Sorry, thought I was putting those previous messages in a single thread. Fixed New question, new thread: Is there a way to set a parameter in a node? If my first node calls a function

date()

that simply gets the datetime date, can I assign that date to a parameter?

You will probably want to set it as parameters instead of changing your parameters in a pipeline - this makes your pipeline very hard to debug. As your previous question is asking about how to output the parameters, imagine if your parameters later actually get assigned a different value.

Oh that is very fun, I'll have to try that out. Thanks!

@Nok Lam Chan is right - after the next release (or if you use the

main

branch of the source code), you would be able to set custom resolvers through

CONFIG_LOADER_ARGS

in your

settings.py

like this :

def mydate():
    return whatever

CONFIG_LOADER_ARGS = {
    "custom_resolvers": {
        "date_resolver": lambda: mydate(),
    }
}

And then in your

parameters.yml

my_date: "${date_resolver:}"

--- Right now you can also do in your

settings.py

def mydate():
    return whatever

from omegaconf import OmegaConf
if not OmegaConf.has_resolver("date_resolver"):
    OmegaConf.register_new_resolver("date_resolver, lamda: mydate())
