Please help, a lot of thanks.

This solves.

thanks @Da1sypetals for reporting build issues, and finding a solution 👍 (using an older g++ version)

my current versions (where it compiles fine) :

g++ --version
g++ (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0

nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2023 NVIDIA Corporation
Built on Mon_Apr__3_17:16:06_PDT_2023
Cuda compilation tools, release 12.1, V12.1.105
Build cuda_12.1.r12.1/compiler.32688072_0

import torch as th
>>> th.__version__
'2.2.1+cu121'

I'll leave a note on the Readme.txt to use older g++ version while thinking for a more long term solution.
