I got the similar problem, which shown in the following picture.

If I install trame-vtk and trame-vuetify, a new problem will be here:

my environment running with jupyter-notebook in docker container:
pip list| grep jupyter imjoy-jupyter-extension 0.3.0 jupyter-client 8.6.1 jupyter-core 5.7.2 jupyter-events 0.10.0 jupyter-server 2.13.0 jupyter-server-proxy 4.1.2 jupyter-server-terminals 0.5.3 jupyterlab-pygments 0.1.2 jupyterlab-widgets 3.0.10
pip list| grep trame trame 3.5.4 trame-client 2.16.5 trame-server 2.17.2 trame-vtk 2.8.5 trame-vuetify 2.4.3

pyvista 0.43.4

[jourdain]

probably you did not installed pyvista with the jupyter option (pip install "pyvista[jupyter]")

@jourdain
thanks for yoour reply. After installing with the jupyter option (pip install "pyvista[jupyter]"), I found the trame-vtk and trame-vuetify will be installed too. I would get the error

And I found some requests in F12 like "http://localhost:41349/index.html?ui=P_0x7f245835a970_0&reconnect=auto", a new port will be generated dynamically ? In container, the dynamic port cannot be forwarded to outside. Is there a solution? thks again

[savindi-wijenayaka]

@jxfruit For me keeping the normal pyvista installation with additional packages trame-vtk , trame-vuetify and ipywidgets fixed the issue. Had to restart the kernal though. However, I am using the VSCode to run the notebook.

[jourdain]

You can install trame-jupyter-extension or leverage the jupyter proxy server.

thanks for your comments! it works in JupyterLab browser. However, I found it cannot be shown on JupyterLab desktop. I am not sure if the problem is with the JupyterLab desktop.

[jourdain]

Might be an issue with message size on the websocket. You can try to bump trame>=3.6 which should fix message size.

Hi, I tried to upgrade the trame, but it still cannot be rendered.

Thanks for trying, I guess I'm not sure where that issue with JupyterLab desktop is coming from.

[jxfruit]

@jxfruit For me keeping the normal pyvista installation with additional packages trame-vtk , trame-vuetify and ipywidgets fixed the issue. Had to restart the kernal though. However, I am using the VSCode to run the notebook.

It works in local environment. However, I use it in k8s container, a specific port is necessary.

[jxfruit]

You can install trame-jupyter-extension or leverage the jupyter proxy server.

it looks like that does not work in Jupyter notebook. It get the same error

[jourdain]

When you are dealing with remote services, the default setting is not enough. Either you need to use jupyter-server-proxy or trame-jupyter-extension. With jupyter-server-proxy when not used within JupyterHub (which setup some ENV variable) you will need to set os.environ["TRAME_IFRAME_BUILDER"] = "serverproxy".

[lstngr]

Had the same issue with a conda install. Installing pyvista with conda install -c conda-forge pyvista jupyterlab ipywidgets trame did not automatically add trame-vtk as a dependency, and I was getting the same error as @YongcaiHuang.
After installing trame-vtk and trame-vuetify as suggested by @savindi-wijenayaka, I'm able to load the widgets in Jupyterlab.
