InvalidArgumentError: Timit training

[menamine]

Hi all,

I tried to train a character based speech recognition system by using the Timit corpus. I prepared data (features and labels), however, I got an error in the training process (the attached figure).

The issue is when I use a small data set for training (10 wav files), no errors occur. But if I increase the size of the training data set, I got the InvalidArgumentError error

Any help is greatly appreciated.
Best.
