I am trying to use an already trained model to transfer the learning to a model I will create and modifying only the last few layers. The goal of this is to used the already trained model (trained on millions of images already) to help my model classify food item recognition. I am pretty new to Keras and I am facing an issue that I am now starting understand to but don’t know how to resolve

# Load the model from TensorFlow Hub
model_url = "https://www.kaggle.com/models/tensorflow/resnet-50/TensorFlow2/classification/1"
hub_layer = hub.KerasLayer(model_url, input_shape=(224, 224, 3))

# Create a Sequential model
model = tf.keras.Sequential()

# Add the TensorFlow Hub layer to the Sequential model
model.add(hub_layer)

# Build the Sequential model
model.build((None, 224, 224, 3))

# Summary of the model
model.summary()

ERROR:
