What Does "No module named 'gurobipy' mean"?

Awaiting user input

I will start by sayin I am VERY new to Gurobi but I have been using Gurobi successfully and, last night, began receiving the following message when I attempted to create a new model:

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Input In [1], in <cell line: 1>()
----> 1 import gurobipy as gp
      2 from gurobipy import GRB

ModuleNotFoundError: No module named 'gurobipy'

It looks likes Gurobi isn't installed, correct? If so, it was yesterday morning when I ran another model.

  There could be many reasons for this behaviour. One of the most common is the fact that Gurobi may be installed in a different (conda) environment than the one you are using it.

  Could you please share some more details about the Python / Gurobi version you are using?

  Best regards
