这篇教程解决jupyter加载文件失败的问题写得很实用，希望能帮到您。
遇到个小白常见的问题，发现度娘里面没有记录，翻墙谷歌了下，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： 错误信息：---------------------------------------------------------------------------NameError Traceback (most recent call last)/usr/local/lib/python3.5/dist-packages/IPython/core/interactiveshell.py in find_user_code(self, target, raw, py_only, skip_encoding_cookie, search_ns) 3586 try: # User namespace-> 3587 codeobj = eval(target, self.user_ns) 3588 except Exception: <string> in <module> NameError: name 'p2_test1' is not defined During handling of the above exception, another exception occurred: ValueError Traceback (most recent call last)<ipython-input-1-e4e531e2ca85> in <module>----> 1 get_ipython().run_line_magic('load', 'p2_test1.py') /usr/local/lib/python3.5/dist-packages/IPython/core/interactiveshell.py in run_line_magic(self, magic_name, line, _stack_depth) 2285 kwargs['local_ns'] = sys._getframe(stack_depth).f_locals 2286 with self.builtin_trap:-> 2287 result = fn(*args,**kwargs) 2288 return result 2289 <decorator-gen-47> in load(self, arg_s) /usr/local/lib/python3.5/dist-packages/IPython/core/magic.py in <lambda>(f, *a, **k) 185 # but it's overkill for just that one bit of state. 186 def magic_deco(arg):--> 187 call = lambda f, *a, **k: f(*a, **k) 188 189 if callable(arg): /usr/local/lib/python3.5/dist-packages/IPython/core/magics/code.py in load(self, arg_s) 333 search_ns = 'n' in opts 334 --> 335 contents = self.shell.find_user_code(args, search_ns=search_ns) 336 337 if 's' in opts: /usr/local/lib/python3.5/dist-packages/IPython/core/interactiveshell.py in find_user_code(self, target, raw, py_only, skip_encoding_cookie, search_ns) 3588 except Exception: 3589 raise ValueError(("'%s' was not found in history, as a file, url, "-> 3590 "nor in the user namespace.") % target) 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。 参考 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 snsdata = 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。 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51zixue.net。如有错误或未考虑完全的地方，望不吝赐教。
