Deepspeech: Required version of ds-ctcdecoder does not exit

[dabadiesimon]

Running on Debian 9.12 - Python 3.7.6- deepspeech-training==0.9.0a0

when executing pip3 install --upgrade -e .

Deepspeech requires _ds_ctcdecoder==0.9.0-alpha.0_.
However, this version does not exist as can be seen on dedicated pypi.org page

Full error:

ERROR: Could not find a version that satisfies the requirement ds_ctcdecoder==0.9.0-alpha.0 (from deepspeech-training==0.9.0a0) (from versions: 0.6.1, 0.7.0, 0.7.1, 0.7.3, 0.7.4, 0.8.0a3, 0.8.0a4)
ERROR: No matching distribution found for ds_ctcdecoder==0.9.0-alpha.0 (from deepspeech-training==0.9.0a0)

This can be resolved by using a release, e.g. 0.7.4, or pre-release, e.g. v0.8.0-alpha.4, not master.

Thanks for the report.
@dabadiesimon Yeah I moved the VERSION file without releasing an alpha build. As said earlier, move to a release tag or be patient and within a few hours a 0.9.0a0 should be there.

[dabadiesimon]

Yes, just to let you know.
Thanks for the quick answers

The 0.9.0a0 has been uploaded.

Hi, I am trying to perform fine-tuning on DeepSpeech's model in Colab. Here are the installation steps I am following-

!git clone https://github.com/mozilla/DeepSpeech
!pip3 install --upgrade pip==20.0.2 wheel==0.34.2 setuptools==46.1.3
!pip3 install --upgrade --force-reinstall -e .

But, I receive this error upon trying to run it -

ERROR: Could not find a version that satisfies the requirement ds_ctcdecoder==training/deepspeech_training/VERSION (from deepspeech-training===training-deepspeech-training-VERSION) (from versions: 0.6.1, 0.7.0, 0.7.1, 0.7.3, 0.7.4, 0.8.0a3, 0.8.0a4, 0.8.0a5, 0.8.0a6, 0.8.0a7, 0.8.0a8, 0.8.0, 0.8.1, 0.8.2, 0.9.0a0, 0.9.0a1, 0.9.0a2, 0.9.0a3, 0.9.0a4, 0.9.0a5, 0.9.0a8, 0.9.0a9, 0.9.0a10, 0.9.0a11)

Any help will be appreciated! Thanks!
