Hi, when I execute the command:

sh make.sh

I got errors:

error: command 'gcc' failed with exit status 1

Can someone tell me how can I fix this problem?

@ouening Using pytorch 0.3.1 will fix this.

Yeah I know downgrading to 0.4 can fix it , but it's not the best solution. I think we should modify the file build.py in lib/model/nms,lib/model/roi-align and so on. From the solution in https://blog.csdn.net/ShuqiaoS/article/details/88420326 : change from torch.utils.ffi import create_extension to from torch.utils.cpp_extension import BuildExtension and change ffi = create_extension(...) to ffi = BuildExtension(...)

but other errors happened! I have no knowledge of cuda ,pytorch extension and write a build file, so hope someone can fix this problem

Is there someone who fixed this???
