如果模型太大无法加载怎么办?

There are several solutions to use The XXL versions of ProtT5:

1. Use a GPU with a big memory like NVIDIA Quadro RTX-8000 or NVIDIA A100, with/without half-precision.
2. Use a GPU with less memory after you quantize the model, which will make the model size 3x-4x smaller:
   https://pytorch.org/docs/stable/quantization.html
3. Convert the model to onnx, then Quantize the model, and use the CPU rather than GPU for inference:

4. Parallelize the model across multiple small GPUs:

You can, of course, combine one or more of the above points.
