train the belief tracker

[yahuvi]

I use default config and run the tracker training on macOS:
python nndial.py -config config/tracker.cfg -mode train

Theano is very slow in compiling computational graphs for this model because the architecture is non-trivial. You can put theano flags optimizer=fast_compile to run it. The run-time is relatively faster because both the model and dataset are small.

THEANO_FLAGS=optimizer=fast_compile,device=gpu,floatX=float32 python nndial.py -config config/tracker.cfg -mode train

Found the example_run, sorry!

I came to the same problem.
The program starts to train by suppling THEANO_FLAGS="optimizer=fast_compile".
