[BUG] {Error running python3 depthai_demo.py} #568

Open JaCoHSU opened 2 years ago

JaCoHSU commented 2 years ago

Hey guys,

My Oak-D Lite just arrived. I wanted to test it with depthai. What I did is this:

git clone https://github.com/luxonis/depthai.git
cd depthai
python3 install_requirements.py

Installation seemed to work without errors but when I executed this: python3 depthai_demo.py

I get the following error. Does anyone know how to fix it or why this error occured?

 python3 depthai_demo.py

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/falke/.local/lib/python3.6/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.

@JaCoHSU It's possible some packages need to be installed for Qt on Linux, these added here: https://github.com/luxonis/depthai-python/commit/79f47c7c5e4dc55fcafdece9cca684b12702e03f

You can install with apt install, or just run the command to install all dependencies:

sudo wget -qO- https://docs.luxonis.com/install_dependencies.sh | bash

(from https://docs.luxonis.com/projects/api/en/latest/install/?#ubuntu)

@alex-luxonis thanks for the quick response.

I ran the install_dependencies.sh

and when i run python3 depthai_demo.py I get the same error as posted before. Any idea?

alex-luxonis commented 2 years ago

What OS is this on, Ubuntu 18.04? I see there Python 3.6 (default on 18.04).

It's possible to run also without the Qt GUI, with the old OpenCV interface, but most of the options there need to be set from command line: python3 depthai_demo.py -gt cv

JaCoHSU commented 2 years ago

yes, its 18.04

python3 depthai_demo.py -gt cv does work. I guess I need to live with it for now. Thanks!

VanDavv commented 2 years ago

Hi @JaCoHSU ,

I installed Ubuntu 18.04 and I was able to make it work on this PR - https://github.com/luxonis/depthai/pull/571. The root cause of the issue is the QT library conflict between opencv-python and PyQt5, like mentioned in this issue on Qt forum.

To make the Qt GUI work on Ubuntu 18.04 please use the following commands

$ cd depthai  # repo root
$ git pull
$ git checkout ubuntu_1804_fix
$ export LD_LIBRARY_PATH="$HOME/.local/lib/python3.6/site-packages/PyQt5/Qt5/lib/
$ python3 depthai_demo.py

Will check if I can work around setting LD_LIBRARY_PATH, so that the script can load everything on its own.

Hi. I have the same problem under Ubuntu 20.04:

(oak-d) luis@ryzenLinux:/media/linuxDev/Oak-D/depthai(main)$ python3 depthai_demo.py 
Using depthai module from:  /media/linuxDev/envs/oak-d/lib/python3.8/site-packages/depthai.cpython-38-x86_64-linux-gnu.so
Depthai version installed:  2.13.3.0
QObject::moveToThread: Current thread (0x22d2060) is not the object's thread (0x21fbc70).
Cannot move to target thread (0x22d2060)

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/media/linuxDev/envs/oak-d/lib/python3.8/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.

Running with the CV GUI works fine (python3 depthai_demo.py -gt cv)

Luxonis-Brandon commented 2 years ago

Thanks for the report. Investigating.

JaCoHSU commented 2 years ago

Hey @VanDavv your suggestion worked for me. The gui opens :) Some core dumbs occur from time to time, but other than that it seems to work. thanks!

VanDavv commented 2 years ago

@JaCoHSU happy that it helped!

@piponazo could you try again with the latest main? I added the supervisor mode that should now set these flags automatically - #573

barney2074 commented 2 years ago

Hi @VanDavv

I am also having this problem- (I've got an 18.04 system for compatibility with other applications) It lloks like the fix has been removed from git ??- I get the following error

thanks

Andrew

alex-luxonis commented 2 years ago

Yeah, the branch was deleted as cleanup, it was merged in the meantime, in PR https://github.com/luxonis/depthai/pull/571. Could you post the logs (terminal prints) running with latest main?

barney2074 commented 2 years ago

Hi @alex-luxonis

Is this what you mean ??

I get the 'color' & 'depth' windows, just not the main GUI

VincentLombardi commented 2 years ago

I am having the exact same issue as you @barney2074. Fresh Ubuntu 22.04 VM on VMware workstation. Used the install requirements script. The camera connects just fine and the demo starts but I only get the color and depth windows. When I run natively on Windows 10 I get the full GUI just fine

Luxonis-Brandon commented 2 years ago

Oh yes sorry about the delay. So this means the QT GUI has failed. And when that happens, the demo automatically falls back to the OpenCV GUI.

We're in the process of re-writing the demo to use a web GUI instead. ETA probably 3-4 months. For now, if the QT GUI doesn't show up, the OpenCV GUI can be used with command line arguments to specify. There's also an experimental webGUI, but we're abandoning that for an alternate approach.

Thoughts?

Sorry again about the delay.

barney2074 commented 2 years ago

Hi Brandon

thanks for the response I've got it working (it is a little intermittent) on a 20.04 system, so I'm fine for now & will look forward to the webGUI

thanks

Andrew

Hey, just wondering what you changed to get the QT GUI working? I have a 22.04 system that I am wondering if that is the issue. The OpenCV GUI works alright (using CLI args. to change settings) but I would prefer the QT GUI. Thanks!

@Luxonis-Brandon Looking forward to testing out the webGUI!

barney2074 commented 2 years ago

Hi Vincent

I'm not sure- I started with a fresh 20.04.4 LTS (note- not 22.04) build

I don't know much about QT & if it is reliant on specific graphics drivers- but went through some real headaches with NVIDIA drivers, CUDA, cuDNN etc for other reasons

Andrew

VincentLombardi commented 2 years ago

Hi Andrew,

Awesome! Thanks for the info. I will give it a try.

Appreciate your help, Vincent
