On my linux python 3.7 virtual environment, I have installed the latest pycaret from pip, I get the error below while importing?

I am following the example on the notebook below;
https://nbviewer.org/github/pycaret/pycaret/blob/time_series_beta/time_series_101.ipynb

import time
import numpy as np
import pandas as pd

from pycaret.datasets import get_data
from pycaret.internal.pycaret_experiment import TimeSeriesExperiment
