GAMSpy error

[opt123]

Hi there,

Vey excited about gamspy, since it helps us connect our Python code with our GAMS code!

I find the debugging part a little bit tricky but I guess this will get easier with some experience.

I have typed all the equations of my model in gamspy but I get the error that you find attached.

I have printed the sets that I use as indices and they seem to be alright. Do you have any idea how this can be resolved?

Thank you for your time.

I fear your screen shot is not enough to point you to the issue. Please share the entire Python script (or make a minimal example) so one can reproduce. If you are a licensed user and can't share the script here in the forum, you might want to consider to email support@gams.com with something that let them reproduce the issue.
