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:
%load p2_test1.py
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: in NameError: name 'p2_test1' is not defined During handling of the above exception, another exception occurred: ValueError Traceback (most recent call last) in ----> 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 in load(self, arg_s) /usr/local/lib/python3.5/dist-packages/IPython/core/magic.py in (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 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:
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
