在jupyter notebook中导入文件时发生了错误:
%load p2_test1.py
--------------------------------------------------------------------------- NameError Traceback (most recent call last) /usr/local/lib/python3.5/dist-packages/IPython/core/interactiveshell.py in find_user_code

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>
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
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,需要的朋友可以参考,希望对大家有帮助,关于解决jupyter 加载文件失败的介绍就到这,更多jupyter 加载文件失败内容,可以关注其他文章。
