An op outside of the function building code is being passed a "Graph" tensor. It is possible to have Graph tensors leak out of the function building context by including a tf.init_scope in your function building code. #9

I try to a new source

but i had this problem...

Traceback (most recent call last): File "/usr/local/lib/python3.6/dist-packages/tensorflow_core/python/eager/execute.py", line 61, in quick_execute num_outputs) TypeError: An op outside of the function building code is being passed a "Graph" tensor. It is possible to have Graph tensors leak out of the function building context by including a tf.init_scope in your function building code. For example, the following function will fail: @tf.function def has_init_scope(): my_constant = tf.constant(1.) with tf.init_scope(): added = my_constant * 2 The graph tensor has name: spec_lengths:0

During handling of the above exception, another exception occurred:

@kjh21212 Are you training on CPU or GPU? Also what is the rest of the error message? It should print out at the bottom which tensor it failed on.

Fixed by reverting to commit 53c7d92acfda671ba79a9a4e74cd127f04311e2c
