Pyomo模块报错：‘module 'pyomo' has no attribute 'AbstractModel'’求助

Hey there, let's fix this Pyomo issue you're running into!

The error pops up because AbstractModel isn't directly part of the top-level pyomo module—it's housed in the pyomo.environ submodule, which holds most of Pyomo's core modeling tools.

Here are two simple, effective fixes:

• Option 1: Import the environ submodule with an alias (recommended)
  This is the standard way to work with Pyomo, as it gives you access to all core components without cluttering your code's namespace:

  import pyomo.environ as pmo
  absmd = pmo.AbstractModel()
  

• Option 2: Import AbstractModel directly
  If you only need this specific class for your task, you can import it directly:

  from pyomo.environ import AbstractModel
  absmd = AbstractModel()
  

Either approach will resolve the AttributeError and let you create your abstract model smoothly.
