Hi all, I have an issue installing and using the latest version of jgrapht with Python mode. I used to work with an older version tailored for Processing but that port is very limited and is missing most of the functions and classes of the original library. I have downloaded version 1.5.0 , put it …

I’ve never used jgrapht, but I did compile Processing 4 a while back – it seemed to work fine with Python mode.

I just installed Processing 4.0 alpha 2 following the instructions from the official repo but it seems Python mode doesn’t work correctly. Pressing the “play” button doesn’t launch anything: no canvas window, no working console. Can anyone confirm this ? Just to be sure I’m not the only one getting…

[image] solub: I went on installing JGraphT version 1.3.0 My link was about version [1.4.0]. Was there some other reason you’ve picked [1.3.0] instead? :thinking:

There was an open issue on Python mode on Processing 4, but I think eventually it will work (I hope so!)

I’ve just tested Processing 4.0 alpha 1 , which works fine with Python Mode. This issue must have crept in at alpha 2. As @villares has noted, the source of the problem has been identified and (self)-assigned to jdf to fix.

@GoToLoop – 1.4.0 is indeed to way to go ! I totally misread the description and thought the jump to Java 11 was from v1.4.0 included @tabreturn , @tabreturn – Thank you so much for all the clarifications ! Can’t wait to have Python mode running on Processing 4. All the best to everyone.

@villares @tabreturn : Do you know if the latest release of Processing 4 ( alpha 3 ) works with Python mode ?

Alpha 3 isn’t working with Python Mode :frowning_face: I get an error message that reads: WARNING: An illegal reflective access operation has occurred * tested on Linux

Thank you so much for the quick testing ! I also had an error last time I checked, a bit disappointing.
