Getting Errors while saving model in .h5 in pytorch and loading in .DL4J

1

I have a model in .h5 and I was able load it and evaluate in pytorch. But when I am trying to load the same .h5 in DL4J I am getting this error
HDF5-DIAG: Error detected in HDF5 (1.10.2) thread 0:

and this how I save and load the model.
torch.save(m,‘mod.h5’)
m = torch.load(‘mod.h5’)
m.eval()

Thanks

It looks like you are trying to load a model saved in PyTorch with a Java wrapper for Keras models.
Keras does not support loading PyTorch models, so you won’t be able to load it.

Note that the file type (.h5 in this case) is just the filename extension.

Thanks a lot for your reply.I was told that .h5 models can be used in DL4J.But its throwing an error.
