Tamer incompatible with UP v0.6?

[jrenoux]

Hi,

I just updated the UP to 0.6, with Tamer installed, and the following code is now breaking:

import unified_planning as up
from unified_planning.shortcuts import *

type_family = UserType("type_family")

With the following error:

Traceback (most recent call last):
  File "<dir>test_v_6.py", line 4, in <module>
    type_family = UserType("type_family")
  File "<dir>/python3.10/site-packages/unified_planning/shortcuts.py", line 496, in UserType
    return get_environment().type_manager.UserType(name, father)

Reverting to UP 0.5 removes the problem.

Did you also upgrade up-tamer?

[jrenoux]

Yes, I am on up-tamer 0.3.1 from Pypi

[alvalentini]

You should install the engines trough the unified-planning:

pip install unified-planning[tamer]==0.6.0

Ok, turned out I was using the wrong syntax in Poetry to manage my packages as extras. Thanks for the help!
