python报错：FutureWarning: Setting an item of incompatible dtype is deprecated and will raise in a future error of pandas.........has dtype incompatible with float32, please explicitly cast to a compatible dtype first.

不影响程序运行，只是不断弹出影响输出查看。

认为是无关紧要的小问题，不关乎结果正确与否，

采取暴力消除的方式

import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)

完美解决！
