Failed to create new environment in gurobipy

In order to suppress unnecessary console logs, I tried to follow the instruction in https://support.gurobi.com/hc/en-us/articles/360044784552-How-do-I-suppress-all-console-output-from-Gurobi to create a new environment in gurobipy and create a new model within this environment.

However, for some reason this always fails with "Failed to create new environment" in the line:

with gp.Model(env=env) as m:

But if I just run it without attaching the environment (by using the default environment), i.e.:

m = gp.Model("test")

Then it has no problem running at all - just that it will produce lots of unnecessary output because I am running many models sequentially.

Anyone has idea why this problem arises?

I have an academic license.

Hi Zhipeng,

When you use

gp.Model("test")

Gurobi will be using a default environment.

you are specifying a (probably non-default) environment.

Can you provide the code where you are creating env? (Please replace any license details in this code with junk if applicable).
