Hi Daniele,
Thank you for your report and for trying out Harvester!
One question: Which version of VisPy did you try to use with Harvester GUI? I think I have not specified VisPy version so you would get the latest version. However, I have just noticed they have already started to release on the 0.6 line that I had never tried before. Yeah, you might have confirmed Harvester GUI failed to work with a 0.5 but it's okay, we would nail it soon or later.
Best regards,
Kazunari
Hi Kazunari,
thank you for the response.
I tryed
- vispy 0.5.3, black screen
- vispy 0.4.0, TypeError: message_handler() takes 2 positional arguments but 3 were given
- vispy 0.6.2, black screen
In my current setup I have installed
- harvesters 0.2.13
- harvesters-gui 0.2.5
- pyqt 5.13.2
If you have a working setup can you please tell me which version are currently working? I'm willing to help updating the code if necessary.
Thank you,
Daniele
Sorry for the delay. I have just confirmed the issue and the root cause is coming from the change made on Harvester version 0.2.13. I will fix the issue later. Thank you for your patience.
Sorry having kept you waiting for such long. I have just released version 0.3 that fixes the issue. Please let me know if it does not work for you. /Kazunari
