Hello,

I have tried generating certificate of completion for the aforementioned course. I entered username, first and last name and see an error. I attach a screenshot of the result I get. I couldn’t find any guidance online. How can I get it to work?

Thanks in advance

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](https://huggingface.co/spaces/huggingface-projects/Deep-RL-Course-Certification/discussions/17)  
I also added notes to the existing GitHub issue: [[UPDATE] Deep-RL-Course-Certification is broken · Issue #604 · huggingface/deep-rl-class · GitHub](https://github.com/huggingface/deep-rl-class/issues/604#issuecomment-4839523647)

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