Install breaks Qt

[sr67]

After installing with pipx inject I get qt error when I try to use vpype show e.g. "vpype random show" works fine, but after injecting hatched I get the error below. Thoughts?

$ vpype --version vpype 1.11.0a0

$ pipx inject vpype hatched injected package hatched into venv vpype done!

$ vpype random show QObject::moveToThread: Current thread (0x564880d67810) is not the object's thread (0x564880d74d20). Cannot move to target thread (0x564880d67810)

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/art/.local/pipx/venvs/vpype/lib/python3.9/site-packages/cv2/qt/plugins" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl.

I can't reproduce this. Can you provide more information on your OS, how you installed Python and pipx, etc.

Also, how did you install vpype in the first place? The current version is 1.10. Did you install vsketch as well?

Hi, sure. Thanks for having a look

OS: lsb_release -a No LSB modules are available. Distributor ID: Kali Description: Kali GNU/Linux Rolling Release: 2021.1 Codename: kali-rolling

Python: Don't recall how, or if, I installed, but... python --version Python 3.9.5

vpype: pipx install "vpype[all]" pipx inject vpype git+https://github.com/abey79/vsketch --include-apps pipx inject vpype hatched

I also injected the following, but only get this behavior when I inject hatched in any order in the process pipx inject vpype vpype-occult pipx inject vpype vpype-perspective pipx inject vpype vpype-embroidery pipx inject vpype vpype-vectrace pipx inject vpype git+https://github.com/serycjon/vpype-flow-imager pipx inject vpype vpype-pixelart

Can you provide the output of pipx inject --verbose vpype hatched (when starting clean)?

Edit: actually the whole thing would be interesting:

$ pipx uninstall vpype
$ pipx install --verbose vpype
$ pipx inject --verbose vpype hatched

Same error if I install just vpype[all] and hatched without vsketch. And vpype version remains 1.10.0 without vsketch install. show works before hatched install but not after.

OK, I think I've figured it out (and could have from your first message -- sorry for having you run circles 😅).

Try:

$ pipx runpip vpype uninstall opencv-python
$ pipx runpip vpype install opencv-python-headless

The base OpenCV installation includes a Qt distribution that appears to interfere with PySide2 in your case.

No worries, appreciate your help! Yes that seems to have solved my issue. Thanks so much.

Juste released hatched 0.2.0, which fixes this issue for good.
