AttributeError: 'InstanceData' object has no attribute 'masks'

AttributeError: 'InstanceData' object has no attribute 'masks'这个错误通常是因为在InstanceData对象中找不到名为'masks'的属性。可能原因是代码中没有正确地定义或初始化该属性，或者在使用该属性之前没有对其进行赋值。要解决这个问题，你可以检查代码中是否正确定义了InstanceData类，并确保在使用'masks'属性之前对其进行了赋值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
