tf.GraphKeys.VARIABLES is deprecated

[mrry]

This question on Stack Overflow observes that using Pretty Tensor with the latest version of TensorFlow will lead to uninitialized variable errors. As far as I can tell, the problem stems from using tf.GraphKeys.VARIABLES as the default variable collection, which doesn't work with the (new) recommended way to initialize all variables (tf.global_variables_initializer().

Can you please update the implementation to use tf.GraphKeys.GLOBAL_VARIABLES, to match the default TensorFlow implementation, or suggest a workaround? Thanks!

Thanks for the bug, some of the changes in v0.12 were not backwards compatible and so I needed to cut a new release. Please reopen if the latest version in pypi doesn't work.
