4 years past. I cannot built correct enviroments(my env: pytorch 1.7.1, cuda 11). when i install knn, show err:

I get the same error My env: python 3.9; pytorch 1.9; cu11.1

same error

Hi, the program was not tested on Windows. We recommend Linux.

AugustSteik commented 1 week ago

Hi all. I had run into the same issue when compiling on Windows (for reference I am using torch 1.7.1 with Cuda 10.1). The link errors caused by long definition can be solved by replacing all instances of long with int64_t* (note this needs the cstdint header). Also the error related to THCuda is because it was superseded by ATen so a few functions have to be redefined. Please see my meng-project fork for the adjusted source code: https://github.com/AugustSteik/graspnet-baseline/tree/meng-project/knn
