UserWarning: Error checking compiler version for cl:

[DioMou]

I am having problems with setup the dcnv2, it gives me the following warning if I run python setup.py build develop. Although the building process successfully finished, but if I try to import _ext, it says DLL load failed while importing _ext, so I suspect this is because of the user warning below.
running build
running build_ext
cl(it says this is my printed compiler name but I am not running it on visual studio, this is simply vscode with python 3.8 torch 3.7.0)
