CLIP model with Jina CLIP and OpenVINO#

This Jupyter notebook can be launched after a local installation only.

Github

jina-clip-v1 is a state-of-the-art English multimodal(text-image) embedding model trained by Jina AI. It bridges the gap between traditional text embedding models, which excel in text-to-text retrieval but are incapable of cross-modal tasks, and models that effectively align image and text embeddings but are not optimized for text-to-text retrieval. jina-clip-v1 offers robust performance in both domains. Its dual capability makes it an excellent tool for multimodal retrieval-augmented generation (MuRAG) applications, allowing seamless text-to-text and text-to-image searches within a single model. jina-clip-v1 can be used for a variety of multimodal applications, such as: image search by describing them in text, multimodal question answering, multimodal content generation. Jina AI has also provided the Embeddings API as an easy-to-use interface for working with jina-clip-v1 and their other embedding models.

In this notebook we will load the model with Hugging Face Transformers, convert it to OpenVINO IR format, optimize it with NNCF and show the life demo.

Instantiate model#

Let’s load the jinaai/jina-clip-v1 with Hugging Face Transformers. We creates PyTorch model class instance with AutoModel, load and initialize it with model configuration and weights, using from_pretrained method.

Convert Model to OpenVINO IR format#

OpenVINO supports PyTorch models via conversion to OpenVINO Intermediate Representation (IR). OpenVINO model conversion API should be used for these purposes. ov.convert_model function accepts original PyTorch model instance and example input for tracing and returns ov.Model representing this model in OpenVINO framework. Converted model can be used for saving on disk using ov.save_model function or directly loading on device using core.complie_model.

Quantize model to INT8 using NNCF#

Lets speed up the model by applying 8-bit post-training quantization from NNCF (Neural Network Compression Framework) and infer quantized model via OpenVINO™ Toolkit. NNCF enables post-training quantization by adding quantization layers into model graph and then using a subset of the training dataset to initialize the parameters of these additional quantization layers. Quantized operations are executed in INT8 instead of FP32/FP16 making model inference faster. The optimization process contains the following steps:

  1. Prepare quantization dataset

  2. Quantize the converted OpenVINO model with NNCF with nncf.quantize().

  3. Save the INT8 model using openvino.save_model() function.

  4. Compare model size of converted and quantized models.

  5. Compare performance of converted and quantized models.

Note: quantization process may require additional time and memory for performing. You can disable it using widget below:

to_quantize = widgets.Checkbox(
    value=True,
    description="Quantization",
    disabled=False,
)

Compare inference time of the FP16 IR and quantized models#

To measure the inference performance of the FP16 and INT8 models, we use median inference time on calibration dataset. So we can approximately estimate the speed up of the dynamic quantized models.

NOTE: For the most accurate performance estimation, it is recommended to run benchmark_app in a terminal/command prompt after closing other applications with static shapes.
