h5py==3.0.0 causes issues with keras model #50

Closed JKamlah closed 3 years ago

JKamlah commented 3 years ago

It seems that the current version of h5py (3.0.0) causes issues, see: https://github.com/tensorflow/tensorflow/issues/44467 . A workaround, till an official fix is released, could be to specify h5py (e.g., ==2.10) in the requirements files. This problem also affects: https://github.com/qurator-spk/sbb_binarization

I have encountered the same problem:

Downgrading to h5py < 3 solves this.
