Hi [deleted user], have you imported the dataset to your local machine using dvc get? As in:
$ dvc get https://github.com/iterative/aita_dataset aita_clean.csv
I can’t tell if you’ve done this step yet. If you didn’t, then the file won’t be in your local workspace and pandas won’t be able to import it. After doing dvc get, you should be able to open Python and run
df = pd.read_csv("aita_clean.csv")
