No matching distribution found for onnxruntime-gpu>=1.16.0 when installing Pyannote from GitHub

Question

I need to install Pyannote-audio for a project and its requirements (requirements.txt) include onnxruntime-gpu v1.16.0 or higher but I can't install it. GitHub link to the package: https://github.com/pyannote/pyannote-audio

I read somewhere that onnxruntime (not onnxruntime-gpu) works on Python<3.10 so I installed pyenv to switch to 3.9 but changing the version did not make a difference. I tried installing it with pip, pip3 and conda. Conda only had onnxruntime, NOT onnxruntime-gpu. I can install onnxruntime, but Pyannote won't work without onnxruntime-gpu.
