Cannot train pre-trained model even after using negative epochs

Deep Speech

I am trying to train pretrained model on aws I downloaded check-point from this link https://github.com/mozilla/DeepSpeech/releases

> python3 DeepSpeech.py --n_hidden 2048 --checkpoint_dir deepspeech-0.4.1-checkpoint --epochs -3 --train_files clips/train.csv --dev_files clips/dev.csv --test_files clips/test.csv --learning_rate 0.00001 --export_dir model/

I dont know what is wrong. i have already trained on my laptop then I started from scratch in aws. but its not working
I found the similar question but it was because the guy that posted the question did not provide negative value as epochs but I have provided -3 as epochs.
what could be causing this erros, any ideas.

Can you elaborate ? What you show here is that it did export a model as expected. I’m not sure what you mean when you say “its not working”.

#3

@lissyx but it should have started training

I started optimization
i am training on epoch something

its not starting epochs

#4

We changed the behavior, are you running master or 0.4.1 ?

#5

@lissyx I am using 0.4.1
thanks for fast reply

#6

You’re mixing things up between master and v0.4.1. For example, in v0.4.1, there’s no --epochs flag.
