sorry @Panzer-vor-08. I have developed/tried nglview with VSCode so I don't know the answer.

does below work for you?

from ipywidgets import Text
Text("HELLO")

[Panzer-vor-08]

it seems to work properly

[OWissett]

I too have this problem...

[OWissett]

I am running Python 3.11.7, in a mamba 1.4.2 env, using jupyter 1.0.0, ipywidgets 8.1.1

[hainm]

sorry guys, I have 0-knowledge about VSCode.😭

[watanabeaisora35]

I also had this problem in VScode.

"Error: No version of module nglview-js-widgets is registered"
Anyone knows how to solve this problem?

[OWissett]

I found as a work around, just use a different protein viewer package. I am using py3dmol which seems to work better with VSCode

[hnguyentt]

I faced the same problem. Has anyone had a workaround for this?

[sH4MbLe5]

Same here...

[kizzhang]

I managed to resolve this issue.
I downgraded ipywidgets and nglview.
Now my linux system has ipywidgets=8.0.6 and nglview=3.0.6.

[Abhishaike]

Having the exact same problem, the above fix here: #1085 (comment) did not work for me

[Heezch]

I have also encountered the same issue... at some point it worked to indeed downgrade to nglview==3.0.8 ipywidgets==8.1.1 jupyterlab>4 , but this does not seem stable...

Small update:

See below a combination of versions that seem to work in VScode on MacOS (ARM silicon). After creating a new env also completely quit the VScode application and then restart before trying the import ngvliew nglview.demo()

python 3.12.3
jupyterlab 4.1.5
ipykernel 6.29.3
ipython 8.24.0
ipywidgets 8.0.6
nglview 3.0.6
