DEPLOY_TEXT = f""" Having table full of powerful models is nice and call but at the end of the day, you have to be able to use them for something. Below you will find sample code to help you load models and perform inference. ## Inference with Gaudi 2 Habana's SDK, Intel Gaudi Software, supports PyTorch and DeepSpeed for accelerating LLM training and inference. The Intel Gaudi Software graph compiler will optimize the execution of the operations accumulated in the graph (e.g. operator fusion, data layout management, parallelization, pipelining and memory management, and graph-level optimizations). Optimum Habana provides covenient functionality for various tasks, below you'll find the command line snippet that you would run to perform inference on Gaudi with meta-llama/Llama-2-7b-hf. The "run_generation.py" script below can be found [here](https://github.com/huggingface/optimum-habana/tree/main/examples/text-generation) ```bash python run_generation.py \ --model_name_or_path meta-llama/Llama-2-7b-hf \ --use_hpu_graphs \ --use_kv_cache \ --max_new_tokens 100 \ --do_sample \ --batch_size 2 \ --prompt "Hello world" "How are you?" ``` # Inference Intel Extension for Transformers Intel® Extension for Transformers is an innovative toolkit designed to accelerate GenAI/LLM everywhere with the optimal performance of Transformer-based models on various Intel platforms, including Intel Gaudi2, Intel CPU, and Intel GPU. ### INT4 Inference (CPU) ```python from transformers import AutoTokenizer from intel_extension_for_transformers.transformers import AutoModelForCausalLM model_name = "Intel/neural-chat-7b-v3-1" prompt = "When winter becomes spring, the flowers..." tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True) inputs = tokenizer(prompt, return_tensors="pt").input_ids model = AutoModelForCausalLM.from_pretrained(model_name, load_in_4bit=True) outputs = model.generate(inputs) ``` ### INT4 Inference (GPU) ```python import intel_extension_for_pytorch as ipex from intel_extension_for_transformers.transformers.modeling import AutoModelForCausalLM from transformers import AutoTokenizer device_map = "xpu" model_name ="Qwen/Qwen-7B" tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True) prompt = "When winter becomes spring, the flowers..." inputs = tokenizer(prompt, return_tensors="pt").input_ids.to(device_map) model = AutoModelForCausalLM.from_pretrained(model_name, trust_remote_code=True, device_map=device_map, load_in_4bit=True) model = ipex.optimize_transformers(model, inplace=True, dtype=torch.float16, woq=True, device=device_map) output = model.generate(inputs) ``` # Intel Extension for PyTorch Intel® Extension for PyTorch extends PyTorch with up-to-date features optimizations for an extra performance boost on Intel hardware. Optimizations take advantage of Intel® Advanced Vector Extensions 512 (Intel® AVX-512) Vector Neural Network Instructions (VNNI) and Intel® Advanced Matrix Extensions (Intel® AMX) on Intel CPUs as well as Intel Xe Matrix Extensions (XMX) AI engines on Intel discrete GPUs. Moreover, Intel® Extension for PyTorch* provides easy GPU acceleration for Intel discrete GPUs through the PyTorch* xpu device. There are a few flavors of PyTorch that can be leveraged for inference.
