I edit the D:\Anaconda\envs\torch1.8.2\lib\site-packages\torch\utils\cpp_extension.py"

the '['ninja', '-v']' in cpp_extension.py to '['ninja', '--version']'

A new error has occurred：

I checked the files in folder 'C:\Users\admin\Desktop\点云补全\SymmCompletion-main\extensions\KNN_CUDA\knn_cuda\csrc\_ext\knn and indeed there is no knn.pyd
