Hi I am unable to download the ds_ctcdecoder which is required for training my model.

I am getting the below error: no such option: --decoder)

My taskcluster.py file is located in the following file path:

C:\Users\ritis\Anaconda3\DeepSpeech-0.6.1\util\taskcluster.py

Need Help.

Need text instead of screenshot.

I’m not sure the pip3 install $(python3 util/taskcluster.py --decoder) syntax works under cmd. Please use a real shell.

Post your feedback, I have changed to linux. Still I am getting the following error :

If you’re using v0.6.1 models, make sure you’re also using v0.6.1 code. If you cloned the code with Git you can simply checkout the tag with git checkout v0.6.1. Your message suggests you’re using a version from master, which is not compatible with v0.6.1.

Please follow the documentation: Training Your Own Model — Mozilla DeepSpeech 0.10.0-alpha.3 documentation

You have not performed the pip install -e step, at least.

Sir, so you mean to say after I have git cloned : git clone https://github.com/mozilla/DeepSpeech ; I must type : git checkout v0.6.1 to migrate to the v0.6.1 branch?

The reason I am asking is because, I have not seen this code in the link : https://deepspeech.readthedocs.io/en/v0.6.1/TRAINING.html. It is cloning v0.7.3alpha instead directly.

Please help.

If you are just starting with DeepSpeech, stick to the 0.6.1 branch to get to know everything, find docs and commands in this thread:
