No graphics - Githubissues

cgarmstr commented 4 years ago

I'm obviously doing something really stupid, so my apologies.. I am using one of the sample programs on a Conda virtualenv with only numpy and ipyvolume installed: import ipyvolume as ipv import numpy as np N = 100 x, y, z = np.random.normal(0, 1, (3, N)) fig = ipv.figure() scatter = ipv.scatter(x, y, z) ipv.show()

I don't get any graphics, just

ipv.show() VBox(children=(Figure(camera=PerspectiveCamera(fov=45.0, position=(0.0, 0.0, 2.0), quaternion=(0.0, 0.0, 0.0, 1.0), scale=(1.0, 1.0, 1.0), up=(0.0, 1.0, 0.0)), camera_center=[0.0, 0.0, 0.0], controls=None, height=500, matrix_projection=[0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0], matrix_world=[0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0], scales={'x': LinearScale(max=2.449841813777466, min=-1.8161202829212062), 'y': LinearScale(max=2.4440524618404007, min=-2.408076104580802), 'z': LinearScale(max=1.6276369772492079, min=-2.0090489468131203)}, scatters=[Scatter(color_selected=array('white', dtype='<U5'), line_material=ShaderMaterial(), material=ShaderMaterial(), shader_snippets={'size': '\n'}, size=array(2), size_selected=array(2.6), texture=None, x=array([ 3.50099852e-01, -6.00288822e-01, 3.91342061e-01, 6.29243602e-01, 8.55550853e-01, -4.58904467e-01, 6.12929920e-01, 1.09489421e+00, -6.77522401e-01, 7.98317044e-01, 1.90140773e-01, -7.79114671e-01, ... 1.11541424e-02, -9.38330231e-01, -1.65141756e+00, 3.19769648e-01, 1.87715439e-01, 1.59439538e+00, -1.61753280e+00, -5.96089629e-01]))], scene=Scene(background=None, fog=None, overrideMaterial=None, quaternion=(0.0, 0.0, 0.0, 1.0), scale=(1.0, 1.0, 1.0), up=(0.0, 1.0, 0.0)), style={'axes': {'visible': True, 'label': {'color': 'black'}, 'ticklabel': {'color': 'black'}, 'color': 'black'}, 'box': {'visible': True}, 'background-color': 'white'}, width=400),))

When I use the same code in Jupyter Notebook I don't get any output as all.

Hey @cgarmstr, I have the exact same issue, let me know if you manage to find a solution! @maartenbreddels is there a bug?

cgarmstr commented 3 years ago

No, I never did find a solution. I just tried again and trying the same code in a Jupyter notebook give a long error message which began

Hi @cgarmstr & @cgarmstr

I don't know if this will help, but I had this problem when working in JupyterLab, it would just show: VBox(children=(Figure(camera=PerspectiveCamera(fov=45.0, position=(0.0, 0.0, 2.0), quaternion=....

It was because I had not installed all the required packages listed in the instructions. For JupyterLab I needed:

nodejs (I had to install through conda because it didnt do anything for me to install it through my regular package manager)
Jupyterlab widget manager
ipyvolume
jupyter threejs

Which i install with:

$ conda install -c conda-forge nodejs  # or some other way to have a recent node 
$ jupyter labextension install @jupyter-widgets/jupyterlab-manager
$ jupyter labextension install ipyvolume
$ jupyter labextension install jupyter-threejs

Maybe it is similar for standard jupyter notebooks.

Hope that helps!

cgarmstr commented 3 years ago

I thought you had the solution, but unfortunately not. I followed the official installation instructions like you have above. At the Anaconda prompt when I do jupyter labextension list I get JupyterLab v3.0.8 E:\Users\cecil\miniconda3\share\jupyter\labextensions bqplot v0.5.22 enabled ok jupyterlab-datawidgets v7.0.0 enabled ok @jupyter-widgets/jupyterlab-manager v3.0.0 enabled ok (python, jupyterlab_widgets)

Other labextensions (built into JupyterLab) app dir: E:\users\cecil\miniconda3\share\jupyter\lab ipyvolume v0.5.2 enabled ok jupyter-threejs v2.2.0 enabled ok

In a jupyter lab notebook import ipyvolume as ipv import numpy as np N = 100 x, y, z = np.random.normal(0, 1, (3, N)) fig = ipv.figure() scatter = ipv.scatter(x, y, z) ipv.show() results in Error displaying widget This is further than I've ever got before. Any further ideas to get me over the line? Many thanks!

Stefan-Schroder commented 3 years ago

I think you might be missing the nodejs lab extension. I'm not entirely sure how it works, but i think you have to have the python package of nodejs installed not just nodejs. The reason why I say this is because the output for my: jupyter labextension list is:

JupyterLab v3.1.0a2
/home/stefan/.local/share/jupyter/labextensions
        jupyterlab-datawidgets v7.0.0 enabled OK
        jupyter-matplotlib v0.8.3 enabled OK
        @axlair/jupyterlab_vim v0.13.0 enabled OK (python, jupyterlab_vim)

Other labextensions (built into JupyterLab)
   app dir: /home/stefan/.local/share/jupyter/lab
        @jupyter-widgets/jupyterlab-manager v3.0.0 enabled OK
        ipyvolume v0.5.2 enabled OK
        jupyter-threejs v2.2.0 enabled OK
        nodejs v0.0.0 enabled OK

so you have everything except the nodejs v0.0.0

And on my Ubuntu system it was not enough to just $ sudo apt install nodejs I had to install it through conda using $ conda install -c conda-forge nodejs

widgetti / ipyvolume
