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_...
bnb_config = BitsAndBytesConfig( load_in_4bit=True, bnb_4bit_quant_type="nf4", bnb_4bit_compute_dtype=torch.bfloat16 ) model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto", quantization_config=bnb_config) Expected behavior when i am running the above snipped it is...

{iizuka, nakura}@vdec.u-tokyo.ac.jp, {tohge, asada}@silicon.u-tokyo.ac.jp Abstract—This paper proposes a reference-clock-less burst- mode CDR that resumes from a stand-by state just after a 4-bit preamble utilizing a cycle-lock gated-oscillator based on self-tunable digitally-...
