Error during run

[ElenSmi]

I can't seem to understand the error I am getting while running the main.py

Use tf.global_variables_initializer instead.

What is your TensorFlow and TensorLayer version?

[jkraybill]

I had this error; I was using a non-GPU build of Tensorflow. Make sure you install tensorflow-gpu or use a build with GPU support.
