"double_scalars中遇到无效值"警告，可能是numpy [英] 'invalid value encountered in double_scalars' warning, possibly numpy

问题描述

在运行代码时，我偶尔会收到这些警告，通常是四个警告.我试图通过在某些语句之前和之后放置调试消息来定位源，以查明源.

As I run my code I get these warnings, always in groups of four, sporadically. I have tried to locate the source by placing debug messages before and after certain statements to pin-point its origin.

Warning: invalid value encountered in double_scalars
Warning: invalid value encountered in double_scalars
Warning: invalid value encountered in double_scalars
Warning: invalid value encountered in double_scalars

这是一个Numpy警告，什么是双标量?

Is this is a Numpy warning, and what is a double scalar?

我从Numpy中使用

min(), argmin(), mean() and random.randn()

我也使用Matplotlib

I also use Matplotlib

推荐答案

它看起来像是浮点计算错误.检查 numpy.seterr 函数以获取有关的更多信息发生的地方.

It looks like a floating-point calculation error. Check the numpy.seterr function to get more information about where it happens.
