Hi,
I will retrain in a Ubuntu server, a model with the new prerelease 0.4-alpha.2 and the new CTC hoping it will improve the WER and get more or less the same results as for 0.1 version (with the same data).
As the CTC has changed, and so the generate_trie binary, I am questioning if the quantization in the language_model binary file is still mandatory.
On the other hand, I get this error from DeepSpeech.py :
from ds_ctcdecoder import ctc_beam_search_decoder_batch, Scorer
ModuleNotFoundError: No module named 'ds_ctcdecoder'
I have executed this before:
$ pip3 install -r requirements.txt
$ pip3 install deepspeech-gpu==0.4.0a2
Is there something else to install?
I have executed this to get the url:
$ python3 util/taskcluster.py --arch gpu --decoder
And then try to install it, but already fails :
