jupyter notebook 无法连接到内核

Question

我想使用 jupyter notebook 但它不想连接到内核。 我尝试更新 anaconda 并从 anaconda 提示符启动 jupyter。 我收到此错误：

Traceback (most recent call last):
  File "C:\Users\felix\Anaconda3\lib\site-packages\tornado\web.py", line 1592, in _execute
    result = yield result
  File "C:\Users\felix\Anaconda3\lib\site-packages\tornado\gen.py", line 1133, in run
    value = future.result()
  File "C:\Users\felix\Anaconda3\lib\site-packages\tornado\gen.py", line 1147, in run
    yielded = self.gen.send(value)
  File "C:\Users\felix\AppData\Roaming\Python\Python37\site-packages\notebook\services\sessions\handlers.py", line 67, in post
    model = yield gen.maybe_future(sm.get_session(path=path))
  File "C:\Users\felix\AppData\Roaming\Python\Python37\site-packages\notebook\services\sessions\sessionmanager.py", line 170, in get_session
    return self.row_to_model(row)
  File "C:\Users\felix\AppData\Roaming\Python\Python37\site-packages\notebook\services\sessions\sessionmanager.py", line 209, in row_to_model
    raise KeyError
KeyError

将龙卷风降级到 4.5.3 似乎解决了它。 我可以通过 conda 提示符使用 jupyter。 但它仍然无法与 VS Code 一起使用。
