I actually think I do this. Purpose of normalize_and_flat_config is just to take hparams DictConfig with possibly nested structure and flatten it to dict with direct key value dict. For instance:
{ 'model' : { 'class' : Resnet, 'input_size' : [112, 112, 3] } }is simplified to
{ 'model.class' : Resnet, 'model.input_size' : [112, 112, 3] }so in my case normalize_and_flat_config(hparams) is actually your overrides . And as you suggest I tried to remove Task.connect_configuration and just keep the Task.connect . But thanks to you I realized one thing: I use hparams further in the code, not normalize_and_flat_config(hparams) . So, viewing it in types, I am using DictConfig and not dict and that might be the problem. Wdyt?
