question:
tensorflow loading ckpt error
Reason here:
The tensorflow version corresponding to the ckpt file is too old, and some of the built-in variable names have changed.
hint:
Key lstm_o/bidirectional_rnn/bw/lstm_cell/biases not found in checkpoint
Error:
Use the checkpoint_convert.py given by github's official tensorflow to upgrade the ckpt version:
python checkpoint_convert.py '/path/to/checkpoint/model.ckpt' '/path/to/new_checkpoint/model.ckpt'
