[UltralyticsAssistant]

👋 Hello @sj746, thank you for your interest in YOLOv5 🚀!

It seems like you are encountering a certificate verification issue. If this is a 🐛 Bug Report, could you please provide a minimum reproducible example (MRE)? This would greatly help us diagnose the issue. Be sure to include all relevant details such as scripts, configurations, and any necessary context.

If you're asking a ❓ Question, please share any additional information that could help us assist you better. For instance, the Python version, operating system details, and how you installed dependencies would be valuable.

Requirements

Ensure your Python version is 3.8.0 or newer and all required dependencies are installed. Make sure PyTorch version is 1.8 or above as well.

Environments

YOLOv5 supports many tested environments such as Notebooks with GPU, cloud platforms, or Docker. Double-check that your environment meets the expected setup.

Status ⬆️

Lastly, you can check our continuous integration (CI) badge on the repository page to see if the latest tests have passed. Our CI tests regularly verify YOLOv5 operations on a variety of platforms.

😄 This is an automated reply to get you started. An Ultralytics engineer will review your question and assist you further soon!

@sj746 the error indicates an SSL certificate verification failure when attempting to download a font file. This is a common issue on macOS where the system's certificate store is not correctly configured for Python.

To resolve this, run the following command to install or update the certificates for Python:

/Applications/Python\ 3.10/Install\ Certificates.command

If you are using a virtual environment, ensure it inherits the certificates from the system installation. After running the command, retry the training script. Let me know if additional issues arise!

Thank you for the details. As mentioned earlier, the issue is due to SSL certificate verification failure on macOS. Please run /Applications/Python\ 3.10/Install\ Certificates.command to install or update your Python certificates. If you're using a virtual environment, ensure it inherits the updated certificates.
