Testing for correctness of the samples

@lissyx I am not getting the RIFF error. I am getting the EOFError. My files are .wav

I am now able to attach the CSV files. Can you please help?

The command I am using is:

python3 DeepSpeech.py --drop_source_layers 1 --alphabet_config_path /$HOME/Uploads/UrduAlphabet_newscrawl2.txt --checkpoint_dir /$HOME/DeepSpeech/dataset/trained_load_checkpoint --train_files /$HOME/Uploads/trainis.csv --dev_files /$HOME/Uploads/devis.csv --test_files /$HOME/Uploads/testis.csv --epochs 2 --train_batch_size 32 --export_dir /$HOME/DeepSpeech/dataset/urdu_trained --export_file_name urdu --test_batch_size 12 --learning_rate 0.00001 --reduce_lr_on_plateau true --scorer /$HOME/Uploads/kenlm.scorer

This is all set up on Ubuntu 16 with the default installation as on the web site. The setup is working fine for smaller files but doesn’t work when I try to combine transcripts from multiple sources into the same training file.
