描述

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.

研究方向
Examine the file train.py in the repository to identify where num max boxes is used as an input parameter and how it defines a tf.placeholder. Replace the placeholder shape with None (i.e., set shape=[None, ...] accordingly) and ensure the model training still functions correctly. Evaluate if removing the parameter affects training performance; if not, the parameter can be safely removed from the function signature and all calls.
