placeholder error

[zhongboyin]

Thanks for your sharing, I download your code and running. But there is an error as follows:

lib/python2.7/site-packages/tensorflow/python/framework/ops.py", line 1470, in init self._traceback = self._graph._extract_stack() # pylint: disable=protected-access

InvalidArgumentError (see above for traceback): You must feed a value for placeholder tensor 'dropout_1/keras_learning_phase' with dtype bool [[Node: dropout_1/keras_learning_phase = Placeholderdtype=DT_BOOL, shape=, _device="/job:localhost/replica:0/task:0/device:CPU:0"]]

Have you ever encounter this error?

Is it a error due to the version of tensorflow ? What's your tensorflow version?
