Weights & Biases (wandb) is a powerful tool designed for machine learning practitioners to track experiments, visualize results, and collaborate with team members. It provides a comprehensive suite of features that help in managing machine learning workflows, including experiment tracking, hyperparameter tuning, and model versioning. By integrating wandb into your projects, you can easily monitor the performance of your models and share insights with your team.
While using wandb, you might encounter the error message: wandb: ERROR Invalid run name. This error typically appears when you attempt to initiate a new run with a name that does not comply with wandb's naming conventions.
When this error occurs, the run fails to start, and you receive an error message indicating that the run name is invalid. This can be frustrating, especially when you are in the middle of an important experiment.
The Invalid run name error is triggered when the run name contains characters that are not allowed or when the name exceeds the maximum length permitted by wandb. Run names in wandb should be alphanumeric and adhere to specific length constraints to ensure compatibility and readability across different platforms and interfaces.
To resolve this issue, you need to ensure that your run names are compliant with wandb's naming rules. Follow these steps to fix the error:
Review the run name you are using and ensure it only contains alphanumeric characters. Avoid using special characters such as !@#$%^&*() or spaces.
Ensure that the run name does not exceed the character limit set by wandb. Typically, keeping the name under 64 characters is a safe practice.
If the run name contains invalid characters or is too long, modify it accordingly. For example, instead of using "Experiment #1: Test Run", use "Experiment1_TestRun".
After making the necessary changes, restart the run with the corrected name. This should resolve the error, and your experiment should proceed without issues.
For more information on wandb's naming conventions and best practices, you can refer to the official wandb documentation. Additionally, if you encounter further issues, consider reaching out to the Weights & Biases community for support.
