每当我尝试将滑块添加到推荐部分时，滑块都没有实现。行明智的推荐正在显示。我试过代码是正确的，但不知道为什么滑块没有实现。
我的代码是：
<div class="heading white-heading">
Testimonial
</div>
<div id="testimonial4" class="carousel slide testimonial4_indicators testimonial4_control_button thumb_scroll_x swipe_x" data-ride="carousel" data-pause="hover" data-interval="5000" data-duration="2000">
<div class="carousel-inner" role="listbox">
<div class="carousel-item active">
<div class="testimonial4_slide">
<img src="https://i.ibb.co/8x9xK4H/team.jpg" class="img-circle img-responsive" />
