Hi,

I think newer h5py solve this issue as the latest h5py seems to avoid your issue. See: https://github.com/h5py/h5py/blob/master/h5py/_hl/dataset.py#L76

I can confirm @maksak answer works...pip install h5py --upgrade did the trick for me.

I have the same problem, just open your file File "/home/vinay/chemistrytensor/local/lib/python2.7/site-packages/h5py/_hl/dataset.py", line 76 change the "-" to "~".

You can update your h5py file using this fix: https://github.com/h5py/h5py/commit/973c47f2fb70294ef0cba37a265360e7603f0528 I hope it works.
