I was able to get the code to work without the need for the from hydra_zen import store, zen, builds, make_config
from game_library import inventory, Character

player_store = store(group="player")
player_store(CharConf, name="base")
# Task function
def task_function(player: Character):
print(player)
with open("player_log.txt", "a") as f:
f.write("Game session log:\n")
f.write(f"Player: {player}\n")
return player

Still can't get from hydra_zen import store, zen, builds, make_config

I'll take a look at this later today in more detail. But at first glance of your initial post I'm a bit confused, In the last comment, you have |

Yeah I think you got it there. You don't have to configure your launch function, although this is an interesting approach to automatically execute your function upon instantiation of the configuration object. Here are two alternatives:
from hydra_zen import builds, make_config, launch, store, zen
# Inventory config
starter_gear = builds(inventory, gold=10, weapon="stick", costume="tunic")
# Task function
def task_function(player: Character):
print(player.inventory)
with open("player_log.txt", "a") as f:
f.write("Game session log:\n")
f.write(f"Player: {player}\n")
return player
# Use auto-config feature of store
store(
Character,
inventory=starter_gear,
populate_full_signature=True,
group="player",
name="base",
)
# Make top-level config to use in `launch` (no need for store)
Config1 = make_config(
hydra_defaults=["_self_", {"player": "base"}],
player=None,
)
store.add_to_hydra_store()
job = launch(
Config1,
zen(task_function),
overrides=["player.name=frodo"],
version_base="1.1",
)
# not using store, just making the configuration
CharConf = builds(
Character,
inventory=starter_gear,
populate_full_signature=True,
)
# Create top-level config
Config2 = make_config(player=CharConf)
job = launch(
Config2,
zen(task_function),
overrides=["player.name=frodo"],
version_base="1.1",
) |

I recommend reading the reference docs: https://mit-ll-responsible-ai.github.io/hydra-zen/generated/hydra_zen.ZenStore.html#hydra_zen.ZenStore In the Examples section, you'll see an explanation of the auto-config and the decorator behavior. We generally try to partition our docs so that the How-To are focused on how to accomplish specific tasks -- without taking detours to explain the specifics/mechanics of individual functions -- and reserve the Reference docs for deep-diving the details of each component of hydra-zen's API. |

Gotcha, yeah that makes sense. Have been starting to rely on the reference docs more, guess I just didn't scroll far enough on the |

Hey all,
Since there are multiple ways to do things, today I wanted to see if could alter the version of
my_app.pyfrom the "Design a Hierarchical Interface for an Application" tutorial. There are two alterations that I wanted to make but at the moment I have been unsuccessful with both.launch()instead of using the CLI@storedecorator. I got nowhere real fast with this. I think this stems from not really knowing why the tutorials switched to using this decorator in the first place. In other words, what does using this decorator afford us that wasn't previously doable? I wanted write things without the decorator for a couple reasonsBut the decorator obfuscates this understanding; the decorator does some config work that I don't follow, and hence can't get around. From the error messages I have been seeing, I suspect that it has to do with how different things are given default values.
Not a top concern for me at the moment, but the tutorial introduces the use of
hydra_zen.make_custom_builds_fn()without much explanation. The one thing I was able to successfully do was to usehydra_zen.builds()instead.Revisiting using
launch(): I was never able to run the code as stated in the tutorial. For one, the tutorial refers toConfigwhich is never defined withinmy_app.py. Here is my attempt to implementlaunch()If I run this I get the following error message:
It looks to me that I have an issue regarding how to set default values. I tried a few version of the code (you can tell from some code that is commented out, for example), but no luck.
Thanks,
Francisco
