diff() got an unexpected keyword argument 'axis'

As an AI language model, I can explain that the error message "diff() got an unexpected keyword argument 'axis'" is raised when the `diff()` function in Python is called with the `axis` argument, which is not a valid argument for this function. `diff()` is used to calculate the difference between consecutive elements of a numeric array or a pandas DataFrame. It does not have an `axis` parameter.
To fix this error, you should remove the `axis` parameter from the `diff()` function call. If you need to perform the difference operation along a specific axis, you can use other functions such as `numpy.diff()` or `pandas.DataFrame.diff()` that do have an `axis` parameter.
