Key cnn_lstm/B not found in checkpoint

[chreul]

self._traceback = tf_stack.extract_stack()

NotFoundError (see above for traceback): 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 cnn_lstm/B not found in checkpoint
[[{{node save_1/RestoreV2}} = RestoreV2[dtypes=[DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT], _device="/job:localhost/replica:0/task:0/device:CPU:0"](_arg_save_1/Const_0_0, save_1/RestoreV2/tensor_names, save_1/RestoreV2/shape_and_slices)]]

how can I solve this problem?

@hsl20130659 please perform a dry run (--dry_run) and post (part of) the output.

It looks like the model needs an upgrade as described here. I get a similar error Key B not found in checkpoint, but the instructions refer to a script calamari_ocr/scripts/tensorflow_rename_variables.py which is not part of the code.

@stweil If you use calamari<=0.1.8 you can not use the current models of the model repository, you need to 'downgrade' them or simply access an older commit or even here.
The upgrade script is available in the current Calamari version.
