I downloaded deepspeech checkpoint from github. then i kept the checkpoint in the appropriate directory. I want to retrain the pre-trained model with my own dataset. I run the following and following error. Any suggestion how to resolve the error.
deepspeech-venv) nayan@nayan-virtual-machine:~/Desktop/DeepSpeech$ python3 DeepSpeech.py --n_hidden 2048 --checkpoint_dir /home/nayan/.local/share/deepspeech/checkpoints/deepspeech-0.5.0-checkpoint --epochs 3 --train_files data/david/david.csv --dev_files data/david/david.csv --test_files data/david/david.csv --learning_rate 0.0001
Restoring from checkpoint failed. This is most likely due to a Variable name or other graph key that is missing from the checkpoint. Please ensure that you have not altered the graph expected based on the checkpoint. Original error:
Key cudnn_lstm/rnn/multi_rnn_cell/cell_0/cudnn_compatible_lstm_cell/bias not found in checkpoint
