Point cloud cannot be displayed successfully
I use jupyter-lab and cannot successfully show that the point cloud has only a string of prints. I don't know if it is because of the code or because of a problem with the environment of jupyter-lab. I want to show pointcloud but it just give me like this prints no pointcloud view:

Hola. It seems like an issue with the jupyter lab environment. Please check the comments in #187 to see if your problem is related with that.
Specifically: https://github.com/daavoo/pyntcloud/issues/187#issuecomment-400776966
Thank you for your reply．Point clouds can be displayed normally in notbook．But not in the lab, only 2d pictures can be displayed in the lab．
but when I execute command 'jupyter labextension install @jupyter-widgets/jupyterlab-manager' and 'jupyter lab build' give me the same error:'NameError: name 'CoreConfig' is not defined' I used Ubuntu16.04
It looks like there is an issue with the nodejs version installed. See:
https://github.com/quigleyj97/jupyterlab-spreadsheet/issues/19
Following the comments, could you run:
conda install -c conda-forge nodejs
To see if that uptades your node version and resolves the problem?
I updated nodejs to the latest，And successfully executed:
'jupyter labextension install @jupyter-widgets/jupyterlab-manager'.
Now its different befor.its succellfully display buttons:
'Point size:-------------- 0.01' and 'Background color: black'
but there is still no pointcloud its show me the error:
'Error displaying widget: model not found'.

I also have the same issue - extension is enabled, and shows basic controls but plotting fails with message "Error displaying widget: model not found"
