I've just remembered something. This might do with locale. My decimal separator is comma, not a dot. I'll try reset LC_NUMERIC to C.utf-8 and reproduce. Qt + sscanf + LC_NUMERIC is problematic and cura uses Qt. https://stackoverflow.com/questions/20555696/why-does-qt-change-behaviour-of-sscanf
(cannot test it immediately unfortunately, reporting from my cell phone, as this idea came up while I couldn't sleep)

Yes, that's the plan. I'm working on a release as we speak :)

Hmm, that's unfortunate.
Would you be able to attach the stl file so I can check what's wrong? It seems your file uses a slightly different format which breaks the parser.

I've generated the stl file using openscad. I've attached both the .scad that was used to generate the .stl
file and the .stl file itself. It should only be a simple cube.
I am not completely sure if there is an issue with the file itself, since I can load the file without problem when I do not generate a MPL figure before.

I'm still not sure what's causing it exactly, I'm not able to reproduce it myself but I suspect that matplotlib is somehow wrapping the file handlers.
For the time being it makes no sense to me... perhaps a namespace clash somehow but I have no idea what.
Are you certain you are running the latest version? It seems the line numbers in your stacktrace don't line up with the current release: https://github.com/WoLpH/numpy-stl/blob/develop/stl/_speedups.pyx#L132

I was running version numpy-stl 2.0.0, however after upgrading to version 2.2.0 I still end up with the same error message:

I hope the lines make more sense now. But stl.__about__.__version__ returns 2.2.0.

Can you tell me a bit more about what software versions you are running?
Linux, Windows, osx and version?
Matplotlib version
Python version and release (2.7 regular, pypy, etc.)?
from numpy-stl.

Probably should have done this in the first post:
OS: Xubuntu 14.04 (3.13.0-61-generic)
Python: Python 2.7.6 standard installation
Matplotlib: 1.4.3
Cython (if this is any important): 0.20.1post0
Numpy: 1.12.1
from numpy-stl.

For the time being I've created a new release which falls back to the regular ascii version.
Thinking about it I may know what the issue was, I was using universal-wheels which work great if you're only running pure Python. The speedups might have been broken for everyone not running OS X

Wild guess, but could it have something to do with the back-end matplotlib is using (interactive or non-interactive and some interference)?
I cannot recreate the issue unfortunately. :<

The problem seems to have resolved itself, noone appears to be able to reproduce it anymore so that's arguably a good thing...
If anyone has the problem again let me know and I can reopen. Linked issue: Ultimaker/Cura#1785

It is once again a very long shot, but as the issue is not reproducible to me, or to Miro when not using Cura, I'll ask about this long shot. :)
Is it possible that the Cura application tries to open a dialog, and this dialog sees part of the ASCII file as a user response; effectively consuming data which should be loaded as part of the stl?
It displays a message about a mutually dependent binding of some textinput, where QML textinput:
The TextInput type displays a single line of editable plain text.
TextInput is used to accept a line of text input
That is really the only thing I can think of; and would also have a vague relation to the earlier link to a matplotlib plot (Qt backend).
UPDATE 2:
Found a sort of similar object and an explanation of what can go wrong during the binding loop..

commented on August 25, 2024
The stacktrace does offer me something useful, it seems it's actually trying to load the file as a binary which is useless when using from_multi_file because binary files cannot contain multiple STLs.
By default the MODE is set to ASCII so the actual error is hidden right now. I'll change the code to raise when it's in ASCII mode since it shouldn't try to fall back to binary unless it's in AUTOMATIC mode.

It appears to indicate that it is only getting stuck on the third facet. Might be nice for purposes of narrowing it down to test a few outlier cases:
@hroncok : 1. what happens if you try to read the same file, but with only the first 2 facets? How do the loaded vertex coordinates look for those 2 facets?
2. what happens if you remove the third facet? I'm actually secretly hoping for it to raise RuntimeError: (0, "Can't read vertex (19:b'vertex 0 2.22045e-15 -10')") if you strictly remove the third facet. :)

absolutely perfect!
That means the problem is in the scientific notation in the middle vertex coordinate. Alas we didn't get to see what happens with the scientific notation at the 3d coordinate, but we narrowed it down.
if sscanf(line, '%*s %f %f %f\n',
facet.v[i], facet.v[i]+1, facet.v[i]+2) != 3:
raise RuntimeError(state.recoverable,
'Cannot read vertex (%i:%s)' % (state.line_num, line))
is thus not compatible with the consecutive numbers "2.22045e-15 -10" here.
My mastery of C and methods of testing in this direction are so-to-say ... well... limited, but it should be reproducible now.

It seems to be compiler dependent as far as I can gather: https://stackoverflow.com/questions/24342982/reading-scientific-notation-in-c
It could also be size related, perhaps %lf will work in more cases but I'll try with %e

Thanks for linking the bug report, @hroncok .
It's really odd though: I can load the file from the bug report just fine, and I'm actually the one maintaining the Cura packages in Debian.
I should note though that I'm testing with Cura built locally on my workstation, so perhaps there is something different about the build environment?

Yes, possibly. So far I've not been able to reproduce it either...
That certainly makes it challenging to fix

Same goes to cura, setting LC_NUMERIC to C.utf-8 makes the crash go away.

That explains why I've been completely unable to reproduce it, I have my default set to C.utf-8
Excellent work @hroncok! Thank you so much :)

This was not closed, as there was no commit with "Fixes #52". Let's close it after a release?

I've got a few small issues getting the tests to run on my laptop (osx), which effectively results in not being able to deploy a new release. For safety I have a auto-test system in place as a pre-deploy step.

I'm giving it the old college try to get it working. If it turns out to be problematic I'll skip it :)
No worries, I'll push out a release today either way

It turned out to be a weird local error. After starting with a clean project it worked out just fine :)
Thanks again @hroncok
