Error pop outs when adjusting parameter in cfgs.py.

[chrischu83117]

Hi, recently I want to improve the result on my own dataset. Due to the reason that my result has many FP predicted bbox, so I try to adjust the parameter like show below:

1. FAST_RCNN_NMS_IOU_THRESHOLD = 0.5
   2.FAST_RCNN_IOU_POSITIVE_THRESHOLD = 0.8 3.FAST_RCNN_IOU_NEGATIVE_THRESHOLD = 0.5

When I was training , console popped out an error message:

2021-03-05 09:03:25.126176: F tensorflow/stream_executor/cuda/cuda_dnn.cc:430] could not convert BatchDescriptor {count: 0 feature_map_count: 512 spatial: 7 7 value_min: 0.000000 value_max: 0.000000 layout: BatchDepthYX} to cudnn tensor descriptor: CUDNN_STATUS_BAD_PARAM Aborted (core dumped)

Can someone tell me why,Thanks!
