I'm unable to launch the Jupyter on Anaconda. I'm using windows, how can I get rid of this error? The error says:
Traceback (most recent call last):
File "C:\Users\User\anaconda3\Scripts\jupyter-notebook-script.py", line 6, in
from notebook.notebookapp import main
File "C:\Users\User\anaconda3\lib\site-packages\notebook\notebookapp.py", line 64, in
raise ImportError(_("The Jupyter Notebook requires tornado >= 5.0, but you have %s") % tornado.version)
ImportError: The Jupyter Notebook requires tornado >= 5.0, but you have 4.5.3
You can probably remove it off your system then put it back on with for python
sudo apt-get remove python-tornado
sudo pip install tornado
similarly you could run it for python 3 if neccesary
sudo apt-get remove python3-tornado
sudo pip3 install -U tornado
or you could try the following to upgrade tornado
sudo pip install tornado --upgrade
you said:
I'm unable to launch the Jupyter on Anaconda.
you can update it from Anaconda.Navigator
tornado 4.5.3
click on the check then choose
make for a specific version --> 6.1
go to Anacondas' home page then ran jupyter [install -> launch ] done
Try uninstalling tornado with: (pip uninstall tornado) for some reason after deleting my tornado 4.5.3 it automatically updated to Version 6. and started working perfectly fine, I don't know the exact reason, possibly a missing dependency was auto installed I guess. whatever it is, this worked for me.
