Awesome work, we are hiring

Hey Pavel

Awesome work, and I love to chat more and see if you are interested in working on chat bots. We're hiring talented developers like yourself to work on a revolutionary product on top of messaging platforms like FB Messenger, Viber, Kik, Telegram, etc.

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.

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 TensorFlow ops such as tf.cond to execute subgraphs conditioned on the value of a tensor.

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.
