我正在使用下面的命令开始深度语音模型的训练
%cd /content/DeepSpeech
!python3 DeepSpeech.py
--drop_source_layers 2 --scorer /content/DeepSpeech/data/lm/kenlm-nigerian.scorer
--train_cudnn True --early_stop True --es_epochs 6 --n_hidden 2048 --epochs 5
--export_dir /content/models/ --checkpoint_dir /content/model_checkpoints/
--train_files /content/train.csv --dev_files /content/dev.csv --test_files /content/test.csv
--learning_rate 0.0001 --train_batch_size 64 --test_batch_size 32 --dev_batch_size 32 --export_file_name 'he_model_5'
--max_to_keep 3
我一直得到以下错误一次又一次。
(0) Invalid argument: Not enough time for target transition sequence (required: 28, available: 24)0You can turn this error into a warning by using the flag ignore_longer_outputs_than_inputs
(1) Invalid argument: Not enough time for target transition sequence (required: 28, available: 24)0You can turn this error into a warning by using the flag ignore_longer_outputs_than_inputs
以下方法对我有效
去DeepSpeech/training/deepspeech_training/train.py
现在查找以下特定行(通常在240-250)
total_loss = tfv1.nn.ctc_loss(labels=batch_y, inputs=logits, sequence_length=batch_seq_len)
改成如下
total_loss = tfv1.nn.ctc_loss(labels=batch_y, inputs=logits, sequence_length=batch_seq_len, )
