itkwidgets.view(image) nothing show

[zhangjipinggom]

Problem I tested the the itkwidgets example 3DImage.ipynb

no error pops, but after view, nothing shows out.

What I have tried I saw the problem previously asked below, but it doesn't solve my problem. I have tried itkwidget 0.32.1, 0.27.4 and 0.29.0, it still doesn't work. itkwidget view not working in Jupyter Notebook #310

Environment python: 3.8.1 itkwidgets: 0.32.1 jupyter-notebook: 6.3.0

please help. Thanks a lot.

Are there image intensities in the range 4000-17000? Perhaps try leaving off all arguments and see if an image is displayed:

view(image)

I have the same issue. When I run the following in Jupyter notebook there is no output.

import itk
from itkwidgets import view

image = itk.imread('Capture.PNG')
view(image)

I'm using python 3.6.9, itkwidgets 0.32.1, jupyter 1.0.0 on Ubuntu 18.04.5

[parap1uie-s]

Same issue and same console log.

[burnpanck]

same error here

[burnpanck]

The Jupyter Notebook server shows a 404 for GET /static/itkwidgets.js?v=20211029173136. Could it be that the js-side of itkwidgets needs to be installed similarly to the jupyter lab extensions? jupyter nbextension install itkwidgets however fails with FileNotFoundError itkwidgets.

[burnpanck]

It seems like the following two lines do the trick:

jupyter nbextension install --py itkwidgets
jupyter nbextension enable --py itkwidgets

[Interesting6]

It seems like the following two lines do the trick:

jupyter nbextension install --py itkwidgets
jupyter nbextension enable --py itkwidgets

same situation, same solution, cheer up! the jupyter lack itkwidgets extension.

jupyter nbextension install --py itkwidgets

The same error, but it does not work in my code.

[jxfruit]

still problem in python3.8.5 itkwidgets 1.0a23 jupyter-notebook 6.4.3, any solutions?

[bnmajor]

@jxfruit I would use the latest release: pip install itkwidgets[all]>=1.0a49. I will open a PR to update docs to reflect this version number.

[jxfruit]

@jxfruit I would use the latest release: pip install itkwidgets[all]>=1.0a49. I will open a PR to update docs to reflect this version number. @bnmajor thanks for your reply. I had tried use the latest version 1.0a49, but it is useless. And I found I must enable the imjoy plugin, after enabled it, I got the other error in frontend console: "Timeout error: failed to connect to the plugin", I got the errors in terminal: [IPKernelApp] ERROR | No such comm target registered: jupyter.widget.control [IPKernelApp] WARNING | No such comm: ad92f2a7-b69f-4688-b18d-ac2740b46f69 the picture shown is the result in notebook

[bnmajor]

I tested the Hell3DWorld example locally with a new environment - Python 3.8, Jupyter Notebook 6.4.3, itkwidgets 1.0a49 and everything worked well for me.

You should not need to enable the ImJoy plugin through the UI - are you installing with itkwidgets[all]? If you can share the notebook you are testing with (or a simplified version of it) I would be happy to test it out.

@bnmajor local environment is fine. Sorry for my negligence. I use the itkwidgets with vtk in k8s container. I have tried use xvfb, but it still a problem. So is there a solution in k8s container? thks
