Changed if conditions on tf.Tensor objects.

Those conditions caused error:

TypeError: Using a `tf.Tensor` as a Python `bool` is not allowed. Use `if t is not None:` instead of `if t:` to test if a tensor is defined, and use the logical TensorFlow ops to test the value of a tensor.

On my OS X El Capitan, Python 2.7.11, Anaconda 4.0.0 and Tensorflow 0.8.0. With those fixes I was able to run a model.

i don't exactly know why i am facing this error.any solutions to it.

Test on B/W images

Does, anyone have any clue, or is there any script, so as how to test the trained model? It would be quite nice to try it on few B/W images.
