mAP is always -1

No matter how epoches I train is still -1.
It is like:

Average Precision (AP) @[ IoU=0.50:0.95 | area= all | maxDets= 20 ] = -1.000
Average Precision (AP) @[ IoU=0.50 | area= all | maxDets= 20 ] = -1.000
Average Precision (AP) @[ IoU=0.75 | area= all | maxDets= 20 ] = -1.000
Average Precision (AP) @[ IoU=0.50:0.95 | area=medium | maxDets= 20 ] = -1.000
Average Precision (AP) @[ IoU=0.50:0.95 | area= large | maxDets= 20 ] = -1.000
Average Recall (AR) @[ IoU=0.50:0.95 | area= all | maxDets= 20 ] = -1.000
Average Recall (AR) @[ IoU=0.50 | area= all | maxDets= 20 ] = -1.000
Average Recall (AR) @[ IoU=0.75 | area= all | maxDets= 20 ] = -1.000
