Unable to access/download datasets

Hello, I am a newbie to HF platform, so pardon my ignorance if the question is too basic, I am unable to load most datasets, I have tried downloading multiple datasets, but haven’t have any luck except for maybe one (lysandre/arxiv-nlp)

e.g of datasets that I cannot list or download
m-a-p/Matrix
xingyaoww/code-act
Zyphra/Zyda
and many more, but everytime, I get the same error,

e.g. when reading xingyaoww/code-act dataset

Traceback (most recent call last):
File “/usr/local/lib/python3.11/site-packages/huggingface_hub/utils/_errors.py”, line 286, in hf_raise_for_status

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://huggingface.co/api/models/xingyaoww/code-act/tree/main?recursive=False&expand=False

The above exception was the direct cause of the following exception:

I have created the token and am passing the token along with the request but I still cannot get over the error, maybe I am missing something, can someone please help, thanks
