override config key at command line

[lstrgar]

Hi. I'm surprised to see this does not work:

main.yaml

defaults:
  - _self_
  - optim: adam

optim/adam.yaml

lr: 0.001
betas: [0.9, 0.999]

python run.py optim.lr=0.01

When I run this above, the original value of 0.001 is still being set. What am I missing?

Not sure. I'm not able to reproduce the behavior you're seeing; when I run python run.py optim.lr=0.01 on my machine, I get {'optim': {'lr': 0.01, 'betas': [0.9, 0.999]}}.

Could you paste the output of the following command?

python run.py optim.lr=0.01 --info

You are right. I had a bug where loading a model checkpoint was overwriting values read from the config.
