In your case you make a small mistake that you put the single quote inside the function when function require an integer value.
在您的情况下，您犯了一个小错误，即当函数需要整数值时将单引号放在函数内。
echo get_the_post_thumbnail('637');
Bellow code are valid try it.
波纹管代码是有效的试试吧。
Simple Form
简单的形式
echo get_the_post_thumbnail(637);
Size Specified Form where second argument is the size of the image.
Size Specified Form 其中第二个参数是图像的大小。
echo get_the_post_thumbnail(637, array(100,100));
also you can try bellow code also
你也可以试试下面的代码
get_the_post_thumbnail(637); // without parameter -> Thumbnail get_the_post_thumbnail(637, 'thumbnail'); // Thumbnail get_the_post_thumbnail(637, 'medium'); // Medium resolution get_the_post_thumbnail(637, 'large'); // Large resolution get_the_post_thumbnail(637, 'full'); // Original resolution
Also you can refer to the WordPress codex Here. I am also going to write a full post on this topic on my blog

get_the_post_thumbnail($post_id, 'thumbnail'); // Thumbnail
get_the_post_thumbnail($post_id, 'medium'); // Medium resolution
get_the_post_thumbnail($post_id, 'large'); // Large resolution
get_the_post_thumbnail($post_id, 'full'); // Original resolution

Vallabh's solution works. This is how I use it as a background image:
Vallabh 的解决方案有效。这就是我将它用作背景图像的方式：
<?php if (has_post_thumbnail( $post->ID ) ) {
$image = wp_get_attachment_image_src( get_post_thumbnail_id(637), 'thumbnail' );
$image = $image[0];
} ?>
<div style="background-image: url(<?php echo $image; ?>)"> ... </div>

Create a post template..look like this(post_temp.php)
创建一个帖子模板..看起来像这样（post_temp.php）
<?php
$args=array('order'=> 'DESC', 'posts_per_page'=>get_option('posts_per_page'));
$query=new WP_Query($args);
if( $query->have_posts()):
while( $query->have_posts()): $query->the_post();
{
echo get_the_post_thumbnail($post->ID);
}
endwhile;
else:
endif;
?>
