遇到个小白常见的问题,发现度娘里面没有记录,*谷歌了下,解决问题,在此写个说明。

事情起因:

在jupyter notebook中导入文件时发生了错误:

%load p2_test1.py

错误信息:

---------------------------------------------------------------------------

  3589       raise valueerror(("'%s' was not found in history, as a file, url, "

  3591 
  3592     if isinstance(codeobj, str):
 
valueerror: 'p2_test1.py' was not found in history, as a file, url, nor in the user namespace.

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。

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。

解决jupyter加载文件失败的问题

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。

以上为个人经验,希望能给大家一个参考,也希望大家多多支持。如有错误或未考虑完全的地方,望不吝赐教。
