Error loading history file (tf/keras 2.15)

[Regenhardt]

I trained some AI models (Conv->LSTM->Dense)on a linux server using the tensorflow:2.15 docker image. After training, I save the history like this:

history = model.fit(...)
with open(history_file, "wb") as f:  
    pickle.dump(history, f)

Then I download the files to my local windows computer and load them like this:

with open(history_file, "rb") as f:
    history = pickle.load(f)

Both use python 3.11. I already tried upgrading my local install, but it didn't work: tensorflow/tensorflow#74439

On pickle.load, I get the following error:

Error loading history file: 3c_128f_64f_32f_2l_100u_50u_without_implicit_adls_history Layer 'conv2d_3' expected 2 variables, but received 0 variables during loading. Expected: ['time_distributed_3/kernel:0', 'time_distributed_3/bias:0']

How do I fix this? I'd really like to load these histor files to add the data to my bachelor's thesis.

Other models worked, but there I only saved history.history, so that probably is part of the reason. I'd prefer not to have to retrain the models.

Hi @Regenhardt -

Thanks for reporting the issue. Can you provide the sample code of your model summary for helping in resolve the error ?
