TypeError: '>=' not supported between instances of 'NoneType' and 'int' using custom wav2vec2

[C00reNUT]

Hello,

Thank you for marking this public!

Everything works very nicely with the default model, but I wanted to compare the results using wav2vec2 model finetuned on my own, czech language using

ctc-forced-aligner --audio_path "Moudry_zlatnik.wav" --text_path "Moudry_zlatnik.txt" --language "ces" --romanize --alignment_model badrex/xlsr-czech

the model is from repo https://huggingface.co/badrex/xlsr-czech

When I run the cli command i get:

/mnt/a0b764eb-cdc5-4f46-9a2e-e2f11deba631/PYTHON_CACHE/ctc-forced-aligner/lib/python3.11/site-packages/transformers/utils/hub.py:127: FutureWarning: Using `TRANSFORMERS_CACHE` is deprecated and will be removed in v5 of Transformers. Use `HF_HOME` instead.

Any ideas how I could fix this?

should be fixed in the last commit

Sadly, even after latest pull, the issue still persist.

přestaň s tím povypováním.
Zpívám si jen tak potichu.
Rušíš můj odpočínek.
Můžeš si najít místo pod jiným stromem.
A mě se líbí tady, pod javorem.
Jenže já to byla dřív.
Stejně ti nezbude, než pustit mě na své místo.
Tohle říkáš celé věky, co se potkáváme a přece jsem ti ještě nikdy neuhnula z cesty.
Tak ty jednou vstoupíš.
Nevím proč.
Protože rozum, děvče, rozum nakonec musí mít vrt.
Domýšlivost ti zakrývá oči?
Jinak bys viděl, že mne mají lidé raději než tebe.
Snad ne za ty tvé popěvky.
Za radost a za útichu.
Někdy za naději.
Nebuď pošetivá.

Could you please try this text with some audio wav file and the badrex/xlsr-czech alignment model to test it?

[MahmoudAshraf97]

I just tested it again, I couldn't reproduce the same error, please note that the usage instructions have ben slightly changed so refer to the readme

[C00reNUT]

Yes, but cli instructions didn't change just code, I still run the same cli command

ctc-forced-aligner --audio_path audio.wav --text_path text.txt --language "ces" --alignment_model badrex/xlsr-czech

and still get

I have tried multiple wav2vec2 czech models, but I get the same error for all of them: https://huggingface.co/badrex/xlsr-czech https://huggingface.co/arampacha/wav2vec2-large-xlsr-czech https://huggingface.co/comodoro/wav2vec2-xls-r-300m-cs-250

Strange, probably I am doing something wrong... because when I run your default example command

ctc-forced-aligner --audio_path "audio.wav" --text_path "text.txt" --language "ara" --alignment_model "jonatasgrosman/wav2vec2-large-xlsr-53-arabic"

using the same text and audio that runs just fine using default model (but I get the error mentioned in the previous comment) I get
