Citrinet CTC Decoder Alphabet size mismatch.
State: closed | Pull request: no
Labels: name: bug

name: stale

I trained a Citrinet and intended to use the CTC Decoder to retrieve a corrected output. 

Using the CTC Beam Search Decoder of DeepSpeech I get the following error:

[ctc_beam_search_decoder.cpp:279] FATAL: "(alphabet.GetSize()+1) == (class_dim)" check failed. Number of output classes in acoustic model does not match number of labels in the alphabet file. Alphabet file must be the same one that was used to train the acoustic model.

I have controlled the alphabet and it has the size of 1023, even though I built it with 1024 characters. I built the tokenizer and alphabet with the nemo script setting the vocab size to 1024, spe and unigram. The output shape of the model is 1025. I believe the mismatch is 1 character. I thought of blank or unk token, but I aint sure if that is the cause of the error. Any idea why this happens or how to solve it? I appreciate your help!!






yes, it is due to additional `<blank>` token that gets added to the provided tokenizer. 

This issue is stale because it has been open for 30 days with no activity. Remove stale label or comment or this will be closed in 7 days.

[NeMo-UX] Make TE and Apex dependencies optional

# What does this PR do ?

This PR provides a fallback codepath that defaults to pure Pytorch/jit when TE and Apex are not installed. Note that this is specifically designed to work with NeMo 2.0, so there are no guarantees when running with NeMo 1.0 models.

Fix lhotse tests for v1.24.2
State: closed | Pull request: yes
Labels: name: common

name: Run CICD

# What does this PR do ?

These tests were failing on main when torchaudio was present in the container. The changes are caused by the dynamic bucketing sampler optimization in the new lhotse version - the sampler simply draws different buckets in the test setup. I removed the conditional trigger on torchaudio since newer lhotse versions don't require it for the functionalities under test anymore.

Edit: also fixing a new regression in RIR test (the random seed was not fixed).
