Libri-clean decoder fails

[AlexandderGorodetski]

Question

Hello,

I have just updated my wav2letter docker and I found that my simple decoder based on libri-clean training does not work.

Following is the error message: Invalid dictionary filepath specified

Following is the content of my decode.cfg file:

Decoding config for Mini Librispeech

Replace [...] with appropriate paths

--lexicon=/media_alex/common/projects/wav2letter/db/libri-100/lm/lexicon.txt --lm=/media_alex/common/projects/wav2letter/db/libri-100/lm/3-gram.arpa --am=/media_alex/common/projects/wav2letter/exp/libri-100/librispeech_clean_trainlogs/001_model_lists#dev-clean.lst.bin --test=lists/test-clean.lst --sclite=/media_alex/common/projects/wav2letter/exp/libri-100/decode --lmweight=2.5 --wordscore=1 --beamsize=500 --beamthreshold=25 --silweight=-0.5 --nthread_decoder=4 --smearing=max --show=true

@AlexandderGorodetski, you need to fix tokensdir and tokens, I guess it is trying to load the paths you used in the training, you can check them in the log printed on the screen, which values for them are set and if the tokens path exists.

also, a couple of decoding options have been changed (as we improved the decoders) a while ago (for example, silweight is no longer valid, but there is silscore instead).
