“Could not interpret optimizer identifier” error in Keras

Question

I got this error when I tried to modify the learning rate parameter of SGD optimizer in Keras. Did I miss something in my codes or my Keras was not installed properly?

Answer 1

I tried the following and it worked for me:

from keras import optimizers

sgd = optimizers.SGD(lr=0.01)

model.compile(loss='mean_squared_error', optimizer=sgd)
