Hi, I have a problem on running train.py.
Here is traceback.

I installed using above requirements and get this error now.

(wav2letter-venv) enchant@tf-server:~/wav2letter/wav2letter.pytorch$ python train.py --train-manifest ~/data/CV/en/clips/train.csv --val-manifest ~/data/CV/en/clips/dev.csv
Traceback (most recent call last):

so I re-install warpctc and ctcdecode but the same result.

[vaibhav0195]

For the warp ctc error,
I think the error is related to - SeanNaren/warp-ctc#103 .
Hope this helps.

I am getting exactly the same problem.
I checked, my versions are up to date.
@IAmEnchant did this solution work for you ?

[vaibhav0195]

Hi @ishita1995
what are your versions of pytorch and cuda ?
can you please tell me your lib versions ?

Thanks
