复现faster-rcnn.pytorch-1.0测试自己的数据集时报错——已解决，随手记录
测试参考链接：Faster-RCNN.pytorch的搭建、使用过程详解（适配PyTorch 1.0以上版本）
运行python test_net.py --dataset pascal_voc --net res101 --checksession 1 --checkepoch 20 --checkpoint 463 --cuda时报错：

Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: '000001.xml'

如图：

解决方法：
修改lib\datasets\pascal_voc.py 291行左右，如图：

把{😒}.xml中的:s删掉，下同：
修改lib\datasets\voc_eval.py 120行左右，如图：

重新测试，成功

截个图意思一下

还好我没因为是YOLO就放弃参考哈哈哈哈哈！
