I can't compile those three files

My environment is：
cuda 10.1
pytorch 1.7

I can't compile the following three files

What is the configuration of your environment？

@libingDY You may find the env config in https://github.com/poodarchu/Det3D/blob/master/INSTALLATION.md

For my env, the cuda 10.1 and pytorch 1.4.0 is fine, but I have not used so high version of pytorch as 1.7.

Thank you very much for your reply. I have changed the version of torch, but I have encountered the following problems：

@libingDY It seems an issue of apex, you may also need to reinstall it after updating your pytorch version.

@Vegeta2020 My environment is the cuda 10.1 and pytorch 1.4.0, And I meet "AttributeError: module 'torch.cuda' has no attribute 'amp'" problem, should I update my torch version? But high version torch will meet build problem like #22 . So which version is right?

请问这个问题解决了吗？我也遇到了同样的问题，我的环境是cuda10.0和pytorch1.1.0，尝试升级pytorch1.7也会带来其他问题。

@LiuPearl1 have you solved it?I meet the same question which puzzled me long time.
