AttributeError: 'list' object has no attribute 'is_Relational'

# 该错误是因为列表对象没有shape属性，通常shape属性是用于numpy数组的，如果要获取列表的长度，可以使用len()函数。
# 以下是解决方法：
list_example = [1, 2, 3, 4, 5]
print(len(list_example))  # 输出：5

AttributeError: Trainer object has no attribute loss_items

AttributeError: 'Trainer' object has no attribute 'loss_items'是由于Trainer对象中没有名为loss_items的属性而导致的错误。要解决这个问题，需要检你的代码，确保在Trainer类中定义了loss_items属性或者在使用该属性之前进行了正确的初始化。如果你已经定义了loss_items属性，但仍然出现该错误，可能是因为你没有正确地引用该属性。请检查你的代码，并确保正确地使用了loss_items属性。

AttributeError: list object has no attribute iloc

`iloc` is an attribute of a Pandas DataFrame or Series object, not a list object.

If you are trying to access a specific element within a list, you can use indexing to retrieve the element at a specific position. For example, if you have a list `my_list` and you want to retrieve the element at index 0, you can use `my_list[0]`.

If you are trying to use `iloc` on a DataFrame or Series object but are receiving this error, it may be because you are trying to apply it to a list object instead. Make sure you have properly converted your data to a Pandas DataFrame or Series before trying to use the `iloc` attribute.
