Question

我想在本地目录中加载Jupyter Notebook Server Extension：

server_ext/
|__  __init__.py
|__  extension.py

extension.py

from notebook.utils import url_path_join
from notebook.base.handlers import IPythonHandler

class HelloWorldHandler(IPythonHandler):
    def get(self):
        self.finish('Hello, world!')

def load_jupyter_server_extension(nbapp):
    """
    nbapp is istance of Jupyter.notebook.notebookapp.NotebookApp
    nbapp.web_app is isntance of tornado.web.Application - can register new tornado.web.RequestHandlers
    to extend API backend.
    """
    nbapp.log.info('My Extension Loaded')
    web_app = nbapp.web_app
    host_pattern = '.*$'
    route_pattern = url_path_join(web_app.settings['base_url'], '/hello')
    web_app.add_handlers(host_pattern, [(route_pattern, HelloWorldHandler)])

我从包含server_ext的目录运行以下命令：

jupyter notebook --NotebookApp.server_extensions="['server_ext.extension']"

但我得到错误“没有模块命名扩展名”。为了让Jupyter / python会话识别模块的路径，我有什么必须做的吗？

想出来 -

事实证明，Jupyter Notebook对importlib.import_module的调用设置了package = None，这意味着相对路径不起作用。

作为一种解决方法，可以修改〜/ .jupyter / jupyter_notebook_config.py脚本以将本地目录附加到PYTHONPATH，以便可以找到该模块。

import sys
sys.path.append("C:\\Users\\eric\\server_ext")

c.NotebookApp.server_extensions = [
    'extension'
]

加载Jupyter Server Extension时找不到模块
