fatal error: THC/THC.h: No such file or directory

See original GitHub issue

I got this error when I followed the installation instructions. Everything worked well until pip install -v -e . It eventually raised error:

 ...
cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++
    mmdet3d/ops/ball_query/src/ball_query.cpp:4:10: fatal error: THC/THC.h: No such file or directory

              ^~~~~~~~~~~
    compilation terminated.

Could someone please tell me how to solve this?

Yes, it seems that the TH/THC include files have been removed in the latest pytorch version. mmdet3d still has to be adjusted to these changes, I guess.

I just solved this problem by reinstalling pytorch. I’ve tried to downgrade gcc, reinstall mmdet3d, had double checked mmcv version and did git checkout dev for mmdet3d but none of them seemed to work.

I referenced an answer on https://discuss.pytorch.org/t/question-about-thc-thc-h/147145. It seems that it would automatically install latest version if you follow the instructions on pytorch website and it could be inadaptable with the environment. I reinstalled pytorch to 1.6 and could successfully install mmdet3d.

Thanks a lot anyway.
