Conv2D keras中的稳压器

法纳兹

我看到人们在Dense层中使用了调节器，但是在keras文档中的Conv2d中有一个kernel_regulizer参数：

当我按如下方式添加稳压器时：

conv1 = Conv2D(32, (3, 15), strides=(1, 2), padding='same', data_format='channels_first', kernel_regularizer=regularizers.l2(), input_shape=x_train_n.shape[1:])(g0)

我收到此错误：

NameError: name 'regularizers' is not defined

我已经导入了：

import tensorflow as tf
from tensorflow.python.keras.models import Model
from tensorflow.python.keras.layers import Input, Activation, Conv2D, MaxPooling2D, BatchNormalization, UpSampling2D, Lambda, \
Conv2DTranspose, Permute, GaussianNoise, advanced_activations, Add, LeakyReLU, Dropout, ActivityRegularization
from tensorflow.python.keras import regularizers

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.figure as fgr
from tensorflow.python.keras import backend
from tensorflow.python.keras.utils import plot_model, normalize
from tensorflow.python.keras.callbacks import EarlyStopping

如何在Conv2D中调用稳压器？进口有冲突吗？

我能够运行您的代码而没有任何错误。我们唯一收到错误的是在@The Guy with The Hat提到的场景中，tensorflow.python.keras import regularizers在尝试制作Conv2D图层之前，未运行from的行。

在下面的代码中，注释了from tensorflow.python.keras import regularizers，然后我们得到了您提到的错误。

import tensorflow as tf
from tensorflow.python.keras.models import Model
from tensorflow.python.keras.layers import Input, Activation, Conv2D, MaxPooling2D, BatchNormalization, UpSampling2D, Lambda, \
Conv2DTranspose, Permute, GaussianNoise, advanced_activations, Add, LeakyReLU, Dropout, ActivityRegularization
# from tensorflow.python.keras import regularizers

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.figure as fgr
from tensorflow.python.keras import backend
from tensorflow.python.keras.callbacks import EarlyStopping

conv1 = Conv2D(32, (3, 15), strides=(1, 2), padding='same', data_format='channels_first', kernel_regularizer=regularizers.l2(), input_shape=(32,32,3))

输出-

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-1-2ab79df3a82b> in <module>()
     10 from tensorflow.python.keras.callbacks import EarlyStopping
     11 
---> 12 conv1 = Conv2D(32, (3, 15), strides=(1, 2), padding='same', data_format='channels_first', kernel_regularizer=regularizers.l2(), input_shape=(32,32,3))

NameError: name 'regularizers' is not defined

希望这能回答您的问题。学习愉快。
