03/27/2023, 1:58 PMHi, yes I have. From what I understand parameters versioning is made possible because the git info in Kedro Viz maps to the config specified in the source code when pipeline ran.
However, say I override one of the parameters through CLI, is there any way to recover the resulting config? I was expecting "Run Command" in Kedro Viz to be updated accordingly but my testing showed it isn't (is this an issue on my end?).

kedro run --params=some_param:2.5kedro rund

03/27/2023, 3:54 PMWhat I would say is that if you want to save your CLI parameters you could write your own hook the same way we do

03/27/2023, 4:13 PMAmazing 👍 thanks a lot
I've exposed the extra params by tweaking the kedro viz code
I think this should be enough for my use case for now. CLI param overrides can be reproduced by rerunning the pipeline with same git commit, and with the same CLI params
