torch 1.7 in google colab

[bahramreza]

Hello . I wanted to run Fairmot code in google colab but I could not install torch1.7 in colab. And I see the following error. Is it possible to give advice?
/content/FairMOT/DCNv2/DCNv2/src/cpu/dcn_v2_cpu.cpp:7:10: fatal error: TH/TH.h: No such file or directory
7 | #include <TH/TH.h>
| ^~~~~~~~~
compilation terminated.

Hi, did you get it to work? I'm having the same issue, and even when I roll back Python to version 3.7 as suggested, it still doesn't work.
