Typical usage:

|
|
from invokeai.backend.model_manager import ModelConfigFactory
|
|
raw = dict(path='models/sd-1/main/foo.ckpt',
|
|
name='foo',

type='main',
|
|
config='configs/stable-diffusion/v1-inference.yaml',

variant='normal',

|
format='checkpoint'

|
)
|
|
config = ModelConfigFactory.make_config(raw)
|
|
print(config.name)
|
|
|
|
Validation errors will raise an InvalidModelConfigException error.
