# phi-2-int8-ov |
|
|
|
* Model creator: [Microsoft](https://huggingface.co/microsoft) |
|
* Original model: [phi-2](https://huggingface.co/microsoft/phi-2) |
|
|
|
## Description |
|
|
|
This is [phi-2](https://huggingface.co/microsoft/phi-2) model converted to the [OpenVINO™ IR](https://docs.openvino.ai/2024/documentation/openvino-ir-format.html) (Intermediate Representation) format with weights compressed to INT8 by [NNCF](https://github.com/openvinotoolkit/nncf). |
|
|
|
## Quantization Parameters |
|
|
|
Weight compression was performed using `nncf.compress_weights` with the following parameters: |
|
|
|
* mode: **INT8_ASYM** |
|
|
|
For more information on quantization, check the [OpenVINO model optimization guide](https://docs.openvino.ai/2024/openvino-workflow/model-optimization-guide/weight-compression.html). |
|
|
|
## Compatibility |
|
|
|
The provided OpenVINO™ IR model is compatible with: |
|
|
|
* OpenVINO version 2024.1.0 and higher |
|
* Optimum Intel 1.16.0 and higher |
|
|
|
## Running Model Inference |
|
|
|
1. Install packages required for using [Optimum Intel](https://huggingface.co/docs/optimum/intel/index) integration with the OpenVINO backend: |
|
|
|
``` |
|
pip install optimum[openvino] |
|
``` |
|
|
|
2. Run model inference: |
|
|
|
``` |
|
from transformers import AutoTokenizer |
|
from optimum.intel.openvino import OVModelForCausalLM |
|
|
|
model_id = "https://huggingface.co/microsoft/phi-2" |
|
tokenizer = AutoTokenizer.from_pretrained(model_id) |
|
model = OVModelForCausalLM.from_pretrained(model_id) |
|
|
|
inputs = tokenizer("What is OpenVINO?", return_tensors="pt") |
|
|
|
outputs = model.generate(**inputs, max_length=200) |
|
text = tokenizer.batch_decode(outputs)[0] |
|
print(text) |
|
``` |
|
|
|
