A Problem : CUDA/limits.cuh(119): error: identifier "inf" is undefined

hi, I have some trouble when i install softpool. The detail is that im follow "Installation" and use "make install",then im encountered the mistake:

The problem was solved by install pytorch==1.7

Hi @alexandrosstergiou , I also meet this issue with torch 1.13.0 + cu117, but I found a solution in a chinese blog.

Let me briefly summarize.
Because the error is CUDA/limits.cuh(119): error: identifier "inf" is undefined.
It seems that the variable or macro is not defined, so hw refer to other articles to define the integer inf after the include directive and assign the value to a large number:
const int inf=0x3f3f3f3f.
I tried this scheme, and make test can pass

Hi @MaxChanger ,

Thanks for narrowing down the cause of the error. It seems that this is due to inf not being loaded from CUDA Math in limits.cuh . I will run some tests to see if there are any effects by defining a constant explicitly (e.g. const int inf=0x3f3f3f3f), and if not, I'll update limits.cuh afterward.
