👋 Hello @slience-ops, thank you for your interest in YOLOv5 🚀! Please visit our ⭐️ Tutorials to get started, where you can find quickstart guides for simple tasks like Custom Data Training all the way to advanced concepts like Hyperparameter Evolution.

If this is a 🐛 Bug Report, please provide screenshots and minimum viable code to reproduce your issue, otherwise we can not help you.

If this is a custom training ❓ Question, please provide as much information as possible, including dataset images, training logs, screenshots, and a public link to online W&B logging if available.

For business inquiries or professional support requests please visit https://ultralytics.com or email [email protected].

Requirements

Python>=3.7.0 with all requirements.txt installed including PyTorch>=1.7. To get started:

git clone https://github.com/ultralytics/yolov5  # clone
cd yolov5
pip install -r requirements.txt  # install

Environments

YOLOv5 may be run in any of the following up-to-date verified environments (with all dependencies including CUDA/CUDNN, Python and PyTorch preinstalled):

• Google Colab and Kaggle notebooks with free GPU:
• Google Cloud Deep Learning VM. See GCP Quickstart Guide
• Amazon Deep Learning AMI. See AWS Quickstart Guide
• Docker Image. See Docker Quickstart Guide

Status

If this badge is green, all YOLOv5 GitHub Actions Continuous Integration (CI) tests are currently passing. CI tests verify correct operation of YOLOv5 training (train.py), validation (val.py), inference (detect.py) and export (export.py) on macOS, Windows, and Ubuntu every 24 hours and on every commit.

@slience-ops DNN inference is very simple:

python export.py --weights yolvo5s.pt --include onnx
python detect.py --weights yolvo5s.onnx --dnn

See Export tutorial for details:

Try to change that name to "images" in c++ code, or change the input node name to "onnx" when exporting in here (Some additional name changes are probably needed but I can't remember):

yolov5/export.py

Line 129 in 526e650

input_names=['images'],

I'm not 100% sure if this is the problem. I encounted a very similar problem in tensorrt deployment and fixed it this way.

@Zephyr69 thanks for sharing your solution! We appreciate your contribution to the YOLOv5 community. 🙌
To address the issue in C++, you can change the input node name to "images" directly in your C++ code. If you encounter any other issues, feel free to reach out for further assistance. Good luck with your project!
