I had gotten the same message. When I add the following, it works:

!pip install darts

from darts import TimeSeries

import warnings

warnings.filterwarnings("ignore")
import logging

logging.disable(logging.CRITICAL)

from darts.

Found the issue. This module doesnt work for python < 6.5.10

from darts.

Hi @lucasaos52, thank you for reporting the issue and glad that you managed to find a solution that works for you.

from darts.

Hi @lucasaos52, could you pls clarify which version of python is not supported?
I am in doubt of the version you mentioned (6.5.10), because python version goes up to 3.9. Tks.

from darts.

Same issue i am facing

from darts.

@rishikeshkushwaha can you confirm that you installed the package?
What do you obtain when typing pip freeze |grep darts ?
