How to resolve TypeError:s objext can not be iterpreted as an int

Question

每当我单击鼠标时，我都尝试使用以下代码来计算距离，但我收到此错误：TypeError: 'numpy.float64' object cannot be interpreted as an integer 我曾尝试遵循此解决方案但没有与我合作：sudo pip install -U numpy==1.11.0


import matplotlib.pyplot as plt
from matplotlib.widgets import Cursor 
from numpy import random 
import numpy as np 
#import pyautogui 
import mplcursors
from math import sqrt

x1, y1=random.rand(2,100)
x2, y2=random.rand(2,100)

fig, ax= plt.subplots()
p, = plt.plot(x1,y1, 'o')
p2, = plt.plot( x2,y2, 'o')
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')




cursor=Cursor(ax, horizOn=True, vertOn=True, color='blue', linewidth=1.0)
def onclick(event):
    z1, r1 = event.xdata, event.ydata
    print(z1, r1)
    #return z1,r1

    a1= int(z1,r1)
    p1 = a1.split(",")
    p2 = a1.split(",")

    distance = sqrt( ((int(p1[0])-int(p2[0]))**2)+((int(p1[1])-int(p2[1]))**2) )

    print("distance between ",p1,"and", p2, "is",distance) 


fig.canvas.mpl_connect('button_press_event', onclick)

mplcursors.cursor(hover=True) 
plt.show()

Answer 1

你的代码似乎对我有用，或者到底是什么问题？

这不是你想要达到的输出吗？

Answer 2

我假设您希望能够单击两个点，并在单击第二个点后计算它们之间的距离。我修改了您的代码，使您能够存储 class 变量，您需要这些变量来跟踪第一次和第二次点击事件。

import matplotlib.pyplot as plt
from matplotlib.widgets import Cursor
from numpy import random
import mplcursors
from math import sqrt


class DistancePlot:
    def __init__(self):
        self.x1, self.y1 = random.rand(2,100)
        self.x2, self.y2 = random.rand(2,100)

        self.fig, self.ax = plt.subplots()
        self.p = plt.plot(self.x1, self.y1, 'o')
        self.p2 = plt.plot(self.x2, self.y2, 'o')
        self.ax.set_xlabel('X-axis')
        self.ax.set_ylabel('Y-axis')

        self.d1 = (0.0, 0.0)
        self.d2 = (0.0, 0.0)

        self.first_click = True

        cursor=Cursor(self.ax, horizOn=True, vertOn=True, color='blue', linewidth=1.0)

        self.fig.canvas.mpl_connect('button_press_event', self.onclick)

        mplcursors.cursor(hover=True)
        plt.show()

    def onclick(self, event):
        z1, r1 = event.xdata, event.ydata
        print(z1, r1)

        if self.first_click:
            self.first_click = False
            self.d1 = (z1, r1)
        else:
            self.first_click = True
            self.d2 = (z1, r1)
            distance = sqrt((((self.d1[0]) - (self.d2[0])) ** 2) + (((self.d1[1]) - (self.d2[1])) ** 2))
            print("distance between ", self.d1, "and", self.d2, "is", distance)

dp = DistancePlot()

这可以大大清理，但为了清楚地了解您的原始问题，我使用了您的大部分原始代码。

输出：

0.428774046828733 0.7279552011765266
