I'm using Hydra 1.0.6

If I edit directly the OmegaConf in the UI than the port changes correctly

This will only work if you change the Hydra/allow_omegaconf_edit to True in the UI. Did you?

Ohh so you are saying you can store it properly, but only editing in the UI is limited ? (Maybe this is just a UI thing)

Yes I think it's only related to the UI. Do you think It can be fixed somehow? It would be the easiest way to launch new experiments with a different configuration

Actually I had the same issue even with that value set to False

For example, could you test if this one works:

Also, if I want to modify another parameter, e.g. ui.height I have this problem:

Yep I changed it

Thank you!!

Hi AgitatedDove14 , I noticed that in the Hydra parameters section it is not possible to add as parameters keys string with dots: .(dot) $(dollar) and space are not allowed in parameter key. However, it's very useful to add parameters with the dot to change something in a sub-configuration as, for example, training.max_epochs=10 . Do you think it's possible to allow this?

` # ClearML - Hydra Example

from clearml import Task

from dataclasses import dataclass

import hydra
from hydra.core.config_store import ConfigStore
from omegaconf import OmegaConf

@dataclass
class MySQLConfig:
host: str = "localhost"
port: int = 3306

cs = ConfigStore.instance()

Registering the Config class with the name 'config'.

cs.store(name="config", node=MySQLConfig)

@hydra.main(config_name="config")
def my_app(cfg: MySQLConfig) -> None:
# type (DictConfig) -> None
task = Task.init(project_name="examples", task_name="hydra configuration")
logger = task.get_logger()
logger.report_text("You can view your full hydra configuration under Configuration tab in the UI")
print(OmegaConf.to_yaml(cfg))

if cfg.port == 80:
    print("Is this a webserver?!")

if name == "main":
my_app() `

I'm using ClearML 0.17.5

Yep I changed it

This means it will totally ignore the overrides and just take the OmegaConf, this is by design. You either use the overrides, or you configure the OmegaConf. LovelyHamster1 Does that make sense ?

However, If I edit directly the OmegaConf in the UI than the port changes correctly. I'd still prefer to override the Args so I can change entire sub-configuration e.g. ['dataset=cifar'] to ['dataset=imagenet'] instead of having to change all the parameters inside the OmegaConf

Ok now I noticed that If I change the value of the port inside the Hydra parameters section ( not the overrides) It does actually change also in the experiment. The overrides doesn't seem to be working

LovelyHamster1 verified, this is a UI bug with old limitation enforced.
I will make sure they know about it, it should be fixed for the upcoming release 🙂

Hi LovelyHamster1
Could you think of a toy code that reproduces this issue ?

Hi AgitatedDove14 , sorry for the late reply. Btw, I tried with the latest RC and the issue is still there. So if I clone an experiment, modify an overrides params eg ['training.max_epochs=10'] my experiment run the old configuration. Therefore it seems that it doesn't change the OmegaConf configuration.

Hi LovelyHamster1
As you noted, passing overrides in Args/overrides , for example ['training.max_epochs=1000']
should work when running with the agent.

Could you verify with the latest RC, there was a fix to support the latest hydra version
pip install clearml==0.17.5rc5

Hi AgitatedDove14 , you can try with this toy example. If i run the task with python example.py ui.width=2048 the task will run correctly and print Title=My app, size=2048x768 pixels . However, in the UI I'm not allowed to change the ui.width in the Hydra parameters section: the 'Save' button is frozen

Hi LovelyHamster1
You mean when as a section name or a variable?
Could you change this example to include a variable that breaks the support ?
https://github.com/allegroai/clearml/blob/master/examples/frameworks/hydra/hydra_example.py

` from clearml import Task

from dataclasses import dataclass

import hydra
from hydra.core.config_store import ConfigStore
from omegaconf import OmegaConf

@dataclass
class MySQLConfig:
host: str = "localhost"
port: int = 3306

@dataclass
class UserInterface:
title: str = "My app"
width: int = 1024
height: int = 768

@dataclass
class MyConfig:
db: MySQLConfig = MySQLConfig()
ui: UserInterface = UserInterface()

cs = ConfigStore.instance()
cs.store(name="config", node=MyConfig)

@hydra.main(config_name="config")
def my_app(cfg: MyConfig) -> None:
task = Task.init(project_name="examples", task_name="hydra configuration")
logger = task.get_logger()
logger.report_text("You can view your full hydra configuration under Configuration tab in the UI")
print(f"Title={cfg.ui.title}, size={cfg.ui.width}x{cfg.ui.height} pixels")

if name == "main":
my_app() `

Do you think It can be fixed somehow? It would be the easiest way to launch new experiments with a different configuration

Let me check, it might be it.

It would be the easiest way to launch new experiments with a different configuration

Definitely

I created this toy example so you don't need any external conf files. Btw if I first launch the task as python example.py port=80 than the task will print the message "Is this a webserver" correctly. If then in the UI I clone the same task, overrides the port with ['port=43'] , for example, and run the experiment, I will still get the message "Is this a webserver" so the port didn't change

Hmm. What's the Hydra version you have?
