Error using Torch RNN
Check that the header file exists and that you have the correct path. 
If the header file is missing you skipped the preprocess step. If the header file exists it's likely in your data directory and not in the same directory as the sample.lua code:
th train.lua -input_h5 data/my_data.h5 -input_json data/my_data.json
I'm following the instructions on github.com/jcjohnson/torch-rnn and have it working until the training section. When I use th train.lua -input_h5 my_data.h5 -input_json my_data.jsonI get the error Error: unable to locate HDF5 header file at /usr/local/Cellar/hdf5/1.10.0-patch1/include;/usr/include;/usr/local/opt/szip/include/hdf5.h

I'm new to luarocks and torch, so I'm not sure what's wrong. I installed torch-hd5f. Any advice would be very much appreciated.
