ValueError：使用optimize.curve时，操作数不能与形状（0）（26）一起广播 [英] ValueError: operands could not be broadcast together with shapes (0) (26) when using optimize.curve

问题描述

我正试图为我的脚本生成的某些数据找到最合适的界线。这就是我所拥有的：

I'm trying to get a best fit line to some data my script generates. This is what I have:

import numpy as np
import scipy as sp
.
.
.
def func(x, a, b, c):
    return a*np.exp(-b*x) + c
popt, pcov = sp.optimize.curve_fit(func, numgelt, turnsG)

我一直收到此错误：

ValueError: operands could not be broadcast together with shapes (0) (26)

$ b $一起广播b

我检查了两个数组（numgelt和turnsG）的大小肯定相同。我还确保了条目是浮动的。谢谢！

I have checked and the two arrays (numgelt and turnsG) are definitely the same size. I've also ensured that the entries are float. Thank you!

推荐答案

我遇到了同样的问题，直到我意识到我一直在使用列表而不是Numpy数组。转换为数组对我来说已经解决了。

I had the same problem until I realized I had been using lists instead of Numpy arrays. Converting to arrays fixed it for me.
