我把你的图片转化成了代码，照抄了一下。见下面，发现没有错误提示。
import numpy as np
import matplotlib.pyplot as plt
from sklearn import svm
from sklearn.datasets import make_blobs
class_1_=7
class_2_=4
centers=[[0.0,0.0],[1,1]]
cluster_std=[0.5,1]
X_,y_=make_blobs(n_samples=[class_1_,class_2_],centers=centers,cluster_std=clusters_std,random_state=0,shuffle=False)
plt.scatter(X_[:,0],X_[:,1],c=y_,cmap="rainbow",s=30)
