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.

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．

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