corpus-viewer, word-cloud etc. not displaying text

[debojyoti31]

Describe the bug On Linux - Ubuntu 22.04 LTS. (with Xorg), installed orange using pip In Orange 3.32.0 while using text add-on corpus-viewer, word-cloud etc. not displaying any text.

To Reproduce Steps to reproduce the behavior:

1. select text add on
2. load a grimm-tales-selected.tab from documantation
3. connect to corpus-viewer

Expected behavior Display the text at the right side of corpus-viewer tab (which is not happening)

Orange version: 3.32.0

Text add-on version: 1.10.0

Screenshots

Operating system: Linux - Ubuntu 22.04 LTS. (with Xorg)

Additional context Add any other context about the problem here.

You are probably missing WebEngine components. Try running pip install PyQtWebEngine and see if it helps.

No, I already have it installed (Requirement already satisfied)

[ajdapretnar]

Can you run Orange with python -m Orange.canvas -l 4, try to reproduce the error and paste the log here?

Closed due to inactivity.

Hi @ajdapretnar ! Unfortunately, this affects me, too. Config: Arch Linux x86_64 ; Plasma 5.25.5 ; Kernel: 5.19.8-arch1-1 ; X11

Orange 3.32.0, installed via pip (running on its own environment, via pipenv) Text addon version 1.1.0

❯ pip install PyQtWebEngine
Requirement already satisfied: PyQtWebEngine in /home/aug/.local/share/virtualenvs/orange-KjjBmqEd/lib/python3.10/site-packages (5.15.5)
Requirement already satisfied: PyQt5>=5.15.4 in /home/aug/.local/share/virtualenvs/orange-KjjBmqEd/lib/python3.10/site-packages (from PyQtWebEngine) (5.15.6)

Requirement already satisfied: PyQtWebEngine-Qt5>=5.15.2 in /home/aug/.local/share/virtualenvs/orange-KjjBmqEd/lib/python3.10/site-packages (from PyQtWebEngine) (5.15.2)

Steps:

1. Run Orange with python -m Orange.canvas -l 4
2. Select the Corpus widget, connect its output to the Preprocess Text widget, and its output to Word Cloud
3. Double click on the Word Cloud widget to visualize its results
4. No visualization for Word Cloud

Please note this also happens when trying to read documentation for any widget, using F1 (it's been the case for many Orange versions now. Though only now I noticed that it happens for widgets other than "Help"/F1)

The log, when running with python -m Orange.canvas -l 4:

❯ python -m Orange.canvas -l 4

Please let me know if this is useful information, and if there's any additional info I can provide. Thanks!

[Albert5861]

This bug affects me too.

• Ubuntu 22.04 with Xorg
• Orange 3.34.1 installed with conda
• text add-on version 1.2 installed
• PyQtWebEngine installed

corpus viewer, word cloud etc. not displaying any text. It doesn't even show the help for me.

Every time I launch orange with the command "orange-canvas" and not with the command "python -m Orange.canvas" I get this error message: "QMainWindowLayout::tabPosition called with out-of-bounds value '0'"

Can anyone help me? Thank you

[PrimozGodec]

@ahfornitani and @Albert5861 thank you for the additional details. I also notice some weird behaviour on Ubuntu 22.04 while switching CI to newer Ubuntu (through our CI - automatic tests) https://github.com/biolab/orange3-text/pull/917. I will try to reproduce it to see what is wrong soon (I just need to prepare an Ubuntu VM).

[Albert5861]

@PrimozGodec and @ahfornitani thank you for your help. I want to add that the data I provided above relate to a machine installed a week ago from scratch to do this test. The machine is clean with the configuration I told you. I also have another Ubuntu 22.04.1 machine installed over six months ago (ubuntu 22.04.1 just came out) and there Orange data mining (installed with pip) works and doesn't have these problems. Whenever I install Ubuntu 22.04.1 on a new machine now it gives me these problems. The test machine I made for you to report this bug is a machine with an AMD Ryzen processor, but it gives the same error on an Intel Celeron (always with Ubuntu 22.04.1). Before writing to you I tried two other installations (Linux MInt 22.1 based on Ubuntu 22.04 and KUbuntu 22.04.1) and either it had the same error or it didn't start. Summary I tried 3 Ubuntu based distributions on two different hardware, even if I'm mainly interested in Ubuntu LTS 22.04 In my humble opinion one of the latest Ubuntu updates causes these errors. Thanks

[Albert5861]

@PrimozGodec @ahfornitani

I did one more test. I installed on a Virtualbox 6.1.40 virtual machine the same configuration:

• Ubuntu 22.04.1 with Xorg
• miniconda version 22.11.1 installed
• conda config --add channels conda-forge
• conda config --set channel_priority strict
• pyqt installed
• PyQtWebEngine installed
• Orange 3.34.1 (installed with conda)
• text-add-on version 1.2 installed

Here too I have the same errors: corpus viewer, word cloud etc. not displaying any text. It doesn't even show the help for me.

Thanks

[PrimozGodec]

@ales-erjavec, do you maybe know what the reason for this error is? I would like to know if you have seen something like this before I start installing Ubuntu somewhere to debug. It happens only on Ubuntu 22.04; it works fine on other OSs and at older Ubuntus.

[ales-erjavec]

Can you try running

QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu --no-sandbox" python -m Orange.canvas -l 4

[Albert5861]

@ales-erjavec @PrimozGodec @ahfornitani It works, thank you very much. With this workaround Orange finally displays the help, corpus viewer, word cloud, etc. :+1: What exactly does it depend on? Will this be fixed as a bug as well? Thanks

[ahfornitani]

Sorry if it counts as a duplicate / unnecessary comnent, but adding screenshots showing that it works for me, too:

Running with python -m Orange.canvas &>/dev/null:

Running with QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu --no-sandbox" python -m Orange.canvas -l 4

Thank you!

[PrimozGodec]

@ales-erjavec, thank you for the solution. Do you think it can be somehow included in WebView that users do not need to set environment variables?

[PrimozGodec]

@ales-erjavec, can those flags be somehow implemented in Orange so that users do not need to set them themselves?

[ales-erjavec]

No.

[PrimozGodec]

Ok then we can't do anything here. Closing
