cannot load the model in Azure ML - azure

Question

when I try to load a model in Azure ML with below code I get an error.
anyone know how to fix the issue with Azure?
from tensorflow import keras
keras.models.load_model('model.h5')
AttributeError Traceback (most recent call last)

When we are calling the model we first need to consider tensorflow library and before that OS library.
import os
import tensorflow as tf
from tensorflow import keras
In the given question, tensorflow was not called and even if it was imported, to load the H5 model, we need to use tensorflow. Replace the existing code block of loading with the below code block.
import os
import tensorflow as tf
from tensorflow import keras
tf.keras.models.load_model(filepath, custom_objects=None, compile=True)
this is the procedure to call the model to solve the current issue.
