int object has no attribute astype

这个错误表明在对象上调用astype()方法时发生了错误。astype()方法用于将NumPy数组中的元素转换为指定的数据类型。但是，普通的Python int对象不具备astype()方法。astype()方法是NumPy数组的方法。

如果您想将Python int对象转换为其他数据类型，可以使用int()函数将其转换为整数类型，然后使用相关的函数或方法将其进一步转换为所需的数据类型。

int object has no attribute pop

The error message "int object has no attribute pop" indicates that you are trying to use the pop() method on an integer object. The pop() method is a built-in method in Python that can only be used with certain data types such as lists, dictionaries, and sets.

For example, if you have a list called my_list and you want to remove the last item from it using the pop() method, you can do:

my_list = [1, 2, 3, 4, 5]
last_item = my_list.pop()

In this case, the pop() method will remove the last item from the list (5) and return it as a separate variable called last_item.

To fix the "int object has no attribute pop" error, you need to make sure that you are using the pop() method on the correct data type. If you are trying to use it on an integer or any other data type that does not support pop(), you will need to find an alternative way to achieve your desired outcome.

'int' object has no attribute 'astype'

'int' object has no attribute 'astype'是一个常见的错误消息它表示在Python中尝试使用astype()方法将整数类型转换为其他类型时出错。astype()方法是NumPy库中的方法，用于将数组的数据类型转换为指定的数据类型。

然而，整数类型（int）是Python内置类型，不具备astype()方法。astype()方法只能用于NumPy数组对象。

如果你想将整数类型转换为其他类型，可以使用内置的类型转换函数，例如int()、float()、str()等。这些函数可以将整数类型转换为相应的浮点数、字符串等类型。
