Thank you very much for this very useful tool! Appreciate it.
I was able to successful install, and run on windows 11 with Miniconda3.

Steps:
conda create -n mmaudio python=3.9
conda activate mmaudio
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118 --upgrade
git clone your repo
cd MMAudio
pip install -e .
python gradio_demo.py

Works amazing.
Keep the good work!
