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 a method provided by Pandas DataFrame and Series objects to access data using integer-based indexing. It seems that you are using it with a list object which does not have this attribute.

To resolve this error, you should check if you are working with a Pandas DataFrame or Series object when trying to use `iloc`. If you are working with a list object, you can access its elements using integer-based indexing directly, without using `iloc`.

Here is an example:

my_list = [1, 2, 3, 4, 5]
print(my_list[0])  # Output: 1
print(my_list[1:3])  # Output: [2, 3]

If you are working with a Pandas DataFrame or Series object, make sure to use the correct syntax for `iloc`. Here is an example:

import pandas as pd

df = pd.DataFrame({'a': [1, 2, 3], 'b': [4, 5, 6]})
print(df.iloc[0])  # Output: a    1\nb    4\nName: 0, dtype: int64
print(df.iloc[0, 1])  # Output: 4

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)
