iDetection models

Search before asking

• I have searched the YOLOv5 issues and discussions and found no similar questions.

Question

How did you convert the models for iDetection? Did you use coreml or torchscript? And if you used CoreML, please share the method with us. Because original script doesn't export Detection head. Screenshot from Netron.

Additional

This repo suggests to use torchscript model:

Requirements

Python>=3.6.0 with all requirements.txt installed including PyTorch>=1.7. To get started:

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

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.

@Vadbeg your code may be out of date, all export formats contain all model modules including Detect.

[Vadbeg]

@glenn-jocher Okay, please, try the command below and send the screenshot of the resulting model to Neutron.

python export.py --include coreml --img 640

Because with the latest version of code, when I run script for detection:

python detect.py --weights ../weights/best.mlmodel --source ../data/images/test --img-size 640 --hide-labels --hide-conf

I get this error:

I am seeing the same issue using the latest version.

[glenn-jocher]

@Vadbeg @congxing good news 😃! Your original issue may now be fixed ✅ in PR #6195. This PR adds support for YOLOv5 CoreML inference.

!python export.py --weights yolov5s.pt --include coreml  # CoreML export
!python detect.py --weights yolov5s.mlmodel  # CoreML inference (MacOS-only)
!python val.py --weights yolov5s.mlmodel  # CoreML validation (MacOS-only)

model = torch.hub.load('ultralytics/yolov5', 'custom', 'yolov5s.mlmodel')  # CoreML PyTorch Hub model

To receive this update:

• Git – git pull from within your yolov5/ directory or git clone /~https://github.com/ultralytics/yolov5 again
• PyTorch Hub – Force-reload model = torch.hub.load('ultralytics/yolov5', 'yolov5s', force_reload=True)
• Notebooks – View updated notebooks
• Docker – sudo docker pull ultralytics/yolov5:latest to update your image

Thank you for spotting this issue and informing us of the problem. Please let us know if this update resolves the issue for you, and feel free to inform us of any other issues you discover or feature requests that come to mind. Happy trainings with YOLOv5 🚀!

Thanks for fixing @glenn-jocher. I verified it was working on yolov5.mlmodel. However, for a customized model which is trained on another dataset, it seems the exported coreml model showing old labels using detect.py.

For example, I trained the model on a custom dataset with two labels ['pet', 'person']. Using best.pt, the detected box is marked as 'person', but best.mlmodel shows bicycle instead.

[glenn-jocher]

@congxing ah yes, thanks for the feedback! The CoreML models do not contain class names embedded, these are sourced from the data.yaml, which defaults to COCO128. I'll think about how to handle this better:

yolov5/detect.py

Line 220 in 00d7b97

parser.add_argument('--data', type=str, default=ROOT / 'data/coco128.yaml', help='(optional) dataset.yaml path')

[congxing]

Got it. Thanks for the pointer.
