Error #91

Note that Sympify caused a similar error in the last version when I tried to code comparison operators. It evaluated parts of some statements. |
Try with ‘==‘ instead?
Thanks for the feedback though, that's something we should recognize early and give a clearer error message.

By the way the operator is >= I don't know why this editor removed the >. I tried removing OR and keeping >= and the run completes successfully, but if >= and or are in the operator list it crashes. Note the error at the end: TypeError: '>=' not supported between instances of 'GreaterThan' and 'GreaterThan' |
On the other hand, if settings are c,r,5,5,3,120,1000 The session will run with no problem. You may ask why I modified the generations to be able to reach 1000; well according to my experience this is important to reach better fitness values, and no, the result would not be overfitted. |
Ok, let me take a look. Can you send the exact command-line prompt you're using? like |
This is the command line prompt: sudo nice -1 python karoo-gp.py My problems are:
I hope this helps If you need me to do specific tests, I would be more than happy |
Hello,
I got a consistent error with one of my setups. The data is error free and works with other operator setups but not this one:
+,2
-,2
