我也遇到了，是预测推理阶段

解决了吗

[kitterive]

同样问题，有解决的吗

[yistiger]

已解决，到PaddleDetection/ppdet/data/transform/operators.py，原代码：with open(sample['im_file'], 'rb') as f:

sample['image'] = f.read() 改为 sample['image'] = cv2.imread(sample['im_file'])

        打印sample print("image",sample["image"])
         print(sample)，会发现有image是为None的，把None的图片在数据集、标注文件删除掉就可以了

那可能还是有不一样的问题，你说的那个我其实试了的，直接cv2.imread(sample['im_file'])读出来每个都是None，然后fread其实内存读到了同样大的数据，就是无法解码。最后我用docker环境了，我实在不知道是啥问题导致的，这段代码甚至单独拎出来都能成功读取到图片。
