AttributeError: 'list' object has no attribute 'resize'

I know the right fomat should be "Boxlist", but I don't know how to cause this problems. I only rebuild the softNMS. HELP!

Try to use torchvision==0.2.1

[SkeletonOne]

Use torchvision==0.2.1 can solve this problem.

@XdpAreKid @SkeletonOne Thank you very much！It works！

@sunycl , changing to torchvision 0.2.1 throws the following error now

IndexError: list index out of range

[fmassa]

The problem is due to the fact that you are using a bad combination of maskrcnn-benchmark and torchvision, and has been fixed in https://github.com/facebookresearch/maskrcnn-benchmark/pull/744

[LIYHUI]

if I use torch1.4+cuda10.1+torchvision0.5 ,can I just turn torchvision==0.5 to torchvision==0.2.1? I'm worry about Their version adaptation problem。 @sunycl @fmassa

@LIYHUI I have the same configuration like you. I install torch1.4+cuda10.1+torchvision0.5. And I face the same problem of getting "'list' object has no attribute 'resize'".
Have you tried to replace torchvision0.5 with torchvision0.2? Did any wrong happen?
I am really looking forward to your reply. Thanks

@LIYHUI thanks for your fast reply. But your URL is expired. Could you please send me the URL another time. Thanks a lt!!!

首先这个问题出现是由于我下载的GitHub源码是别人的，不是Facebook官方的才导致。如果你也是从别人那下载的，很有可能别人改动了代码导致此bug。

解决方法：

定位：maskrcnn_benchmark/data/datasets/coco.py

line:66, 95, 96

self.transform 改为 self._transform

如果你的代码是 self._transform，那这里的情况可能不适用你，需要查找其他其原因
