In my Gurobi log I see information that is not obviously available through the Python API:

Reading time = 153.94 seconds

Presolve removed 52 rows and 53 columns (presolve time = 15s) ...

How do I capture this information from the API? The only way I can think to capture what happens in presolve is to seperately presolve() and then optimize() and record the clock time. Is there a better way?

  Hi,

  I am sorry, we don't offer a attribute or an API method to query the reading time or the presolve time. The only way of getting these number is to parse the log file.

  Best regards,
