Could not install requirement ds-ctcdecoder==0.4.1

DeepSpeech
#1

Hi, I wanted to try training on the Deepspeech version 0.4.1
But when I run this command

pip3 install $(python3 util/taskcluster.py --decoder)

or

pip3 install $(python3 util/taskcluster.py --decoder --branch “v0.4.1”)

It throws this error.

I ensured tensorflow version is 1.12.0

Perhaps @lissyx you can help

Ds_ctcdecoder installation
#2

This artifact expired, you should rebuild it.

#3

I suspected that. Anyways, Thanks for the prompt reply.
You guys are doing great work.

Cheers.

@saksham.vikram12 Did you manage to resolve this error? I’m facing the same error for the same version of deepspeech and can’t find how to rebuild it.

Would you be able to assist? @lissyx

#5

make -C native_client/ctcdecode. You may have to install some dependencies.

#6

After making the decoder again then how to we install it? Or do we need to point at the artifact within the code?

#7

As usual, you will get a wheel, just pip install it…
