module pandas has no attribute int

This error occurs when you try to use the `int` attribute on a pandas module, which does not exist. To resolve this issue, you should check your code and make sure you are calling the correct attribute or function from the pandas module.

For example, if you are trying to convert a pandas DataFrame column to integer, you should use the `astype()` function instead of the `int` attribute. Here is an example:

import pandas as pd

# create a DataFrame
df = pd.DataFrame({'A': ['1', '2', '3']})

# convert column 'A' to integer
df['A'] = df['A'].astype(int)

In this example, we are using the `astype()` function to convert the column 'A' to integer, instead of using the `int` attribute.

module pandas has no attribute dataframe

这个错误提示是因为你可能在代码中调用了pandas模块中不存在的dataframe属性。一般来说，pandas的DataFrame属性拼写是大写的"DataFrame"，而不是小写的"dataframe"。请检查代码拼写正确并重新运行程序。
