This error occurs when trying to load weights from an HDF5 file using the load_weights_from_hdf5_group_by_name function in Keras. The error message suggests that the attribute keras_version in the HDF5 file is of type str and does not have a decode method.

To fix this issue, you can modify the load_weights_from_hdf5_group_by_name function in the Keras source code. Locate the line that reads original_keras_version = f.attrs['keras_version'].decode('utf8') and change it to original_keras_version = str(f.attrs['keras_version']). This will convert the str attribute to a string before assigning it to original_keras_version.

After making this change, you can try loading the weights again
