       出现这个问题是因为解释器找不到对应的文件。念了“妈咪妈咪轰”pwd后,发现问题所在:

%pwd 
ll

       pwd显示当前目录不是该文件所在的目录。这下明白了,使用咒语要谨慎,记得在念“妈咪妈咪轰”load前,要cd到该文件的目录下去�

       参�

       补充:Jupyter Notebook - sns.load_dataset加载文件错误解决方法

       seaborn模块中sns.load_dataset加载文件错误解决方法�

import seaborn as sns
data = sns.load_dataset("iris")

       出现错误�

URLError: <urlopen error [Errno 11004] getaddrinfo failed>

       出现原因�

       seaborn-data文件夹里面是空的,可以另外下载该文件夹的内容复制到该文件夹中�

       下载地址�

       https://github.com/mwaskom/seaborn-data

       下载位置�

       电脑上搜索seaborn-data文件夹,将下载下来的文件解压后全部放进seaborn-data文件夹,重新运行代码,出现结果�
