QT error while running on Ubuntu 20.04

[sunilvbharadwaj]

I am getting an error like this:

"QSocketNotifier: Can only be used with threads started with QThread QObject::startTimer: Timers can only be used with threads started with `QThread"

when I run main.py file.

Anyone else running into this issue?

Hello, sunilvbharadwaj. I tried running BARAM on Ubuntu 20.04 but could not reproduce the problem. Following is my system information.

jake@vmlinux:~/workspace/baram$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04.5 LTS"
jake@vmlinux:~/workspace/baram$

Could you send me the whole console output starting from activating python virtual environment like following?

jake@vmlinux:~/workspace/baram$ source venv/bin/activate
(venv) jake@vmlinux:~/workspace/baram$ python main.py

BARAM Running...

(venv) jake@vmlinux:~/workspace/baram$ deactivate
jake@vmlinux:~/workspace/baram$

(base) abb@server2:~$ conda deactivate abb@server2:~$ cd Software/baram abb@server2:~/Software/baram$ source ~/venv/bin/activate (venv) abb@server2:~/Software/baram$ python main.py QSocketNotifier: Can only be used with threads started with QThread QObject::startTimer: Timers can only be used with threads started with QThread ``

Is this what you are looking for? And thanks for replying.

[jiban]

Yes, But it seems that there was no back trace message from python. Did BARAM go running after the message or it showed more messages and stopped?

[sunilvbharadwaj]

Hi Jiban,

It just showed me this message. Didn't open the application.

[jiban]

The message makes me suspect that qasync python module is not working well. qasync module provides asynchronous function based on QT Threads. Could you give me the package list for me to see if virtual environment is setup correctly? You can get the list with pip list command in python virtual environment.

Hi Jiban, I upgraded the pip too.

Let me try with a different installation of Ubuntu or Rocky linux. Then I can rule out this being a Baram error. I will keep this ticket open till then. Thanks.

[jiban]

Sure, I will be waiting. Thank you.

Dear sunilvbharadwaj, I could see PyQt and PySide2 as well as PySide6 in your list. It's different from the virtual environment where BARAM is supposed to run in. Only the packages in requirements.txt and their dependency are expected in the venv(virtual environment for BARAM). Could you try it in clean environment?
