In this user guide, we will look at several possible causes that might be preventing the Warning widget from being detected, and then suggest some possible fixes that you can use to try to resolve the issue.
question:I also installed Python3 jupyter notebook with pip3 on MacOs 10.9.
ipywidgets import widgetsImport from IPython.display Displaytext = Widgets.Text ()Display (text)text.on_submit ('Hello')
sudo -H pip3 install ipywidgetssudo -H pip3 install Ipywidgets -upgradejupyter nbextension enable --py widgetsnbextension# restarted several computers.
[EnableNBExtensionApp] CRITICAL | Incorrect configuration occurred during initialization:[ActivateNBExtensionApp] CRITICAL | Unknown flag: '--py'
Please note that I have jupyter-nbextension on Mac, but I am running a request:
jupyter-nbextension enable --py widgetsnbextension
jupyter nbextension enable widgetsnbextension just throws an error and does nothing. The same error happened when I ran the code.
import ipywidgetsipywidgets .__ version__

How can I install widgets?
Do I need to install Java separately?
This is a duplicate component for me, probably because I need user config files and I want to switch between some virtual settings (not conda environments). The command using
jupyter notebook (with a small test notebook
tqdm.But tqdm_notebook ), I can reproduce this with a real notebook is more impractical. (Also, using some very
% matplotlib inline magic for the test notebook also fails to run there, although it appears to be in that notebook after doing a more complex place where it is used by
tqdm and results in a warning.)
As I mentioned @jasongrout , you can remove some male or female config files, then the command with
--sys-prefix may work. However, I never know what to remove. I end up with a
~ / .jupyter / jupyter_notebook_config.py file that basically contains a hashed password that most people want to keep using.
jupyter --paths with the
venv3 environment trigger produces the following output:
I would only remove
~ / .jupyter / nbconfig / notebook.json (which doesn't really matter
~ / venv3 / etc / jupyter / nbconfig / notebook .json )? Are there any packages that I need to reinstall using pip in their respective environments? Do the extensions "activate" anything other than simple Python money transfers, which I might also want to remove somewhere in ~ / .jupyter? If you remove
~ / .jupyter / nbconfig / notebook.json before running the
--sys-prefix command, the validation warning will not appear. Just running the command without an additional indicator works, then the level doesn't always work - I'm not a number.
