Environment:
GPU : RTX 8000
CUDA: 10.0
Pytorch 1.0.1

Question:

If i use RTX 8000 CUDA 10.0 on the above software environment, I am getting error " AttributeError: module ‘torch.cuda’ has no attribute ‘amp’ "

What is the issue? How can i solve it?

请问您解决了吗?我也遇到了这个问题，查出来的结果是torch版本应该改在1.4.0以上，但是作者给出的torch需要1.0，请问您最后问题解决了吗？

Were you able to solve it @suresh-s?
To resolve this #1236 I installed Pytorch 1.4 but now facing "module ‘torch.cuda’ has no attribute ‘amp’" issue. To resolve the latter issue the PyTorch version should be greater than 1.6. Not sure what is the correct solution.

安装的 pytorch 1.7.0可以解决 好像1.6以上都可以

不知道为什么作者要求1.0哎 但是确实是提高版本解决的 我今天跑的时候发现1.7在绘制可视化结果的时候有点问题 现在改成了1.6版本的

1.7版本在导入maskrcnn_benckmark时，from maskrcnn_benchmark import _C 会遇到错误？
