'how to disable tensorflow do compute optimize for graph?
tensorflow version: 1.15.2
I got a model, and in graph, there is custom op which will save a file if it runs.
when I sess.run(the_last_op_tensor), it can return correctly.
but some custom ops are not be executed, because there no files are saved for these op.
if I sess.run(the_custom_op) then the file is saved.
I'm sure the output op is dependent on the custom op.
And if set
session_conf.graph_options.rewrite_options.disable_meta_optimizer = True
session_conf.graph_options.optimizer_options.opt_level = -1 # -1 is L0
some custom op that did not run before can be executed
So I guess tensorflow do some optimization before sess.run
What I want to know is, how to disable the optimization
