I'm currently able to echo the image and it's working perfectly.

Here's the code I'm using:
这是我正在使用的代码：
<?php

<?php /* The loop */ ?>
? ?<?php while ( have_posts() ) : the_post(); ?>
? ?<div class="header-image">

Here's a solution:
这是一个解决方案：
$thumbnail_id = get_post_thumbnail_id($post->ID);
$thumbnail_image = get_posts(array('p' => $thumbnail_id, 'post_type' => 'attachment'));
if ($thumbnail_image && isset($thumbnail_image[0])) {
echo '<span>'.$thumbnail_image[0]->post_excerpt.'</span>';
}
Or you can use your code, but instead of echoing $altdirectly you need to echo $alt->post_excerpt.
或者您可以使用您的代码，但不是$alt直接回显，而是需要 echo $alt->post_excerpt。

Check if you get correct thumbnail id.
For me this code works perfect:
检查您是否获得正确的缩略图 ID。
对我来说，这段代码很完美：
$thumbnail_id = get_post_thumbnail_id( $post->ID );
$alt = get_post_meta($thumbnail_id, '_wp_attachment_image_alt', true);
