Problem with preprocess common voice dataset

I installed deepspeech 7 release and try test recognition. All worked ok. After this i try ro prepare dataset according to instruction https://deepspeech.readthedocs.io/en/v0.7.0/TRAINING.html
.
I try
bin/import_cv2.py --filter_alphabet path/to/some/alphabet.txt /path/to/extracted/language/archive

but have an error

(deepspeech-train-venv) (base) v@gpu:~/ASR/DeepSpeech$ bin/import_cv2.py --filter_alphabet data-cv/extracted/ru/alphabet.txt /data-cv/extracted/ru/archive

Traceback (most recent call last):

Please help me how to solve this problem.

What part of the doc did you missed reading ? https://deepspeech.readthedocs.io/en/v0.7.0/TRAINING.html#installing-deepspeech-training-code-and-its-dependencies
Itā€™s explicitely documented here, and you linked that very same doc.

I did this steps
git clone https://github.com/mozilla/DeepSpeech

python3 -m venv $HOME/ASR/deepspeech-train-venv/

source $HOME/ASR/deepspeech-train-venv/bin/activate

cd DeepSpeech
pip3 install --upgrade pip==20.0.2 wheel==0.34.2 setuptools==46.1.3
pip3 install --upgrade --force-reinstall -e .

sudo apt-get install python3-dev

bin/import_cv2.py --filter_alphabet path/to/some/alphabet.txt /path/to/extracted/language/archive

I missed part recommendations ( i want to try without GPU for begin).

Iā€™m wondering if you are running importer with the proper Python binary ā€¦ Could you please verify / share logs to ensure your install was successfull?

This explicitely states you have not properly installed.

Please pip list and pip3 list before running bin/import_cv2.py

Thanks for help. I repeat installation and all work. It convert dataset.

Thanks, if you can identify what was unclear / error prone in the docs and that you can send a PR to improve, this is welcome.

There are some unclear moments in documentation.
1.
https://deepspeech.readthedocs.io/en/v0.7.0/TRAINING.html
installing for training
and
https://deepspeech.readthedocs.io/en/v0.7.0/USING.html
installing for using
What is the difference ?
When i installed for using i can recognize. And deepspeech command work.
When i installed all for training dataset preparation work good , but

./DeepSpeech.py --train_files ~/ASR/data-cv/clips/train.csv --dev_files ~/ASR/data-cv/clips/dev.csv --test_files ~/ASR/data-cv/clips/test.csv
bash: ./DeepSpeech.py: ŠžŃ‚ŠŗŠ°Š·Š°Š½Š¾ Š² Š“Š¾ŃŃ‚ŃƒŠæŠµ
doesnā€™t work.

Why should i install deepseepch for using with pip but install for training with git clone ( not with pip) ?
Can i use first enviroments ( for recognition ) for training ?

Training and inference are completely separate tasks. If you just want to do inference, you donā€™t have to install the training package. If you just want to do training, you donā€™t have to install the inference package. This is why the training package is called deepspeech_training, to make it extra clear what itā€™s for.

You should ideally use separate virtual environments for training and inference.

The error you got is because DeepSpeech.py is not executable. Use python DeepSpeech.py as we show in the docs. You should familiarize yourself with the Linux command-line, itā€™ll help you immensely with training tasks (and in general).

Thanks for explanations. I expected this difference. Python DeepSpeech works ( but give some errors during execution).
I think it wold be better to give exact commands in documentation with python command.
bin/import_cv2.py ā€¦
works without python bin/import_cv2.py

but DeepSpeech.py not.

Ugh, I just realized there were some commands in docs using ./ instead of calling Python directly. Iā€™ve made a PR fixing it. Thanks for the feedback.
