Pandas dataframe save to dataset gives error

I was looking for a way to write a logfile after my model has made a prediction but got stuck as the append mode is not supported by the file system
I tried to make a dataframe and save it - it is able to read and load the dataframe but unable to save it
I am following : Interact with the Hub through the Filesystem API

from huggingface_hub import HfFileSystem
import pandas as pd


fs = HfFileSystem(token=token)

df = pd.read_csv(“hf://datasets/sujitb/data/querylog.csv”)

till this it works fine


throws error

RepositoryNotFoundError: 401 Client Error. (Request ID: Root=1-66098a8a-2f8d371169e6f6991a126d89;3366d0ed-0e17-4061-8f41-845dfdc872a4)

Repository Not Found for url:

Note: Creating a commit assumes that the repo already exists on the Huggingface Hub. Please use create_repo if it’s not the case.

Has anyone faced this or got around this issue?

Hi ! you need to login using huggingface-cli login command or pass your token as storage_options (it’s just a dict containing your token)

fs = HfFileSystem(token=token)
df.to_csv(“hf://datasets/sujitb/data/querylog.csv”, storage_options=fs.storage_options)

Otherwise df.to_csv will use a brand new HfFileSystem() without token to upload the file and fail

Thanks a lot for your response ! Passing the storage_options solved my problem. I just passed a dict {“token”:‘xxxxxxxxxxx’} and it worked.
