Error Generating Deep RL Course Certificate

A user reported an error generating a certificate for the Deep RL Course on Hugging Face. Investigation revealed the app computes a passing score of 81.8% but fails at writing to the official certified_users.csv dataset, likely due to token or permission issues. The problem requires a maintainer to check the Space logs and dataset write permissions.

Hi.

I am not a maintainer, but I investigated this in a duplicated version of the Certification Space.

Using your username, the app was able to find your models, parse the model-card metadata, and compute a pass percentage of about 81.8%, which should qualify for the completion certificate. So this does not look like a simple “below 80%” or “models not found” case. In my duplicate, the remaining failure happened at the final writeback step, where the Space tries to update certified_users.csv

in the official huggingface-projects/Deep-RL-Course-Certification dataset. My token cannot write to that official dataset, so I cannot fully reproduce the official environment. However, when I bypassed that writeback step, the certificate image and progress table rendered normally.

I opened a Hub PR with the details: huggingface-projects/Deep-RL-Course-Certification · Improve Deep RL certification Space runtime pins and writeback errors

I also added notes to the existing GitHub issue: [UPDATE] Deep-RL-Course-Certification is broken · Issue #604 · huggingface/deep-rl-class · GitHub

This likely needs a maintainer to check the official Space logs, HF_TOKEN secret, and dataset write permissions.
