C2_W1_Assignment Exercise 1 "model undefined"

Hello.
I’m trying to do the first assignment, C2_W1_Assignment and I’m running into a problem. For the first exercise, I fill out the code cell, and then go to the next cell to execute model.summary(), and I get the following error:**
**
`NameError Traceback (most recent call last)
in
----> 1 model.summary()

NameError: name ‘model’ is not defined`

When I click on hints, the code is the same. When I run the code on my laptop, it runs as expected.

Your help is appreciated.

model = Sequential( [ tf.keras.Input(shape=(400,)), # specify input size

    ### START CODE HERE ###

    Dense(25, activation='sigmoid'),
    Dense(15, activation='sigmoid'),
    Dense(1, activation='sigmoid')

    ### END CODE HERE ###

], name="my_model"

)

After you edited the code cell, did you Run it?

Was this problem resolved? I’m seeing a similar problem; but different enough that I will open a new thread,
