THC/THC.h doesn't exist

[AinaraC]

Hi!

I'm trying to run a model on a Jetson Orin with CUDA 12.6 and PyTorch 2.5.0, but it seems like the THC library doesn't exist anymore. I really need to run the model with these versions because my Jetson doesn't support earlier versions.

If anyone is facing this problem, I would be very grateful for your help.

In later versions of PyTorch, the THC library has been replaced by ATen.

I've found the solution on the OpenPCDet official repository. Some of the pcdet/ops scripts have been updated in this repository, so you can download them directly from there.

According to this issue, for the remaining scripts, you can remove the following lines:

#include THC/THC.h
extern THCState *state;

It works fine for me.

After torch1.11, THC was removed
