Blank ClusterView and SimilarityView

[AntonioST]

Hi,

I got some problem to start with a template-gui on my kilosort result. The ClusterView and SimilarityView didn't show anything. No mater how long I wait, it didn't change the blank content. If I tried to close the window, a timeout dialog pop up.

Here are the part of packages installed in my conda environment.

# Name                    Version                   Build  Channel

phy                       2.0a1                    pypi_0    pypi
phylib                    2.4.1                    pypi_0    pypi

I guess it is something relate to the QtWebEngine which js wasn't run.

Thanks

I have the same problem. Have you found a solution to this?

Hi @AliyaAbl

I don't the real reason why qtwebengine is unable to show html content, but this command works on my linux computer env QTWEBENGINE_CHROMIUM_FLAGS="--single-process" phy template-gui .../params.py.

I just find out this way this morning. I tried a simple QWebEngineView example with conda Qt (pyqtwebengine-qt 5.15.2 from conda pypi chanel), and my OS Qt (python-pyqt5-webengine-5.15.5-4 from archlinux). I have no such issue with my OS Qt.

I have the same problem and this @AntonioST solution works.

had the same issue, and solution from @AntonioST works for me too, thanks!

@rossant could you add this to the Troubleshoot section?

[KBillel]

Worked for me as well thank you !

@AntonioST You are a lifesaver! Thank you.

hey i am a bit inexperienced but where should i write the env QTWEBENGINE_CHROMIUM_FLAGS="--single-process" phy template-gui .../params.py. command exactly?

[rory-bedford]

Hey @Coglet00, I'm guessing you're on linux?

In bash, you can define an environment variable for the execution of a specific command by putting it before the command. So in this case, we're setting QTWEBENGINE_CHROMIUM_FLAGS to "--single-process", then just running the usual command 'phy template-gui params.py'. The env bit at the start shouldn't matter much (it just runs the command in a clean environment). So in your terminal, navigate to the phy data directory, make sure it has params.py in your current directory, then run the command (don't actually put the .../ at the start).

[Coglet00]

thanks for the reply!! i already have a separate environment for phy2 and i always open phy in the environment.

i always navigate to the params.py folder and write env QTWEBENGINE_CHROMIUM_FLAGS="--single-process" and then phy template-gui params.py

surprisingly my cluster view are still empty but when i drag and hold my mouse i get the output . but it goes away when i leave the mouse

[rory-bedford]

Just to clarify is that on the same line? So your full command should be:

QTWEBENGINE_CHROMIUM_FLAGS="--single-process" phy template-gui params.py

If you run them on different lines the environment variable QTWEBENGINE_CHROMIUM_FLAGS won't get saved for when you run the next command.

Sorry if this is pedantic just checking though!

Also worth trying without env in front - I don't think it should be used here (see https://stackoverflow.com/questions/13998075/setting-environment-variable-for-one-program-call-in-bash-using-env)
