Weights & Biases (wandb) is a powerful tool designed to help machine learning practitioners track and visualize their experiments. It provides a comprehensive suite of features for logging metrics, visualizing results, and managing model versions. By integrating wandb into your machine learning workflow, you can streamline the process of experimentation and collaboration, making it easier to reproduce results and share insights with your team.
One common issue users encounter when using wandb is the error message: wandb: ERROR Failed to resume run. This error typically appears when attempting to resume a previously paused or interrupted run. The symptom is straightforward: the run does not resume as expected, and the error message is logged in the console output.
The "Failed to resume run" error can occur for several reasons. The most common root cause is missing data or changes in the configuration since the run was paused. When a run is paused, wandb saves the state of the run, including the configuration and data. If any of these components are altered or lost, wandb may not be able to resume the run correctly.
To resolve this issue, follow these steps to ensure that your run can be resumed successfully:
Ensure that all data files and directories used in the original run are intact and accessible. If any files have been moved or deleted, restore them to their original locations. You can use commands like ls or dir to check the presence of necessary files:
ls /path/to/data
Review the configuration settings used in the original run. Ensure that no changes have been made to the configuration file or parameters. If changes are necessary, consider starting a new run instead of resuming the old one.
When resuming a run, use the appropriate wandb command. Ensure you specify the correct run ID. For example:
wandb agent //
Refer to the wandb documentation on resuming runs for more details.
Ensure that your network connection is stable. Network interruptions can cause issues with resuming runs. If you suspect network problems, try resuming the run from a different network or after resolving connectivity issues.
By following these steps, you should be able to diagnose and resolve the "wandb: ERROR Failed to resume run" issue. Ensuring data integrity and configuration consistency are key to successfully resuming your runs. For further assistance, consider reaching out to the Weights & Biases community or consulting the official documentation.
