The quality of the 4-bit quantization is really abysmal compared to both non-quantized models and GPTQ quantization (https://github.com/qwopqwop200/GPTQ-for-LLaMa). Wouldn't it make sense for llama.cpp to load
Chapter 4 Bit efficient quantization - ScienceDirectThis chapter has introduced quantization methods and how to efficiently exploit bit resources to optimize coding of vectors of data containing components with different statistical properties. In the theory of this chapter we have not directly related ...

Creating a separate issue for workarounds to huggingface/transformers#23904 I understand that models loaded in 4 bit cannot be directly saved. It also appears not straightforward to convert them back to a higher precision data type (I ge...

为了缓解在极低位(2位、3位、4位)量化中常见的这些性能下降问题,我们提议采用一种通用的非对称量化方案,该方案带有可学习的偏移参数以及可学习的缩放参数。我们表明,所提出的量化方案能针对不同层以不同方式学习适应负激活值,并恢复LSQ所造成的准确率损失,例如,在对EfficientNet - B0进行W4A4量化时,比LSQ的准确率...

I tryed to modify your example code to run this model on lowvram card by BNB 4bit or 8bit quantization config. While use bnb 4bit config like below: qnt_config = BitsAndBytesConfig(load_in_4bit=True, bnb_4bit_quant_type="nf4", bnb_4bit_compute_dtype=torch.float16, bnb_4bit_...
