Describe the bug
Thanks for your excellent work!
I trained my own dataset using tridentnet. I converted my dataset to coco and ran create_coco_roidb.py , then changed gpus, num_class,log_frequency to 50,loader_worker to 4 in tridentnet_r101v2c4_c5_multiscale_addminival_3x_fp16.py. Do I need to change another parameters? I trained 10 epochs and used detection_test.py to validate. The results are bad.

Average Precision (AP) @[ IoU=0.50:0.95 | area= all | maxDets=100 ] = 0.000
Average Precision (AP) @[ IoU=0.50 | area= all | maxDets=100 ] = 0.001
Average Precision (AP) @[ IoU=0.75 | area= all | maxDets=100 ] = 0.000
Average Precision (AP) @[ IoU=0.50:0.95 | area= small | maxDets=100 ] = 0.000
Average Precision (AP) @[ IoU=0.50:0.95 | area=medium | maxDets=100 ] = 0.000
Average Precision (AP) @[ IoU=0.50:0.95 | area= large | maxDets=100 ] = 0.001
Average Recall (AR) @[ IoU=0.50:0.95 | area= all | maxDets= 1 ] = 0.028
Average Recall (AR) @[ IoU=0.50:0.95 | area= all | maxDets= 10 ] = 0.075
Average Recall (AR) @[ IoU=0.50:0.95 | area= all | maxDets=100 ] = 0.087
Average Recall (AR) @[ IoU=0.50:0.95 | area= small | maxDets=100 ] = 0.033
Average Recall (AR) @[ IoU=0.50:0.95 | area=medium | maxDets=100 ] = 0.072
Average Recall (AR) @[ IoU=0.50:0.95 | area= large | maxDets=100 ] = 0.092

    I recorded RpnL1,RcnnL1 and Lr during the training. Could you help me, thank you!
