ModuleNotFoundError: No module named 'u8darts'

Question

I am trying to use darts library to forecast price using transformer neural nets. through ubuntu20.4 terminal and python 3.10.

The below is my code, where I just calling and Importing necessary libraries:

from os.path import dirname, basename
from os import getcwd
import sys


def fix_pythonpath_if_working_locally():
     """Add the parent path to pythonpath if current working dir is darts/examples"""
     cwd = getcwd()
     if basename(cwd) == 'examples':
        sys.path.insert(0, dirname(cwd))

fix_pythonpath_if_working_locally()

warnings.filterwarnings("ignore")

But I have got this error:

How can I fix this error?(I have use pip install u8darts in terminal and installed successfully)
