keras.optimizers.Adam 在 Colab 中运行 GPU 代码时"not found module"错误

Question

我正在尝试运行代码导入keras。优化器亚当。我想从GPU做，因为我需要做一个长时间的训练。如果我正常运行，它可以工作，但每次我将运行时环境更改为GPU时，它都找不到模块"adam"。给出了下面的误差。由于与其他库的兼容性，我使用keras 2.2.4:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-12-ca97e5a6925a> in <module>()
8 from keras.models import Sequential
9 from keras.layers import Dense, Activation, Flatten, Convolution2D, Permute
---> 10 from keras.optimizers import Adam
11 import keras.backend as K
12 
ImportError: cannot import name 'Adam' from 'keras.optimizers' (/usr/local/lib/python3.7/dist-packages/keras/optimizers.py)

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

Answer 1

换行

from keras.optimizers import Adam

:

from tensorflow.keras.optimizers import Adam

，它会工作的。
