this error is not easy to detect since tf.contrib is not stable. tf.layers.dense is the same with tf.contrib.layers.fully_connected as the later calls the former to create fully connected layers, see this question.

adding tf_config.gpu_options.allow_growth = True to avoid allocating all the memory of a GPU.
