Hi,

I'm getting error when i send multiple request to tensorflow keras module.

Error:

File "/usr/lib/python2.7/dist-packages/tensorflow/python/keras/backend.py", line 3289, in call
self._make_callable(feed_arrays, feed_symbols, symbol_vals, session)
File "/usr/lib/python2.7/dist-packages/tensorflow/python/keras/backend.py", line 3222, in _make_callable
callable_fn = session._make_callable_from_options(callable_opts)
File "/usr/lib/python2.7/dist-packages/tensorflow/python/client/session.py", line 1489, in _make_callable_from_options
return BaseSession._Callable(self, callable_options)
File "/usr/lib/python2.7/dist-packages/tensorflow/python/client/session.py", line 1446, in init
session._session, options_ptr)

InvalidArgumentError: Tensor add_17:0, specified in either feed_devices or fetch_devices was not found in the Graph

Please suggest.
