If you receive an HTTP 429 Rate limit exceeded error when calling wandb.log(), you are exceeding the rate limit quota for your project. W&B applies rate limits per project, and paid plans have higher limits than free plans.

​
How to stay under the rate limit

  1. Update your W&B SDK: The latest version includes optimized mechanisms for retrying requests and managing quota usage. 
    pip install --upgrade wandb
  2. Reduce logging frequency: Log metrics less often. For example, log every N epochs instead of every epoch: 
    for epoch in range(100):
    if epoch % 5 == 0:
        wandb.log({"acc": accuracy, "loss": loss})
  3. Sync data manually: If you are rate limited, W&B stores your run data locally. You can sync it later with: 
    wandb sync <run-file-path>

​
Rate limit headers

When rate limited, the response includes these headers:
HeaderDescription
RateLimit-RemainingQuota remaining in the current window (0–1000 scale)
RateLimit-ResetSeconds until the current quota resets
If RateLimit-Remaining is 0, wait for the number of seconds in RateLimit-Reset before retrying. For more information, see Experiments limits and performance.
