Nova Pro finetune job keeps stuck

Based on your description, your Nova Pro fine-tuning job has been stuck in "Not Started" status for an extended period (14 hours), which is unusual.

There are a few ways to troubleshoot this issue:

1. Check if you've hit any service quotas or limits for Bedrock model customization jobs. Even if you're not running multiple jobs concurrently, there might be account-level quotas affecting your job.

2. Verify that your input data in S3 is correctly formatted and accessible. Make sure the S3 bucket permissions are properly configured to allow Bedrock to access your training data.

3. Review the IAM role you provided for the fine-tuning job. The role needs appropriate permissions to access your S3 buckets (both input and output) and to perform model customization operations.

4. Look for any error messages or logs in CloudWatch that might provide more insight into why the job isn't starting.

5. If you created the job using the API, double-check that all required parameters were correctly specified, including hyperparameters like stepCount, batchSize, and learningRate.

If none of these steps help identify the issue, I'd recommend contacting AWS Support for further assistance. They can look into the specifics of your account and job configuration to identify any underlying issues that might be preventing the job from starting.
