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. For detailed documentation,
the visit https://intel.github.io/intel-extension-for-pytorch/#introduction
### IPEX with Optimum Intel (no quantization)
Requires installing/updating optimum `pip install --upgrade-strategy eager optimum[ipex]
`
```python
from optimum.intel import IPEXModelForCausalLM
from transformers import AutoTokenizer, pipeline
model = IPEXModelForCausalLM.from_pretrained(model_id)
tokenizer = AutoTokenizer.from_pretrained(model_id)
pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)
results = pipe("A fisherman at sea...")
```
### IPEX with Stock PyTorch with Mixed Precision
```python
import torch
import intel_extension_for_pytorch as ipex
import transformers
model= transformers.AutoModelForCausalLM(model_name_or_path).eval()
dtype = torch.float # or torch.bfloat16
model = ipex.llm.optimize(model, dtype=dtype)
# generation inference loop
with torch.inference_mode():
model.generate()
```
# OpenVINO Toolkit
```python
from optimum.intel import OVModelForCausalLM
from transformers import AutoTokenizer, pipeline
model_id = "helenai/gpt2-ov"
model = OVModelForCausalLM.from_pretrained(model_id)
tokenizer = AutoTokenizer.from_pretrained(model_id)
pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)
pipe("In the spring, beautiful flowers bloom...")
```
