Wechat applet swiper simple local picture display appears large blank

Question picture
This large blank slide
My code ：

<view>
    <swiper class="swiper-view"
            indicator-dots="true"autoplay="true" 
            interval="2000"  circular="true"
            indicator-color="#ccc" indicator-active-color="#fff">
      <swiper-item class="swiper-image">
        <image src="/images/1.jpg"></image>
      </swiper-item>
      <swiper-item class="swiper-image">
        <image src="/images/2.jpg"></image>
      </swiper-item>
      <swiper-item class="swiper-image">
          <image src="/images/3.jpg"></image>
      </swiper-item>
    </swiper>
  </view>

There seems to be no problem , Thought there was a problem with the settings
Look at the official documents
swiper| Wechat development documents
ok, Every sentence has no problem . So check it out WXML

Delete view Perfect solution or give view Add class

Query parent element
