import_meta_graph:KeyError, no InUse

 

 

I think this is a general problem with ops defined in the tf.contrib namespace, because they are lazily registered on the first use of any tf.contrib module. If you add the statement dir(tf.contrib) (or something else that uses tf.contrib) before calling tf.train.import_meta_graph(), it should work.
