Installing cuda, cannot find ninja + cannot find file.

[jonplumb42]

Hey there. I'm trying to install, following the steps here: https://aituts.com/llama/ I've gotten to Step 3, which says to do the following:

mkdir repositories
cd repositories
git clone https://github.com/qwopqwop200/GPTQ-for-LLaMa
cd GPTQ-for-LLaMa
python setup_cuda.py install

But I get the following errors. First, it says it can't find "ninja," which seems alright because it uses an alternative and continues. But then it says it can't find a specified file in my ProgramData folder. But I've verified it's there...

Line 359 of the cpp_extension.py says: warnings.warn(f'Error checking compiler version for {compiler}: {error}')

Any thoughts?
