I installed Miniconda and I'm trying to use Jupyter Notebook with it but haven't been able to do so. After installing miniconda I ran the jupyter notebook
command on my terminal and jupyter wasn't installed.
I went ahead and installed it with the conda install jupyter
. However, I once again ran jupyter notebook
on my terminal and got the following console error:
Emilios-MacBook-Pro:documents emilioramirezeguia$ jupyter notebook Traceback (most recent call last): File "/Users/emilioramirezeguia/miniconda2/bin/jupyter-notebook", line 7, in from notebook.notebookapp import main File "/Users/emilioramirezeguia/miniconda2/lib/python2.7/site-packages/notebook/notebookapp.py", line 45, in ioloop.install() File "/Users/emilioramirezeguia/miniconda2/lib/python2.7/site-packages/zmq/eventloop/ioloop.py", line 210, in install assert (not ioloop.IOLoop.initialized()) or \ AttributeError: type object 'IOLoop' has no attribute 'initialized'
Any idea how to fix this?
Thank you
3.1. To launch Jupyter Notebook App: Click on spotlight, type terminal to open a terminal window. Enter the startup folder by typing cd /some_folder_name . Type jupyter notebook to launch the Jupyter Notebook App The notebook interface will appear in a new browser window or tab.
This problem has just happened to me as well. My older anaconda environments seem to be working fine but the environments I have created today seem to have this exact issue which throws AttributeError: type object 'IOLoop' has no attribute 'initialized'
.
It seems to be because of the latest release of tornado==5.0
which released either today or yesterday. I reverted back to the last stable version i.e. tornado==4.5.3
and it worked.
Here's the solution
pip uninstall tornado pip install tornado==4.5.3
Miniconda is OK but Anaconda is recommend.
I have the same issue and thanks Nitred give the right solution.
It seems that jupyter notebook does not support the tornado 5.0. So downgrade as the following:
pip uninstall tornado pip install tornado==4.5.3
