1、在需要文件间调用的文件夹下创建Ipynb_importer.py文件,文件内容为
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())
2、在python调用类写上 import Ipynb_importer
