Environment

Operating System

Windows® 10 family

OpenVINO™ 2026.0 or later Python 3.8+

Description

Executed command ./downloader.py --all from model downloader directory
Yolo v3 model not found in expected directory location

Resolution

Note: The legacy Model Downloader is no longer available in OpenVINO™ 2026.0. Use this modern approach:

Step 1: Download YOLO v3 Model directly from the official source or GitHub repository.

Step 2: Convert and Use

import openvino as ov

# Convert model directly
model = ov.convert_model("yolov3.pt") # or yolov3.onnx
ov.save_model(model, "yolov3.xml")

# Or load directly without pre-conversion
core = ov.Core()
compiled_model = core.compile_model("yolov3.pt", "CPU")

Alternative: Search for pre-converted YOLO v3 models on Hugging Face or community repositories that are already OpenVINO™ compatible.

Additional information

The old two-step download and conversion process has been replaced by direct model conversion in latest releases.
