to-ggml.py doent work

[LimonAstuto]

I had an error using convert-h5-to-ggml.py to convert https://huggingface.co/openai/whisper-large-v3

  File "whisper.cpp/models/convert-h5-to-ggml.py", line 115, in <module>
    fout.write(struct.pack("i", hparams["max_length"]))
KeyError: 'max_length'

Thats because there is not a max_length inside whisper-large-v3 config.json

I modified line 115 to:

fout.write(struct.pack("i", hparams.get("max_length", DEFAULT_MAX_LENGHT)))

and added

DEFAULT_MAX_LENGHT = 448

I dont know if this is correct, but it worked for me.

You should use convert-pt-to-ggml.py

Whisper-large-v3 is shipped in pt format not h5

but it worked for me.

Not sure why it works.

Where do I find the .pt file of Whisper-large-v3? Thank's for your help
EDIT: Reading the README inside models. :D

Thank you

PyTorch models don't necessarily need to have a .pt suffix. For more details, see here.
