Question

我今天更新了我的conda环境。以前，我可以从终端启动jupyter实验室。更新后（包括安装theano，但我猜这是不相关的），我得到以下错误，我不明白：

marcel@flaptop:~$ jupyter lab
Traceback (most recent call last):
File "/home/marcel/anaconda3/bin/jupyter-lab", line 7, in <module> from jupyterlab.labapp import main
File "/home/marcel/anaconda3/lib/python3.6/site-packages/jupyterlab/labapp.py", line 7, in <module> from notebook.notebookapp import NotebookApp, aliases, flags  
File "/home/marcel/anaconda3/lib/python3.6/site-packages/notebook/notebookapp.py", line 45, in <module> ioloop.install()
File "/home/marcel/anaconda3/lib/python3.6/site-packages/zmq/eventloop/ioloop.py", line 210, in install assert (not ioloop.IOLoop.initialized()) or  AttributeError: type object 'IOLoop' has no attribute 'initialized'

有谁知道这里发生了什么？t

Answer 1

似乎是Tornado版本5.这里有讨论： Install Jupyter Notebook on Miniconda

ini_set('allow_url_include', 'On');

为我修好了，如上面的链接所示。
