I’m getting this error while training the model with Common Voice Dataset

#2

@saravananselvamohan It looks like you improperly setup git-lfs. Please check your setup.

#3

Does that mean the problem with the training environment I created??? For me training of common voice data occurs for almost 5 Epochs. After I am getting this error

#4

The problem is that data/lm/lm.binary and data/lm/trie file are not properly checked out, yes. Please verify and ensure you checkout them properly through git-lfs, as documented.

#6

Still I can’t able to fix the issue…
I Early stop triggered as (for last 4 steps) validation loss: 264.626007 with standard deviation: 3.371662 and mean: 257.793589

Loading the LM will be faster if you build a binary file.

#7

I’ve already told you what was the issue, I can’t fix your setup for you.

#8

Can you explain "data/lm/lm.binary and data/lm/trie " How to check these files are properly checked out?

#9

No, this is already documented, please read the documentation.

#10

Very begining of the documentation: https://github.com/mozilla/DeepSpeech/blob/master/TRAINING.rst#getting-the-training-code “install Git Large File Storage”.
