要训练的数据集放在项目下的dataset/coco下，指定训练集路径后会下载coco的train2017不知为何原因，后看终端提示try searching /Users/shuxsu/.cache/paddle/dataset or downloading dataset...，将数据集拷贝至/Users/shuxsu/.cache/paddle/dataset/coco下 再次运行不再下载，并且终端提示 found annotations/instance_train.json 等。后控制台报错： 2019-10-11 12:58:43,488-WARNING: fail to map op [DecodeImage_348189] with error: [Errno 21] Is a directory: '/Users/shuxsu/Downloads/models-develop/PaddleCV/PaddleDetection/dataset/coco/train2017/' and stack: Traceback (most recent call last): File "/Users/shuxsu/Downloads/models-develop/PaddleCV/PaddleDetection/ppdet/data/transform/init.py", line 77, in _mapper out = f(sample, ctx) File "/Users/shuxsu/Downloads/models-develop/PaddleCV/PaddleDetection/ppdet/data/transform/operators.py", line 99, in call with open(sample['im_file'], 'rb') as f: IsADirectoryError: [Errno 21] Is a directory: '/Users/shuxsu/Downloads/models-develop/PaddleCV/PaddleDetection/dataset/coco/train2017/'
