CFclient 2023.11 not starting due to QT6 mismatch #690

Open matejkarasek opened 9 months ago

matejkarasek commented 9 months ago

Hi, I cannot get to run the latest release (2023.11) on Win 11 with Python 3.11.4 installed via pip. 2023.6 works fine. Didn't dig deeper into it, but seems to be related to switching to Qt6?

Hi! hmmm... that's odd. It sounds like the same issue that people see in the VM... https://github.com/bitcraze/crazyflie-clients-python/issues/689

I'm running it on windows 11 as well with python 3.10, and it worked for me. Is it perhaps something that is missing on this list I wonder? https://doc.qt.io/qt-6/linux-requirements.html, but I can't find the windows equivalent

knmcguire commented 9 months ago

@matejkarasek which version of pyqt6 was installed on your machine?

matejkarasek commented 9 months ago

I believe it is 6.6.0

Hmm interesting. I have 6.5.2. Let me see if I can update it

knmcguire commented 9 months ago

I've just upgraded it to 6.6.1 and no issues there.. the search continues!

matejkarasek commented 9 months ago

So I found a fix. I uninstalled cfclient as well as anything Qt6 related. After that, pip install cfclient and all seems to work!

The problem must have been different versions of PyQt6 and PyQt6-Qt6:

Before

PyQt6               6.6.0
PyQt6-Qt6           6.6.1
PyQt6-sip           13.6.0

After

PyQt6               6.6.1
PyQt6-Qt6           6.6.1
PyQt6-sip           13.6.0
knmcguire commented 9 months ago

Ah good one! Perhaps a bit tricky if already a QT 6 version was installed on the computer... would be handy to not have that happen. We should perhaps put in a check on startup that can detect this mismatch and give some kind of error (like reinstalling QT6)

knmcguire commented 9 months ago

So I've tried it on a clean venv environment, and it opens without issues, so this is an problem for anybody that have installed the cfclient through the development branch first a while ago and then updates it.

So in that sense this fix should be:

pip3 uninstall PyQt6 PyQt6-Qt6 PyQt6-sip cfclient cflib
pip3 install cfclient
knmcguire commented 9 months ago

Same thing with the bitcraze VM, in a clean install this issue will not happen. I'd still like to be able to handle issues like this though... either as a startup warning or indicating in documentation... so let's keep this issue open for now.

zsh: abort cfclient

knmcguire commented 9 months ago

Hi! You don't have the same error as @matejkarasek had:

    from PyQt6 import QtWidgets
ImportError: DLL load failed while importing QtCore: The specified procedure could not be found.

Yours is 

qt.qpa.plugin: Could not find the Qt platform plugin "cocoa" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem

@faezehmhmdi Could you start a thread in discussions for this so we can first determine if it's an actual bug in the cfclient or just a missing package? https://discussions.bitcraze.io/
