Exception originated from within Sacred. KeyError: 'Invalid key "DogmaticDict.__setitem__". Config-keys cannot contain "." or start with "$"'

Hey,

I have some issues with the originated from within Sacred when i debug my code.

ex = sacred.Experiment('Global (train)', ingredients=[data_ingredient, model_ingredient],interactive=True)
SETTINGS.CAPTURE_MODE = 'sys'
ex.captured_out_filter = apply_backspaces_and_linefeeds
@ex.automain
def main(epochs, cpu, cudnn_flag, temp_dir, seed, no_bias_decay):
       '...'

When i debug until the line of @ex.automain, the error was raised as follows.

Exception originated from within Sacred.
Traceback (most recent calls):
File "/root/anaconda3/lib/python3.10/site-packages/sacred/config/utils.py", line 42, in assert_is_valid_key
raise KeyError(
KeyError: 'Invalid key "DogmaticDict.setitem". Config-keys cannot contain "." or start with "$"'

I find the error happen in line 42, in assert_is_valid_key

def assert_is_valid_key(key):
        if SETTINGS.CONFIG.ENFORCE_KEYS_MONGO_COMPATIBLE and (
                isinstance(key, str) and ("." in key or key[0] == "$")
            ):
                raise KeyError(
                    'Invalid key "{}". Config-keys cannot '
                    'contain "." or start with "$"'.format(key)
                )

And the key is defined as:

def normalize_or_die(obj):
    if isinstance(obj, dict):
        res = dict()
        for key, value in obj.items():
            assert_is_valid_key(key)
            res[key] = normalize_or_die(value)
        return res
    elif isinstance(obj, (list, tuple)):
        return list([normalize_or_die(value) for value in obj])
    return normalize_numpy(obj)

But i cannot find the definition of obj. And I cannot find any solution online.

I would be grateful for some help!

Best,

Hey! What does your config look like?
