napari: Napari crash on Windows 10 - QT issue?
🐛 Bug
Hi all,
I’m a napari beginner and struggle in getting it to work on my Windows machine. It crashes while doing rather simple stuff
To Reproduce
Steps to reproduce the behavior:
- I installed napari using
pip install napariandconda install napari - I run this code in a python file:
import numpy as np
import napari
result = np.asarray([0, 1, 2, 3])
with napari.gui_qt():
viewer = napari.Viewer()
viewer.add_image(result);
This error pops up:

Expected behavior
Would be nice to see a napari window 😃

You are awesome and I assume my system is screwed up. However, every hint is appreciated!

@haesleinhuepf if you could collect system info from the students with failures, together with the stack trace, and put them in a repo/gist somewhere, that would be super useful. Unfortunately with FOSS + OpenGL the number of variables is so high that it’s really hard to track these things down. My number one thing is to try to get reliable failures from a brand new environment. Failures in long-lived environments with mixed pip, conda defaults, and conda-forge packages are to a first approximation impossible to debug, and even I just burn down the env and start again at that point.
Thank you for chiming in! We would absolutely love your help!
@haesleinhuepf
This is sometimes caused by terminals not being configured to handle unicode, as pointed out in this SO answer:
https://stackoverflow.com/a/12752945/224254
In your user’s case, it sees they would need to do
PYTHONIOENCODING=utf-8 jupyter notebook, although maybe it’s a bit different in Windows terminals — you possibly know a bit better than me there? =)Yep, I agree! Please keep raising them! =)
Confirmed! @jni just pointed me to that the 0.3.6 release is out and it works! ❤️
To stay organized, I could close this issue and open a new one when I hit another issue on windows?
Possibly fixed by #1445 ? Which will be in the imminent 0.3.6 Release
Alright, here you go: A
UnicodeDecodeError(related to vispy as far as I can see) when importing napari in python: https://gist.github.com/haesleinhuepf/56d89fb999040f28415c03867c96cf83Thanks to Ryan 😃
Hey all,
just a little update on this issue and Windows compatibility: I ran a course on Napari with my students. Most of them run on Windows. Not sure how many of the 60 students really tried it, but 5 had issues with making Napari work on Windows. Various issues: Dll load failures, vispy issues, qt-error messages.
Is there a recommended way of doing this? I didn’t mange unfortunately 😔 I also had weird experience with differences between older anaconda installations and more recent mini-condas. Not sure if this is relevant.
I’m just saying: Interest on my side for getting Napari work reliably on Windows is very high. Would love to support you if I can. Let me know if I can help!
Cheers, Robert
that might be useful, thanks 😃
I struggle from time to time when switching between different machines and getting stuff like napari (but also pyopencl, gputools,…) to work. Thus, if you need someone who tests installation procedures on a couple of systems, let me know. Happy to help.
#1289
No, as the above instructions are for the workshop. We need instructions that will work in a generic environment (not just conda) with user-selected packages, not a small whitelist of stuff.
I’ll leave it open because we need the above to work! 😬 But I’m glad you have a working install now! 😊
