Hi,

First of all, thanks for your module it is very helpful.

I managed to make it work a few months ago but when i tried to install it on a new computer this week, i got this error :

/tmp/build/80754af9/wxpython_1547931003892/work/ext/wxWidgets/src/unix/threadpsx.cpp(1810): assert "wxThread::IsMain()" failed in OnExit(): only main thread can be here [in thread 7fe42f4e6740] /tmp/build/80754af9/wxpython_1547931003892/work/ext/wxWidgets/src/common/socket.cpp(767): assert "wxIsMainThread()" failed in IsInitialized(): unsafe to call from other threads [in thread 7fe42f4e6740]

It comes up when i try to call the function : "slmpy.SLMdisplay()"

I know it is linked to multithreading but i didn't manage to solve the issue.

If you have an idea...

Thanks !

PS : it works fine in command line. I just cant manage to make you example work inside a classic python script. I know it is linked to my lack of knowledge in multithreading ...

Hi,

This error is "normal", cf my reply to this issue It will be displayed when you exit the program, your error is elsewhere, but I cannot help without seeing the code. Please provide a minimal reproducable example for this issue.
