很抱歉,根据提供的引用内容,我无法回答您的问题。因为在提供的引用中没有提到'isps'这个属性或者方法。但是,我可以为您解释一下AttributeError: 'list' object has no attribute 'astype'的含义和可能的原因。
AttributeError: 'list' object has no attribute 'astype'是一个常见的错误,通常发生在使用Pandas的DataFrame时。这个错误的原因是因为astype()方法只能用于Pandas的Series对象,而不是Python的列表对象。因此,当您尝试在列表对象上使用astype()方法时,Python会抛出AttributeError。
可能的解决方法是将列表对象转换为Pandas的Series对象,然后再使用astype()方法。您可以使用Pandas的Series()函数将列表转换为Series对象,例如:
```
import pandas as pd
my_list = [1, 2, 3, 4, 5]
my_series = pd.Series(my_list)
my_series = my_series.astype('float')
```
这将把my_list转换为Pandas的Series对象,并将其转换为浮点数类型。

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:
```python
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)
```
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:
```python
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:
```python
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
```
