Hi, I have run the building commands, but when I run the first example training command the error shows like this. The KNN cuda 0.2 is installed. Could you please give me some advice?

Hi, sorry that i have no idea where goes wrong in your env. Try to check you have installed the package correctly.

I noticed that Ninja should also be installed, is that right?

if "Ninja is required to load C++ extensions"
you can try to run:
wget https://github.com/ninja-build/ninja/releases/download/v1.8.2/ninja-linux.zip
sudo unzip ninja-linux.zip -d /usr/local/bin/
sudo update-alternatives --install /usr/bin/ninja ninja /usr/local/bin/ninja 1 --force
