it occurs when train fpn

I trian own data when I use voc data format. I use config which is resnet_v1_101_coco_trainval_fpn_dcn_end2end_ohem.yaml Log: append flipped images to roidb filtered 0 roidb entries: 33134 -> 33134 infer_shape error.

Hi，have you solved this problem ?

For Windows users, run cmd .\init.bat. For Linux user, run sh ./init.sh. The scripts will build cython module automatically and create some folders.Are you sure you read the installation instructions carefully?
