rbm example problems about deepnet

[nitishsrivastava]

Hello pliz,
To fix the first problem - make sure cudamat is on your LD_LIBRARY_PATH. See INSTALL.txt for more details.
It is failing on data import because it can't find the data. Did you download the data and run setup_examples.py ? If not, see INSTALL.txt for how to do this.

Thanks Nitish! cudamat is on my path as I said if I run python anywhere else and just import cudamat - works smoothly, which does not solve the problem.
With the second issue - I've resolved it by looking into mnist.pbtxt and observing relative paths there, but relative to the examples directory. After changing the relative path to the absolute path - I can run the example (using my trainer.py copy method rather than your runall.sh) and it works (well, still running).

Thanks!

So I've figured out the problems:

1. Before reading INSTALL.txt I've shadowed cudamat.py with a different file in the deepnet directory. Removing it - solved the first problem.

2. When running setup_examples.py I gave the script relative paths :) That created problems in issue 2. An easy fix would be:
   
diff --git a/deepnet/examples/setup_examples.py b/deepnet/examples/setup_examples.py
index e23fee5..136ba43 100644
--- a/deepnet/examples/setup_examples.py

   Thanks!

Thanks for the suggestion. I have added abspath in a new commit.
