我安装了原子1.0,我想从Anaconda 3执行我的python 3.4.所有错误都是因为atom没有检测到我的anaconda包.我没有找到将python的设置更改为anaconda python的文件.

代码:

#/usr/bin/env python3
# -*- coding: utf-8 -*-


import numpy as np
import matplotlib.pyplot as plt
from sympy.solvers import *
from sympy import *
from matplotlib import rcParams


rcParams['text.latex.unicode'] = True
rcParams['text.usetex'] = True
rcParams['text.latex.preamble'] = '\usepackage{amsthm}', '\usepackage{amsmath}', '\usepackage{amssymb}',
'\usepackage{amsfonts}', '\usepackage[T1]{fontenc}', '\usepackage[utf8]{inputenc}'


f = lambda x: x ** 2 + 1
#f = lambda x: np.sin(x) / x

x = Symbol('x')
solucion = solve(x**2+1, x)

fig, ax = plt.subplots()
x = np.linspace(-6.0, 6.0, 1000)
ax.axis([x[0] - 0.5, x[-1] + 0.5, …

我正在尝试绘制具有 3 个平面的线性系统的解，解是点 (1,1,1) 我已经使用 point 命令绘制了该点，但我怀疑该点不在正确的位置:

ax.plot([1.], [1.], [1.], markerfacecolor=\'k\', markeredgecolor=\'k\', marker=\'o\', markersize=5, alpha=0.6)\n

谢谢\n好的，代码是：

我试图将 MessageBox 内容中的所有字体颜色更改为白色，但它也不会将 a href 字体颜色更改为白色。这是代码：

def MsgBox(self):
        qmsgBox = QMessageBox()
        qmsgBox.setStyleSheet('QMessageBox {background-color: #2b5b84; color: white;}\n QMessageBox {color: white;}\n QPushButton{color: white; font-size: 16px; background-color: #1d1d1d; border-radius: 10px; padding: 10px; text-align: center;}\n QPushButton:hover{color: #2b5b84;}')
        QMessageBox.about(qmsgBox, 'SuperPyQtCalculator',
            """<font color='white'><p><b>SuperPyQtCalculator</b></p>
