Freeing buffers strange behavior
# Description:
# This script is a minimal example of a freeing buffer strange behavior. Originally it contains error diagnosed
# by PyTorch:
# "RuntimeError: Trying to backward through the graph a second time, but the buffers have already been freed.
# Specify retain_graph=True when calling backward the first time."
# One can find statements which can be changed to remove error.
