The availablity for from_pyscipopt() function

[jp18813100494]

Recently, I create a new model for VRPTW problem based on Pyscipopt. Then I want to transform the Pyscipopt model to Ecole model, thus obtaining the structured observation data including column, node, edge features. However, one mistake happens when I utilized ecole.scip.Model.from_pyscipopt() . I wanna ask is the from_pyscipopt() function available now? Or I made some mistakes when I operate? Can you provide an example for from_pyscipopt?

Hi @jp18813100494,

Yes, ecole.scip.Model.from_pyscipopt should be working (not all cases have been tested).

However, one mistake happens when I utilized ecole.scip.Model.from_pyscipopt()

Could you provide more information of the nature of your error, such as the error message.

Can you provide an example for from_pyscipopt?

import pyscipopt
import ecole

model_pysciopt = pyscipopt.Model()
# Keep on using the pyscipopt functions
...

# Data between the two functions are shared (same memory)
model_ecole = ecole.scip.Model.from_pyscipopt(model_pysciopt)
# Keep on using the ecole functions
...
