Bug: W&B API Key length validation error (40-character limit)

[georginapetr]

Dear YAIB team,

I am attempting to reproduce the YAIB benchmarks but I am encountering a strict character validation error when setting up Weights & Biases.

The Issue:
When running the following command:
wandb sweep --verbose experiments/benchmark_classification.yml

The system prompts for a W&B API key but rejects any input that is not exactly 40 characters long. Modern W&B API keys (formatted as wandb_v1_...) are significantly longer than this legacy limit.

Troubleshooting already attempted:

• Exporting the key directly via environment variables (export WANDB_API_KEY=...).

• Manually editing configuration files/.netrc.

• The system continues to enforce the length constraint regardless of the input method.

Environment:

• OS: macOS Big Sur, version 11.7.10 (20G1427)

• W&B Version: version 0.18.7

YAIB Branch: development (as seen in my local setup)

Expected Behavior:
The system should accept modern, variable-length W&B API keys.

Thank you for your help!

All the best,
Georgina Petropoulou

hi @georginapetr ,

Thanks for the issue!

Could you try manually updating W&B using pip and see if that resolves the problem? I am not sure when this changed.
I.e.,:
pip install <package-name>==<version>
