Thank you for reporting this. I've tested this in a fresh Python 3.12 environment with u8darts==0.40.0, and the method works flawlessly on my side. Checking the 0.40.0 GitHub tag also confirms that to_dataframe is present in the TimeSeries class.

If you recently jumped from a version below 0.35.0 to 0.40.0, please ensure you have updated your code from the legacy .pd_dataframe() to the new .to_dataframe() method.

You can verify your installation with this snippet:

import pandas as pd
from darts import TimeSeries

series = TimeSeries.from_times_and_values(
    pd.date_range("2024-01-01", periods=3, freq="D"), [1, 2, 3]
)

try:
    print("Success:", series.to_dataframe().head(1))
except AttributeError:
    print("AttributeError: 'to_dataframe' not found.")

If you still encounter the error, please provide:

1. Clear instructions on your environment setup (OS, virtual environment manager, and full list of installed packages via pip freeze).
2. The specific code snippet you are using that triggers the error.

Please let us know if this resolves the issue!
