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

AttributeError: 'list' object has no attribute 'ListedColormap' 错误通常发生在使用matplotlib库时。这个错误的原因是你试图在一个列表对象上调用ListedColormap属性，而列表对象并没有这个属性。要解决这个问题，你应该确保你在调用ListedColormap属性的时候使用正确的对象。

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.

AttributeError: list object has no attribute squeeze

AttributeError: list object has no attribute squeeze是因为在列表对象上调用squeeze方法，而列表对象并没有squeeze方法。squeeze方法是numpy数组对象的方法，用于从数组的形状中删除单维度条目。如果想要使用squeeze方法，需要将列表对象转换为numpy数组对象。

以下是一个例子：

import numpy as np

# 将列表转换为numpy数组
a = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
print(a)

# 使用squeeze方法删除单维度条目
b = np.squeeze(a)
print(b)
