1. Users are experiencing model loading failures due to corrupted downloads
2. The error message indicates that tensor data is not within file bounds
3. Currently, there's no built-in validation to catch this issue after download
4. The workaround is to manually remove and re-download the model

Proposed Solution:

Short-term:

• Provide clear instructions to users on how to remove and reinstall corrupted models
• Consider adding this process to the app's troubleshooting guide

Long-term:

• Implement post-download file validation to detect corrupted or incomplete model files
• Add error handling to gracefully manage and report download issues
• Consider implementing resume functionality for interrupted downloads to prevent corruption
