Hi,
While running the following cell of notebook 05, I am getting the below error.
Please note that also tried with the notebooks from the the course repo but it's throwing the same error.
`
Code
1. Create base model with tf.keras.applications
base_model = tf.keras.applications.EfficientNetB0(include_top=False)
2. Freeze the base model (so the pre-learned patterns remain)
base_model.trainable = False
3. Create inputs into the base model
inputs = tf.keras.layers.Input(shape=(224, 224, 3), name="input_layer")
4. If using ResNet50V2, add this to speed up convergence, remove for EfficientNet
#x = tf.keras.layers.experimental.preprocessing.Rescaling(1./255)(inputs)
5. Pass the inputs to the base_model (note: using tf.keras.applications, EfficientNet inputs don't have to be normalized)
x = base_model(inputs)
#Check data shape after passing it to base_model
print(f"Shape after base_model: {x.shape}")
6. Average pool the outputs of the base model (aggregate all the most important information, reduce number of computations)
x = tf.keras.layers.GlobalAveragePooling2D(name="global_average_pooling_layer")(x)
print(f"After GlobalAveragePooling2D(): {x.shape}")
7. Create the output activation layer
outputs = tf.keras.layers.Dense(10, activation="softmax", name="output_layer")(x)
8. Combine the inputs with the outputs into a model
model_0 = tf.keras.Model(inputs, outputs)
9. Compile the model
model_0.compile(loss='categorical_crossentropy',
optimizer=tf.keras.optimizers.Adam(),
metrics=["accuracy"])
10. Fit the model (we use less steps for validation so it's faster)
history_10_percent = model_0.fit(train_data_10_percent,
epochs=5,
steps_per_epoch=len(train_data_10_percent),
validation_data=test_data_10_percent,
#Go through less of the validation data so epochs are faster (we want faster experiments!)
validation_steps=int(0.25 * len(test_data_10_percent)),
#Track our model's training logs for visualization later
callbacks=[create_tensorboard_callback("transfer_learning", "10_percent_feature_extract")])`
