Get learning rate of keras model

Question

I cannot seem to get the value of learning rate. What I get is below.

I've tried the model for 200 epochs and want to see/change the learning rate. Is this not the correct way?

>>> print(ig_cnn_model.optimizer.lr)
<tf.Variable 'lr_6:0' shape=() dtype=float32_ref>

Answer 1

Use eval() from keras.backend:

import keras.backend as K
from keras.models import Sequential
from keras.layers import Dense

model = Sequential()
model.add(Dense(1, input_shape=(1,)))
model.add(Dense(1))
model.compile(loss='mse', optimizer='adam')

print(K.eval(model.optimizer.lr))

Output:

0.001
