 If you don't have anaconda, you can get it from [here](https://www.anaconda.com/products/distribution).
 If you don't want anaconda, you can install PyTorch [any other way](https://pytorch.org/get-started/locally/).
 If you want to run models with 8-bit weights, please install **PyTorch with CUDA 11** or newer for compatility with [bitsandbytes](https://github.com/timDettmers/bitsandbytes).
