Python编译出现MemoryError问题，救

Question

问题遇到的现象和发生背景

用Jupyter学习纽约出租车运行情况分析建模时，在聚类的时候，运行下列代码出现MemoryError报错。

问题相关代码

kmeans = KMeans(n_clusters=15, random_state=2, n_init = 10).fit(loc_df)
loc_df['label'] = kmeans.labels_

loc_df = loc_df.sample(200000)
plt.figure(figsize = (10,10))
for label in loc_df.label.unique():
    plt.plot(loc_df.longitude[loc_df.label == label],loc_df.latitude[loc_df.label == label],'.',alpha = 0.3, markersize = 0.3)
    
plt.title('NewYork Clusters')
plt.show()

MemoryError: 

请问这个怎么解决吖

读取文件用的是

df = pd.read_csv('yellow_tripdata_2012-01.csv')

内存错误，一般是运行时内存占用超过了内存配置
