I am new to Tensorflow and trying to work on it using the sample code below:



def build_model():
model = keras.Sequential([
layers.Dense(10, activation=tf.nn.relu),
layers.Dense(10, activation=tf.nn.relu),
layers.Dense(1)
])
optimizer = tf.keras.optimizers.RMSprop(0.001)

model.compile(loss='mean_squared_error',
optimizer=optimizer,
metrics=['mean_absolute_error', 'mean_squared_error'])
return model

model = build_model()
model.fit(training_dataset, epochs=5, steps_per_epoch=179)


The training_dataset is as below with 179 rows:

Can anyone advise on how to fix it?
