I'm getting this error : 'AttributeError: module 'keras.optimizers' has no attribute 'Adam''

Question

我正在尝试运行在 Google Colab 中使用此代码：

从 keras 导入优化器来自 tensorflow.keras.optimizers 进口亚当

对于我在范围 (5) 中：

print(i)
model_mix = Model(inputs=[visible, visible1], outputs=x)
adam = optimizers.Adam(lr=0.01, beta_1=0.9, beta_2=0.999, epsilon=None, decay=0.0, amsgrad=False)
monitor = EarlyStopping(monitor='val_loss', min_delta=1e-3, patience=6, verbose=2, mode='auto') 
model_mix.compile(loss="mean_squared_error", optimizer=adam)
model_mix.fit(
    [x_text_train, x_img_train], y_text_train, callbacks=[checkpointer_cnn,monitor],**strong text**
    validation_data=([x_text_test, x_img_test], y_text_test),
    epochs=1000)

之前它运行良好，但现在它给我一个错误。有人可以帮我解决吗？

Answer 1

只需删除优化器，即 adam = Adam(lr=0.01, beta_1=0.9, beta_2=0.999, epsilon=None, decay=0.0, amsgrad=False) 它应该像这样工作。

Answer 2

可能是keras版本不同，在keras s2.8.0上试试：

 adam = optimizers.adam_v2.Adam(lr=0.01, ......)

Answer 3

使用这个

from tensorflow.keras.optimizers import Adam

而不是

from keras import optimizers from tensorflow.keras.optimizers import Adam

I'm getting this error : 'AttributeError: module 'keras.optimizers' has no attribute 'Adam''

I'm getting this error : 'AttributeError: module 'keras.optimizers' has no attribute 'Adam''
