404 GET Errors When Trying to Run ipyvolume on Jupyter Notebook

[ternarysrche]

I'm trying to get the following code to work in Jupyter Notebook:

import ipyvolume as ipv
import numpy as np
N = 1000
x, y, z = np.random.normal(0, 1, (3, N))
fig = ipv.figure()
scatter = ipv.scatter(x, y, z)
ipv.show()

Yet when I run the code, no output is displayed, and the kernel freezes, unable to be shutdown and to run other codes, until I reload the page. Terminal displays the following warnings and nothing else:

[W 00:22:00.355 NotebookApp] 404 GET /nbextensions/widgets/notebook/js/extension.js?v=20230102002145 (::1) 22.960000ms referer=http://localhost:8888/notebooks/Documents/sttp/Untitled.ipynb

Other widgets from ipywidget work just fine, and I have ensured that all required extensions are enabled. How do I fix this problem? Thanks in advance.

Ipyvolume requires pythreejs, can you check if that works?

Thanks for the quick response! I have installed pythreejs, and after running jupyter nbextension list, it shows the following:

Known nbextensions:
  config dir: /Users/christopher/.jupyter/nbconfig
    notebook section
      jupyter-js-widgets/extension  enabled 
      - Validating: OK

However, pythreejs does not seem to work either. After I run the Geometry Examples on pythreejs's documentation page, it also displays nothing The terminal again outputs:

I have tried searching for a solution to this issue, but to no avail.

A quick update, I installed node using Homebrew, and updated all relevant libraries using pip. Now, I get With the error being:

The console error message is

With pythreejs 2.4.1 it seems to work now.
