why showing error here? I was trying to implement VGG16 model but there have an error...!!

model.compile(loss='categorical_crossentropy', optimizer=optimizers.Nadam(lr=2e-5), metrics=['acc'])

CodePudding user response：

keras.optimizers.Adam
https://keras.io/api/optimizers/adam/
It's a misspelled word

CodePudding user response：

Depending on which version of keras and tensorflow you are using, you can import Nadams in either way (keras is now part of tensorflow):

from tensorflow.keras.optimizers import Nadam

OR

from keras.optimizers import Nadam

and then use it as:

Nadam(learning_rate=0.0001)

Sample usage:

from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Dense
from tensorflow.keras.optimizers import Nadam

model = Sequential()
model.add(Dense(10, input_dim=20, activation='relu'))
model.add(Dense(1, activation='sigmoid'))
model.compile(optimizer=Nadam(learning_rate=0.0001), loss='binary_crossentropy', metrics=['accuracy'])
model.summary()
