Prettytensor not working with TF1.8

[YutingZhang]

After upgrading to TF1.8, prettytensor stopped working with the following error. It seems _VARSCOPE_KEY is removed from variable_scope.

.../lib/python3.6/site-packages/prettytensor/scopes.py in var_and_name_scope(names)
53 full_name = var_scope.name
54
---> 55 vs_key = tf.get_collection_ref(variable_scope._VARSCOPE_KEY)
56 try:
57 # TODO(eiderman): Remove this hack or fix the full file.

AttributeError: module 'tensorflow.python.ops.variable_scope' has no attribute '_VARSCOPE_KEY'

@YutingZhang Did you find the fix for this issue ?

[YutingZhang]

@Saahiljeet-Singh I have not looked into this issue. Instead, I simply downgraded TF to 1.7 ...

Change
tf.get_collection_ref(variable_scope._VARSCOPE_KEY) --> tf.get_collection_ref(variable_scope._VARSCOPESTORE_KEY)

Change tf.get_collection_ref(variable_scope._VARSCOPE_KEY) --> tf.get_collection_ref(variable_scope._VARSCOPESTORE_KEY)

After the change, the error is still reported
