Clearing browser cache helped here (but no rendering is visible yet)

vidartf commented 5 years ago

Clearing browser cache helped here (but no rendering is visible yet)

Not sure if I follow. Did clearing the cache make lab look normal again (and did it fix the errors in the server terminal)?

taiya commented 5 years ago

Yes, clearing the cache made it look normal, but when you execute the cell no graphics is displayed (while with notebooks it does)

How can one figure out how to resolve this?

vidartf commented 5 years ago

Do you have the @jupyter-widgets/jupyterlab-manager extension installed on lab? That tends to be a common missed point (can probably also be added to readme).

vidartf commented 5 years ago

Assuming this was fixed due to lack of response, closing. If there is still something unresolved here, please comment and I'll reopen as appropriate.

taiya commented 5 years ago

Not quite, just did not have time recently. Let me try this morning

taiya commented 5 years ago

Alright, gave it another try today (on a new server):

pip install jupyter
sudo jupyter labextension install jupyter-threejs

In a jupyter notebook, the following below produces the desired output: Screen Shot 2019-07-05 at 2 33 24 PM

While in jupyter lab it is not showing anything: Screen Shot 2019-07-05 at 2 35 30 PM

Snippet used (same ipynb file for both modes)

from pythreejs import *
import numpy as np
ball = Mesh(geometry=SphereGeometry(radius=1, widthSegments=32, heightSegments=24), 
            material=MeshLambertMaterial(color='red'),
            position=[2, 1, 0])

c = PerspectiveCamera(position=[0, 5, 5], up=[0, 1, 0],
                      children=[DirectionalLight(color='white', position=[3, 5, 1], intensity=0.5)])

scene = Scene(children=[ball, c, AmbientLight(color='#777777')])

renderer = Renderer(camera=c, 
                    scene=scene, 
                    controls=[OrbitControls(controlling=c)])
display(renderer)

What is the output of jupyter labextension list?

taiya commented 5 years ago

Ah, just saw again your note above, so looked it up and installed (I'll submit a pull request for the main readme if this is necessary)

sudo jupyter labextension install @jupyter-widgets/jupyterlab-manager

A change in the failure you get :)

Do you have any errors in the browser console (typically via Ctrl + Shift + J, or F12).

taiya commented 5 years ago

Oh yes, plenty :) Screen Shot 2019-07-08 at 9 38 26 AM

vidartf commented 5 years ago

Try to upgrade your Python pythreejs package (via conda or pip), as well as updating the labextension (jupyter labextension update --all).

taiya commented 5 years ago 
pip install pythreejs --upgrade
(python3) /mnt/erebus/dev/cvxnet: pip install pythreejs --upgrade
Requirement already up-to-date: pythreejs in /home/atagliasacchi/Envs/python3/lib/python3.5/site-packages (2.1.1)

Extension '@jupyterlab/git' already up to date
Extension 'jupyter-threejs' already up to date
Extension '@jupyterlab/celltags' already up to date

And while the above does not show versions, here they are

        jupyter-threejs v2.1.1  enabled  OK
        nbdime-jupyterlab v0.6.1  enabled  OK

Result of cell execution is the same:

Error displaying widget
vidartf commented 5 years ago

Hmm, seems to be an issue with the latest patch release of ipywidgets (https://github.com/jupyter-widgets/ipywidgets/issues/2491). It should be fixed once that issue is resolved and released.

taiya commented 5 years ago

Fingers crossed that's the case :) Let me know when you get the chance to test.

The issue with ipywidgets has been resolved, but there is now an issue with lab left to resolve this. Currently on vacation, so at least 2 weeks until I get to look at it. Note that upgrading to lab 1.0 should fix this issue.
