UnicodeDecodeError

[myblogvue]

是我下载训练的json文件有错吗，读取person_keypoints_trainvalminusminival2014.json文件就会出错，但是读取person_keypoints_minival2014.json不会出错。出现提示：

coco = COCO('/home/home_data/cxp/code/tf-cpn/data/COCO/MSCOCO/annotations/person_keypoints_trainvalminusminival2014.json')
loading annotations into memory...
