标签： ionic-framework responsive-design ionic2

我有一张卡片列表，我需要在小型设备的1列中显示它们，在中型设备中显示2列，在大型设备中显示3列

基于https://stackoverflow.com/a/36432126/2279488和https://stackoverflow.com/a/36432126/2279488我尝试了下面的代码，但最后没有成功。

1 

 <ion-row  responsive-sm>
    <ion-col *ngFor="let card of cards" width-50>
      <ion-card >

在小型设备上显示正确，在大型和中型上它只显示2张卡

2 

  <ion-row  responsive-sm>
    <ion-col  width-50>
      <ion-card *ngFor="let card of cards">

在小型设备上显示正确，大型和中型1列显示，所有卡都在列

3 

  <ion-row  responsive-sm>
    <ion-col>
      <ion-card *ngFor="let card of cards">

在小型设备上显示正确，在中型和大型上它只显示1列，卡显示在该列中

我找到了解决方案，以防其他人遇到同样问题

我在第一段代码中添加了包装，但它确实有效。

 File "holt.py", line 7, in <module>
from tensorflow import tf


File "/usr/local/lib/python2.7/dist-packages/tensorflow/__init__.py", line 24, in <module>
from tensorflow.python import *


 File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/__init__.py", line 91, in <module>
from tensorflow.python.summary import summary


 File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/summary/summary.py", line 41, in <module>
from google.protobuf import json_format as _json_format
ImportError: cannot import name json_format

我在我的HTML下面添加了代码，它为我工作。
