我有一个不同植物物种的数据集,我将每个物种分成不同的物种np.array.
当试图从这些物种中生成高斯模型时,我不得不计算每个不同标签的平均值和协方差矩阵.
问题是:当np.cov()在其中一个标签中使用时,该函数会引发错误"'float'对象没有属性'shape'",我无法确定问题的来源.我正在使用的确切代码行如下:
covx = np.cov(label0, rowvar=False)
哪个label0是numpy ndarray of shape(50,3),其中列代表不同的变量,每行是不同的观察.

我正在尝试编写一些内容来将样条插值的Scipy函数应用于值数组.我的代码目前看起来像这样:
import numpy as np
import scipy as sp
from scipy.interpolate import interp1d
x=var
x1 = ([0.1,0.3,0.4])
y1 = [0.2,0.5,0.6]
new_length = 25
new_x = np.linspace(x.min(), x.max(), new_length)
new_y = sp.interpolate.interp1d(x, y, kind='cubic')(new_x)
但当它到达线
new_x = np.linspace(x.min(), x.max(), new_length)
我收到以下错误:
AttributeError: 'function' object has no attribute 'min'
到目前为止,谷歌搜索等没有发现任何我理解的内容.这是什么意思,我该如何解决？
第二个问题:如何一次输入多行代码？目前,如果我尝试复制整个内容然后将其粘贴到PyLab中,它只输入我的代码的顶行,所以我必须一次将整个内容粘贴到一行中.我怎么绕这个？
