ignore a field when saving omagaconf

[nghorbani]

I wonder if it is possible to leave out a certain field when saving yaml configuration to a file?

Hi @nghorbani,

You can try deleting the field from the config before saving it.
For example:

>>> cfg = OmegaConf.create({"a": 1, "b": 2, "c": 3})  # create a new config
>>> print(cfg)
{'a': 1, 'b': 2, 'c': 3}
>>> from copy import deepcopy
>>> cfg2 = deepcopy(cfg)  # make a copy of the config
>>> del cfg2["c"]  # delete a field from the copy
>>> print(cfg2)
{'a': 1, 'b': 2}
>>> OmegaConf.to_yaml(cfg2)
'a: 1\nb: 2\n'
>>> print(cfg)  # the original config still has the "c" field
{'a': 1, 'b': 2, 'c': 3}
