That is because you do not have access to this repo, and this is the one used by default for the test. To be able to run the test on your side:

• Create a model repo on the Hub
• Set the environment variable CUSTOM_CACHE_REPO=the-name-of-your-model-repo
• Set the environment variable HF_TOKEN=your-hf-token-that-provides-access-to-the-repo
