Segmentation fault on 3d rendering cube fits data

[Mixpap]

While i tried the 3d volume rendering for a 3d cube fits data glue crashed with:

anaconda3/lib/python3.6/site-packages/glue/core/component.py:79: FutureWarning:

Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result.

Segmentation fault (core dumped)

The 2d slices work as expected.

@Mixpap - what kind of 3D data are you using, and how large is it?

[Mixpap]

Its a 627x497x61 fits file (82.4 Mb)

I thought i had old version issues (i am using conda) so i downloaded everything (matplotlib, numpy etc) from conda forge. Now, glue doesn't even start giving

@Mixpap - sorry for the delay, if you are still running into the segmentation fault, could you try starting up glue using:

python -X faulthandler -m glue.main

as this will provide more information about the cause of the crash.

Hi @astrofrog,

>>> python -X faulthandler -m glue.main

Hi,

I've also encountered this problem. I started Glue using python -X faulthandler -m glue.main It returned: `Fatal Python error: Segmentation fault

Any idea?

I am also encountering the segfault when trying to use the 3D plugins. Would appreciate help with this ticket.
