Bootstrap carousel Images not showing

I am using carousel with lazy loading ,so that images load only on scroll, But problem is that all images except images inside carousel are not loading. I have also tried this solution.

Carousel

     <div class="owl-carousel">

         </div>
     </div>

Script

    <script>
$('.owl-carousel').owlCarousel({
    loop:true,
    margin:10,
    responsiveClass:true,
    autoplay:true,
    autoplayTimeout:2000,
    rewindSpeed : 1000,
    responsive:{
        0:{
            items:1,
            nav:true
        },
        600:{
            items:2,
            nav:false
        },
        1000:{
            items:3,
            nav:true,
        }
    }
})
</script>

Lazy Loading

  <script>
$(function() {


    
    $('.lazy').lazy({
        beforeLoad: function(element){
            console.log('image "' +element.data('src')+ '" is about to be loaded');
        },
        afterLoad: function(element) {
           
            console.log('image "' +element.data('src') + '" was loaded successfully');
        },
        onError: function(element) {
            console.log('error');
        },
        onFinishedAll: function() {
       
            console.log('lazy instance is about to be destroyed')
        }
    });


});
</script>

Please help what i am doing wrong,I have also tried changing order of script but no luck.

Add this to owl item

    .owl-item {
    display: inline-block;
     }

One more Issue : I assume that the content outside the div should be hidden

    .owl-carousel{
    overflow:hidden;
     }
