[Python] Unrecognized keyword arguments passed to DepthwiseConv2D: {'groups': 1} error when...

I'm trying to load this face anit-spoofing model. It is a MobileNetV2 model. I want to convert it to coreML format. I have uploaded the .h5 model file into the colab. But when I try to load the model using tensorflow I get this following error.


ValueError: Unrecognized keyword arguments passed to DepthwiseConv2D: {'groups': 1}

During handling of the above exception, another exception occurred:


Here is my python code to load the model and print the model summary. The tensor flow version in Colab 2.17 I have downgraded it to 2.16 because I found this API documentation for DepthWiseConv2D for tensorflow version 2.16. But still the same error occurs. Here is my code

import tensorflow as tf
import coremltools as ct


model = tf.keras.models.load_model('/content/MobileNetV2.h5')
print(model.summary())


When I run the code it gives me this error
