Failing to import Texture3D or TextureEmulated3D

[pbl007]

Hello,

I am getting the following error while trying to import Texture3D

Python 3.7.12 | packaged by conda-forge | (default, Oct 26 2021, 06:08:53) 
Type 'copyright', 'credits' or 'license' for more information
IPython 7.30.1 -- An enhanced Interactive Python. Type '?' for help.

In [1]: from vispy.visuals.volume import Texture3D
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-6d0e9705592c> in <module>
----> 1 from vispy.visuals.volume import Texture3D

ImportError: cannot import name 'Texture3D' from 'vispy.visuals.volume' (/opt/miniconda3/envs/ClearMap/lib/python3.7/site-packages/vispy/visuals/volume.py)

This is the version of vispy installed in the specific environment (needed for frozen app)
vispy 0.9.4 py37hc59e7c5_0 conda-forge

Help will be much appreciated!
Thanks in advance.

Is there a reason you are importing the Texture3D class from the volume module instead of the vispy.gloo module/subpackage? The VolumeVisual no longer uses the Texture3D class directly but instead uses a higher-level wrapper class so it no longer imports Texture3D directly.

Hi. The app code is not under my control.... is there a chance to solve the issue for the specific version of vispy (0.9.4)?
Thanks in advance!

The app code is not under my control....

But what aspect is under your control by which means this issue may be fixed?

[pbl007]

All code is open so I could, in principle, branch and modify but the same env/code works for me in a Linux cluster, now installing in another server completely fails.

@pbl007 You can downgrade vispy to <0.7.0 because I think this was changed in 0.7.0. Is the code you are using on github or gitlab? Can a pull/merge request be made? The fix for using that code as-is is to downgrade vispy. The fix for that project long term is to fix the import which would work for all versions of vispy (pre and post 0.7).

This is what indeed what I will do! Thanks!
