TypeError: int() argument must be a string, a bytes-like object or a real number, not 'Timedelta'

[Rohith-Papani]

I got this issue while trying to load the data from NAB

code:
!pip install salesforce-merlion
!git clone https://github.com/salesforce/Merlion.git
!pip install Merlion/ts_datasets/

from ts_datasets.anomaly import NAB
import matplotlib.pyplot as plt
import numpy as np

np.random.seed(1234)
time_series, metadata = NAB(subset="realKnownCause")[1]

Can someone help me resolve this ?
