resnet101-int8-ov

• Model creator: torchvision
• Original model: resnet101

Description

This is a torchvision version of resnet101 model converted to the OpenVINO™ IR (Intermediate Representation) format with weights compressed to INT8.

Quantization Parameters

Weight compression was performed using nncf.quantize with the following parameters:

• Quantization method: Post-Training Quantization (PTQ)
• Precision: INT8 for both weights and activations

For more information on quantization, check the OpenVINO model optimization guide.

Compatibility

The provided OpenVINO™ IR model is compatible with:

• OpenVINO version 2026.1.0 and higher
• Model API 0.4.0 and higher

Running Model Inference with Model API

1. Install required packages:

pip install openvino-model-api[huggingface]

<!-- markdownlint-disable MD029 -->

1. Run model inference:

import cv2
from model_api.models import Model
from model_api.visualizer import Visualizer

# 1. Load model
model = Model.from_pretrained("OpenVINO/resnet101-int8-ov")

# 2. Load image
image = cv2.imread("image.jpg")

# 3. Run inference
result = model(image)

# 4. Visualize and save results
vis = Visualizer().render(image, result)
cv2.imwrite("output.jpg", vis)

For more examples and possible optimizations, refer to the Model API Documentation.

Limitations

Check the original model implementation for limitations.
