Cannot run torch train command – NYI stack traceback

[matthewclark4]

Hello, have been following the torch rnn mac install tutorial found here:
http://www.jeffreythompson.org/blog/2016/03/25/torch-rnn-mac-install/

I am running the following command for step 7. (using -gpu -1 flag because CUDA isnt working)

th train.lua -input_h5 data/tiny_shakespeare.h5 -input_json data/tiny_shakespeare.json -gpu -1
however it spits out this:

/Users/matthewclark/torch/install/bin/lua: .../matthewclark/torch/install/share/lua/5.2/hdf5/group.lua:88: NYI
stack traceback:

Any help would be much appreciated, am pretty stuck here
