@willuhmjs hello! 👋

Thank you for bringing this issue to our attention. It seems you're encountering a problem with data not uploading to the Ultralytics HUB when training with multiple GPUs. This is indeed unusual, and we appreciate your detailed report.

A few things to consider that might help resolve this issue:

1. Check Network Connectivity: Ensure that your High-Performance Computing (HPC) environment has stable internet access throughout the training process. Network instability could cause the upload process to fail.

2. Verify HUB Version: Make sure you're using the latest version of the Ultralytics HUB. Outdated versions might have compatibility issues or bugs that have been addressed in newer releases.

3. Review HPC Restrictions: Some HPC environments have strict firewall rules or network policies that might restrict data uploads. It's worth checking with your system administrator if there are any such limitations in place.

4. Single GPU Test: As a diagnostic step, try running a smaller training job with a single GPU to see if the issue persists. This can help isolate whether the problem is specifically related to multi-GPU setups.

5. Logs and Error Messages: If possible, review any logs or error messages generated during the training process. These can provide valuable clues about what might be going wrong.

For further troubleshooting and guidance, please refer to our documentation at https://docs.ultralytics.com/hub. If the issue persists, feel free to provide additional details such as logs or error messages, and we'll be happy to assist further.

Thanks for your contribution to the Ultralytics community! 🚀

@darkkun0824 hello again! 👋

It's insightful to know that the issue is specifically occurring in a multi-GPU setup, especially with high-end GPUs like the A100s, but works fine with a single GPU. This narrows down the scope of the problem significantly.

Given this additional context, here are a few more tailored suggestions:

1. Distributed Training Configuration: Ensure that your distributed training setup is correctly configured. Multi-GPU training often requires specific settings to manage data synchronization and communication effectively across GPUs.

2. Resource Monitoring: Monitor system resources during training. High-end GPUs like the A100 can process data very quickly, potentially leading to bottlenecks elsewhere in the system that might affect data upload processes.

3. Batch Size Adjustment: Consider adjusting your batch size. While larger batch sizes are feasible with more powerful GPUs, they might introduce unexpected behavior in how data is processed and uploaded.

4. Update Drivers and Libraries: Ensure that your NVIDIA drivers and CUDA libraries are up to date. Compatibility issues between drivers, CUDA, and PyTorch can lead to unexpected behavior in multi-GPU setups.

5. Consult HPC Documentation: Given the specialized nature of HPC environments, it's also a good idea to consult any available documentation or support resources specific to your HPC setup. There might be known issues or configurations specific to multi-GPU training in these environments.

If these steps do not resolve the issue, we recommend gathering detailed logs from your training sessions and reaching out for further support through our documentation portal at https://docs.ultralytics.com/hub. Detailed logs can provide crucial insights for deeper troubleshooting.

Thank you for your patience and for contributing to the Ultralytics community! We're here to help. 🌟
