Installation

[RuiyuM]

Dear author,

I find that during installation the sparsehash even with the correct configuration it still cannot installed at target sphash/ dir intead it will always installed at current sparsehash dir.
And when I try to run the code pip install ./torchsparse it showed:
cuda mismatches and my system cuda is 12.0 but I have installed the 11.3 cuda at conda.

thanks for your time.
