Gurobi-通过状态码获取状态消息？

Question

Is there a way to get the status message using a status code? For error codes I can easily get the message by catching the exception and accessing its .message attribute, however for statuses I only get the code from:

model.status

It seems like the messages are stored in the Gurobi library since it prints out a message when something happens, for example encountering an infeasible model, but I don't see a way of accessing the message itself, ie storing it in a variable.

There is no API function to retrieve the internal status message, but it's fairly simple to set up a message dict yourself for that purpose. Assuming that you have imported GRB , one could do:

>>> # TODO add more status codes here...
>>> msgdict = {GRB.OPTIMAL : 'Optimal', GRB.INFEASIBLE : 'Infeasible model'}
>>> model.optimize()
>>> print msgdict[m.status]
Optimal
