jupyter notebook 文件的调用（调用.py文件或.ipynb文件）

参考文献： jupyter notebook的project管理——.ipynb中调用.py文件在jupyter notebook中调用.ipynb文件

调用 .py文件这两个文件在工程的同一个文件夹中

在这里插入图片描述 hello.py中的代码：

def hello(): print('say hello')

call_helper.ipynb中的代码：

from hello import * hello()

运行：在这里插入图片描述

这两个文件不在同一个文件夹中如果这两个文件夹在同一个工程目录下

在这里插入图片描述 hello.py文件位于utils文件夹中，内容和上述的相同。只需要将call_helper.ipynb中改为from utils.hello import hello

from utils.hello import * hello() 如果这两个文件夹不在同一个工程目录下

如call_helper.ipynb位于G:\PHD\jupyter，而hello.py位于G:\PHD\test\utils文件夹中。则需要在call_helper.ipynb中使用sys将目录 G:\PHD\test\utils 添加。

import sys sys.path.append(r'G:\PHD|test') from utils.hello import * hello()

在这里插入图片描述

调用.ipynb文件两个文件在同一个文件夹中

添加jupyter notebook解析文件首先，创建一个python文件，例如Ipynb_importer.py，代码如下：注意是python文件，.py。

import io, os,sys,types from IPython import get_ipython from nbformat import read from IPython.core.interactiveshell import InteractiveShell class NotebookFinder(object): """Module finder that locates Jupyter Notebooks""" def __init__(self): self.loaders = {} def find_module(self, fullname, path=None): nb_path = find_notebook(fullname, path) if not nb_path: return key = path if path: # lists aren't hashable key = os.path.sep.join(path) if key not in self.loaders: self.loaders[key] = NotebookLoader(path) return self.loaders[key] def find_notebook(fullname, path=None): """find a notebook, given its fully qualified name and an optional path This turns "foo.bar" into "foo/bar.ipynb" and tries turning "Foo_Bar" into "Foo Bar" if Foo_Bar does not exist. """ name = fullname.rsplit('.', 1)[-1] if not path: path = [''] for d in path: nb_path = os.path.join(d, name + ".ipynb") if os.path.isfile(nb_path): return nb_path # let import Notebook_Name find "Notebook Name.ipynb" nb_path = nb_path.replace("_", " ") if os.path.isfile(nb_path): return nb_path class NotebookLoader(object): """Module Loader for Jupyter Notebooks""" def __init__(self, path=None): self.shell = InteractiveShell.instance() self.path = path def load_module(self, fullname): """import a notebook as a module""" path = find_notebook(fullname, self.path) print ("importing Jupyter notebook from %s" % path) # load the notebook object with io.open(path, 'r', encoding='utf-8') as f: nb = read(f, 4) # create the module and add it to sys.modules # if name in sys.modules: # return sys.modules[name] mod = types.ModuleType(fullname) mod.__file__ = path mod.__loader__ = self mod.__dict__['get_ipython'] = get_ipython sys.modules[fullname] = mod # extra work to ensure that magics that would affect the user_ns # actually affect the notebook module's ns save_user_ns = self.shell.user_ns self.shell.user_ns = mod.__dict__ try: for cell in nb.cells: if cell.cell_type == 'code': # transform the input to executable Python code = self.shell.input_transformer_manager.transform_cell(cell.source) # run the code in themodule exec(code, mod.__dict__) finally: self.shell.user_ns = save_user_ns return mod sys.meta_path.append(NotebookFinder())
