@chang-1 hello! It looks like you're encountering a JSON decoding error with the Objects365 validation labels. This error typically indicates an issue with the JSON file itself, such as it being incomplete or corrupted. Here are a few steps you can take to resolve this issue:

1. Verify the JSON File: Ensure that the zhiyuan_objv2_val.json file has been fully downloaded without any interruptions. Sometimes, network issues can result in incomplete downloads.

2. Check for Corruption: Open the JSON file in a text editor and check for any obvious signs of corruption, especially near the end of the file. The error message points to an unterminated string, which could mean the file was cut off.

3. Re-download the File: If possible, try re-downloading the validation labels file from the original source to ensure you have a complete and uncorrupted version.

4. JSON Validation: Use a JSON validator tool to check for any syntax errors in the file. This can help identify the exact location of the issue within the JSON structure.

If after these steps you're still facing issues, it might be helpful to look into any specific requirements or known issues with the Objects365 dataset and YOLOv5 compatibility. For further assistance, you can refer to our documentation at https://docs.ultralytics.com/yolov5/ which might provide additional insights or steps for troubleshooting dataset issues.
