如何获取 pandas FutureWarning 的堆栈跟踪

获取 pandas 未来警告的堆栈跟踪就像将它们转换为异常一样简单。以下是你可以这样做：

pandas_stacktrace.py

import warnings
warnings.filterwarnings(
    'error', '.*Dtype inference on a pandas object.*',
    FutureWarning,
)

import warnings
warnings.filterwarnings(
    'error', '.*Dtype inference on a pandas object.*',
    FutureWarning,
)

确保将消息过滤器替换为你感兴趣的消息。你还可以使用正则表达式匹配多个消息。
