SystemError: Exception encountered when calling layer "ctc" (type Lambda). unknown opcode

[kyle-gonzales]

Hello,

I am trying to train the model with only 10 epochs. To test, I am using the last checkpoint saved in the weights folder during the training process. When I run test_on_iam(checkpoint="../weights/EASTER2--10--6.52.hdf5"), it says I have a SystemError from an unknown opcode.

Upon investigation, a lot of errors trace back to the python versions used to train and test the model. However, I am sure that I trained the model with same version I am using to test it. I have also read that it could be caused by the use of the lambda layer in the model. However, there aren't any apparent issues with the lambda layer.

Additionally, when I try to use your saved_checkpoint.hdf5, I also get an error when trying to load the model: ValueError: bad marshal data (unknown type code)

have you encountered this?

Hi,

I'm trying now to test this architecture and I'm facing the same issue. Did you find any solution?
