NameError: name 'ImageClassifierDataLoader' is not defined

In Chapter9_ModelMaker.ipynb, I encounter the following error messages (pardon the long list):

# neccessary packages
import numpy as np
import tensorflow as tf
assert tf.__version__.startswith('2')
from tflite_model_maker import configs
from tflite_model_maker import ExportFormat
from tflite_model_maker import image_classifier
from tflite_model_maker import ImageClassifierDataLoader
from tflite_model_maker import model_spec

ModuleNotFoundError: No module named 'tensorflowjs'

... your existing code runs fine here, omitted for brevity

# review directory listing
os.listdir(image_path)
['tulips', 'daisy', 'roses', 'LICENSE.txt', 'dandelion', 'sunflowers']

# prepare dataset
data = ImageClassifierDataLoader.from_folder(image_path)
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)

      1 # prepare dataset
----> 2 data = ImageClassifierDataLoader.from_folder(image_path)

NameError: name 'ImageClassifierDataLoader' is not defined

Since I do not have a need for tensorflowjs in Chapter 9, what is the workaround to suppress this message? Thanks.

Regards.
