Question

目前，我这样做：

<div class="everything">
  <br style="line-height:15px;">
  <section class="info-boxes">
    <ul class="infobox-list">
      
      
      <li>
        <a href="javascript:void(0);">
          <div class="infobox">
            <table>
              <tr>
                <img class="profile" src="http://res.cloudinary.com/djxai1v1e/image/upload/v1497467825/Profile-Icon_oy7oxz.png"></tr>
              <tr>
                <p class="ptext">My Profile</p>
              </tr>
            </table>
            <div class="open"></div>
          </div>
          <div class="shade">

我想做这样的事情：

import tensorflow as tf
keras = tf.contrib.keras
Sequential = keras.models.Sequential
Dense = keras.layers.Dense
Dropout = keras.layers.Dropout
Flatten = keras.layers.Flatten
Conv2D = keras.layers.Conv2D
MaxPooling2D = keras.layers.MaxPooling2D

但是当我尝试这个时，我得到了

import tensorflow as tf
keras = tf.contrib.keras
from tf.contrib.keras import (Sequential, Dense, Dropout, Flatten,
                              Conv2D, MaxPooling2D)

是否有比第一个代码块更短的方式来导入这些类？

其他尝试

ImportError: No module named tf.contrib.keras

Nr 2

>>> from tensorflow.contrib.keras import (Sequential, Dense, Dropout, Flatten)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name Sequential

Answer 1

首先，您需要使用tensorflow模块的实际名称导入，而不是您用于它的tf别名：

其次，tensorflow.contrib.keras的包结构有点奇怪。名字

tensorflow.contrib.keras.models
tensorflow.contrib.keras.layers

实际上是更深层嵌套模块的别名

tensorflow.contrib.keras.api.keras.models
tensorflow.contrib.keras.api.keras.layers

以及创建这些别名的方式不允许您使用from导入来导入其内容。您可以直接使用“真实”名称：

from tensorflow.contrib.keras.api.keras.models import Sequential
from tensorflow.contrib.keras.api.keras.layers import (
        Dense, Dropout, Flatten, Conv2D, MaxPooling2D)

（这里有更多的别名 - tensorflow.contrib.keras.api.keras.*模块从tensorflow.contrib.keras.python.keras中提取大部分内容 - 但我们无需担心这一点。）

Answer 2

试试这个：

from tensorflow.contrib.keras.models import Sequential
from tensorflow.contrib.keras.layers import Dense, Dropout, Flatten, Conv2D, MaxPooling2D

是否有更短的方法来导入子模块的类？
