jupyter笔记本电脑未连接到内核

Question

我想使用jupyter笔记本，但它不想连接到内核。我尝试更新anaconda并从anaconda提示符启动jupyter。我得到了这个错误：

Traceback (most recent call last):
File "C:UsersfelixAnaconda3libsite-packagestornadoweb.py", line 1592, in _execute
result = yield result
File "C:UsersfelixAnaconda3libsite-packagestornadogen.py", line 1133, in run
value = future.result()
File "C:UsersfelixAnaconda3libsite-packagestornadogen.py", line 1147, in run
yielded = self.gen.send(value)

将龙卷风降级到4.5.3似乎解决了这个问题。我可以通过conda提示符使用jupyter。但它仍然不能与VS代码一起工作。
