Won't build h5py in Ubuntu 17

[wsanders]

While running "pip install -r requirements.txt". "pip install h5py" worked ok though...

The preproessor works OK but train.lua fails, can't find hdf5.h even though is it present in /usr/include/hdf5/serial/hdf5.h:

# th train.lua --input_h5 data/tiny-shakespeare.h5  --input_json data/tiny-shakespeare.json

Root cause is "share/lua/5.1/hdf5/ffi.lua:71: Unsupported HDF5 version: 1.10.0" .....

Having the same problem on OS X, no idea how to fix it yet

Having the same problem on OSX too...

I have created a fork (https://github.com/sharpie7/torch-rnn), and a pull request #215 which should help with this on Ubuntu 17.04. It may also work for OSX.
