Common Issues with Weights & Biases

See detailed troubleshooting guides for the most common Weights & Biases errors:

API Error (500 / 502 / 503)

Weights & Biases is returning API errors (HTTP 500, 502, or 503), indicating the platform's backend is experiencing issues. MLOps platforms handle complex workloads — model training, experiment tracking, pipeline orchestration — making server errors particularly disruptive to active workflows.

Pipeline / Training Run Failed

Your ML pipeline or training run on Weights & Biases has failed unexpectedly. This can be caused by platform-side issues (compute unavailability, orchestration bugs) or configuration problems on your end. Distinguishing between the two is key to a fast resolution.

Model Registry / Artifact Store Error

You cannot push, pull, or access model artifacts in Weights & Biases's model registry. This blocks model deployment and versioning workflows. Registry errors are often caused by storage backend issues or permission problems.
