如何解决 jupyter notebook 中的“TypeError ufunc 'isfinite'”

Question

我有一个关于类型的错误。它来自储料器。不知道代码哪里出错了

环境： 蟒蛇3.7 numpy 和其他库是最新的

TypeError                                 Traceback (most recent call last)

   2367         cls = MaskedArray
   2368     result = a.view(cls)

TypeError: ufunc 'isfinite' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

我希望展示完整的图表，但现在实际缺少一些事件。
