Unable to run cameo design API

[SiYeon-Ju]

Hi, I tried to run a example of design API (https://cameo.bio/08-high-level-API.html).
But, i had no results. What should I do?

############################################
[ Python Ver 3.7.14 in Google Colab]
!pip install cameo
!pip install cobra==0.17.0

import cameo
import cobra
from cameo import api
from cameo.parallel import MultiprocessingView

mp_view = MultiprocessingView()
api.design.options.max_pathway_predictions = 4
api.design.options.heuristic_optimization_timeout = 30
report = api.design(product = 'vanillin', view = mp_view)
###############################################

Not an expert on the high level design API, but it seems like your computer hit the timeout.

You can try either changing the timeout (you set it to 30 as in the documentation) or the linear programming solver. Different underlying linear programming solvers need more or less time to run the simulations, and, of course, it also depends on your hardware.
