   Same Issue:

   Used this conda call to create the environment on a WSL Ubuntu:

   conda create --solver=libmamba -n rapids-23.12 -c rapidsai -c conda-forge -c nvidia \ rapids=23.12 python=3.10 cuda-version=11.8 \ jupyterlab napari dask-cuda dask-image matplotlib scikit-image anaconda::notebook

   then

   pip install ipyvolume

   import ipyvolume as ipv import numpy as np x, y, z, u, v, w = np.random.random((6, 1000))*2-1 ipv.quickquiver(x, y, z, u, v, w, size=5)

   1. Unistalling other widgets such as plotly, k3d etc.
   2. Restart the kernel.

   Import then worked, unfortunately the docs examples still do no show any plots. @T0bC, did it work for you in the end?

   I tried the same thing, but without success. I ended up using a different library. But I must admit that I'm still looking for a python library capable of displaying a 3D array of potentially 1000x1000x1000 voxels with alpha transparency. And the whole thing interactively in real time. I want to display a uCT dataset for segmentation processes without having to reduce the resolution. The software CTVox provided by the manufacturer seems to be able to do this, but unfortunately without pyhton integration.

   There you might run into hardware limitation and GPU would help a lot. Here is python CT framework with GPU support

   Other, general use viewer to consider can be napari

   I wanted zero install demos for students, so that it runs in notebooks/colabs. k3d worked for me in the end, but it is quite resource intensive, especially crashing colab NBs.

   I had this happen when loading the module failed due to #447 and I tried installing ipython_genutils by hand; after restarting the kernel the AttributeError error went away.
