# 运用散点图对数据分布得到直观的认识 import numpy as np import matplotlib.pyplot as plt # 设计 x, y 轴 n = 10000 x = np.random.randn( n ) # 随机值 y = np.random.randn( n ) # 显示散点图 colors = ['b','r','g','y','k','m'] plt.scatter(x, y, c = colors, marker = 'p', alpha=0.5 ) pl
首先都得导模块. import numpy as np import pandas as pd import matplotlib.pyplot as plt from pandas import Series,DataFrame 一.绘制单线图 1,直线图 x=[1,2,3,4,5] y=[2,4,6,8,10] plt.plot(x,y) 2,抛物线 x = np.arange(-np.pi,np.pi,0.2) y = x**2 plt.plot(x,y) 3,正弦图 x = np.ara
import torch from torch.autograd import Variable import torch.nn.functional as F import matplotlib.pyplot as plt x=torch.unsqueeze(torch.linspace(-1,1,100),dim=1) #torch.linspace本身是一维向量,unsqueeze是增加维度,把一维化为二维 y=x.pow(2)+0.2*torch.rand(x.size()) #0.2*
JupyterLab绘图 喜欢python的同学,可以到 https://v3u.cn/(刘悦的技术博客) 里面去看看,爬虫,数据库,flask,Django,机器学习,前端知识点,JavaScript,还有各种练习题,在里面可以自由提问.接触python时间不长,想扩展知识面,了解更多知识的朋友,欢迎你的加入 友情链接: https://v3u.cn/ #需要导的包 from numpy import random import pandas as pd import numpy as n
