Error: Can not use tune model because of some bugs

[HappyDoo]

Greetings everyone, my current endeavor involves fine-tuning the model. However, I've encountered an error of mysterious origins. Regrettably, I am facing challenges in rectifying this issue. If any of you could extend your assistance, I would greatly appreciate it.

Hi @HappyDoo, 

Thank you for reaching out to the community.

There are a number of reasons why you are having a failed DAG error message

• The tuning-graph task is used to tune hyperparameters of a machine, it is possible that the chosen hyperparameter are not optimal for your model hence the failed task error message
• The dataset used to train your model might not be enough, you can try increasing the size of your dataset
• A code error is also a probable cause, Kindly check on your codes to see if there are errors related to the failing task

You can refer to this troubleshooting guide and always check your cloud logs to see if there are tuning-graph related errors

Here are some resources that you may find useful:

• Overview of hyperparameter tuning
• Vertex AI Support

Hope this helps.
