Failed to enable custom CUDA kernel

[Firepal]

after running "install-py-dep.bat" and trying to run GPU-4G-3B-World

"Failed to switch model - Failed to enable custom CUDA kernel, ninja is required to load C++ extensions. You may be using the CPU version of PyTorch, please reinstall PyTorch with CUDA. Or if you are using a custom Python interpreter, you must compile the CUDA kernel by yourself or disable Custom CUDA kernel acceleration"

you need to confirm that CUDA and pytorch are installed on your computer

Are you using Python 3.10? The precompiled kernel in the software is only available in Python 3.10.
