Error when trying to train

DeepSpeech
#1

Hi,
I was following the instructions to train the model, but I getting the below error. Can some one please help me identify why I am getting this error and how can I get this fixed?

Can you make sure you post the stacktrace using backquotes? Otherwhise some characters are missing and it’s harder to read :slight_smile:

like that
#3

The error mentions wav_filesize, can you make sur your CSV files does have that column?

#4

I checked and the header “wav_filesize” exists in all the files. I am trying to attach the csv files here, but this site is not allowing me to upload as I am a new user.

Would appreciate anyone who can help me out with this issue. Any pointers on how I can troubleshoot this one?

#5

Thanks lissyx for taking out the time to reply and trying to help me. I found out what was wrong, had to run DeepSpeech.py in debugger mode to find out.

Turns out there are 2 sets of *.csv files getting generated and I have to pick the csv files in the root folder to train. I was picking the wrong files which had the below headers. I pointed to the right files, problem solved :slight_smile:

Thanks :slight_smile:

#6

what can i do to fix that ?

#7

You are probably using the wrong csv file. See if there are csv files in the parent folder with 3 columns. Use those csv files.

I’m taking the opportunity, since you found your issue, would you mind updating the title with a better wording to make it easier for others to find your specific problem? Thanks!
