from tensorflow.contrib.layers import l2_regularizer, xavier_initializer ModuleNotFoundError: No module named 'tensorflow.contrib'

问题:from tensorflow.contrib.layers import l2_regularizer, xavier_initializer ModuleNotFoundError: No module named 'tensorflow.contrib'

回答: 这个问题是因为在TensorFlow 2.0中，tensorflow.contrib模块被移除了。所以无法直接使用from tensorflow.contrib.layers导入l2_regularizer和xavier_initializer。在最新的TensorFlow版本中，你可以使用tf.keras模块中的相应函数来替代。例如，你可以使用tf.keras.regularizers.l2来替代l2_regularizer，使用tf.keras.initializers.glorot_uniform或tf.keras.initializers.glorot_normal来替代xavier_initializer。所以你可以将代码中的import语句修改为以下形式:

from tensorflow.keras.regularizers import l2
from tensorflow.keras.initializers import GlorotUniform, GlorotNormal

然后在代码中使用l2()替代l2_regularizer()，使用GlorotUniform()或GlorotNormal()替代xavier_initializer_conv2d()。

这样修改后，你的代码将不再依赖于tensorflow.contrib模块，而是使用了TensorFlow 2.0中的tf.keras模块中的函数。<em>1</em><em>2</em><em>3</em>
