I met the same problem. Did you fix it?

看起来像是dataloader有问题，请帖上更多代码或者自己查查看。

检查一下checkpoint和图片路径是否正确，把num_worker设置成0试试

同样的问题已经解决.
搜索的是docker引起的莫名其妙的错误. 可能是我用的集群分给给每个用户是docker虚拟出来的 解决方法： https://github.com/whai362/PSENet/blob/4d95395658662f2223805c36dcd573d9e190ce26/train.py#L158 改为 num_workers=0

运行后出现另外一个新错误. UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 0: ordinal not in range(128) 卸载旧版本mmcv，安装最新版本的mmcv即可 pip uninstall mmcv pip install mmcv

解决完后，就能正常运行了..然后把num_worker改为gpu_num整数倍也没问题了
