matplotlib库中scatter和plot_matplotlib scatterplot

import torch
import matplotlib.pyplot as plt
 
x=torch.unsqueeze(torch.linspace(-1,1,100),dim=1)
y=x.pow(2)+0.2*torch.rand(x.size())
 
# plt.scatter(x.data.numpy(),y.data.numpy()) #绘制散点
# plt.plot(x.data.numpy(),y.data.numpy())    #绘制过点的线
# plt.show()

scatter：(x, y, s=None, c=None, marker=None, cmap=None, norm=None, vmin=None, vmax=None, alpha=None, linewi
