Description

object detection network receives num_max_boxes parameter, but might be possible to remove.

num_max_boxes is used to create an instance of tf.placeholder. However, it is possible to use None for tf.placeholder if the tensor shape is not fixed. If training performance is not decreased, we can remove this parameter.

Contributor guide

Research direction
Study the usage of `num max boxes` in train.py and related files. Understand how `tf.placeholder` is used with this parameter. Consider replacing it with `None` and test for any performance degradation. Verify that the object detection network handles variable input sizes correctly after the change.
