'''Invokeai configuration system.
Arguments and fields are taken from the pydantic definition of the
model. Defaults can be set by creating a yaml configuration file that
has top-level keys corresponding to an invocation name, a command, or
"globals" for global values such as `xformers_enabled`. Currently
graphs cannot be configured this way, but their constituents can be.
[file: invokeai.yaml]
globals:
nsfw_checker: False
max_loaded_models: 5
txt2img:
steps: 20
scheduler: k_heun
width: 768
img2img:
width: 1024
height: 1024
The default name of the configuration file is `invokeai.yaml`, located
in INVOKEAI_ROOT. You can use any OmegaConf dictionary by passing it
to the config object at initialization time:
omegaconf = OmegaConf.load('/tmp/init.yaml')
conf = InvokeAIAppConfig(conf=omegaconf)
By default, InvokeAIAppConfig will parse the contents of argv at
initialization time. You may pass a list of strings in the optional
`argv` argument to use instead of the system argv:
conf = InvokeAIAppConfig(arg=['--xformers_enabled'])
It is also possible to set a value at initialization time. This value
has highest priority.
conf = InvokeAIAppConfig(xformers_enabled=True)
Any setting can be overwritten by setting an environment variable of
form: "INVOKEAI_<command>_<value>", as in:
export INVOKEAI_txt2img_steps=30
Order of precedence (from highest):
1) initialization options
2) command line options
3) environment variable options
4) config file options
5) pydantic defaults
Typical usage:
from invokeai.app.services.config import InvokeAIAppConfig
from invokeai.invocations.generate import TextToImageInvocation
# get global configuration and print its nsfw_checker value
conf = InvokeAIAppConfig()
print(conf.nsfw_checker)
# get the text2image invocation and print its step value
text2image = TextToImageInvocation()
print(text2image.steps)
Computed properties:
The InvokeAIAppConfig object has a series of properties that
resolve paths relative to the runtime root directory. They each return
a Path object:
root_path - path to InvokeAI root
output_path - path to default outputs directory
model_conf_path - path to models.yaml
conf - alias for the above
embedding_path - path to the embeddings directory
lora_path - path to the LoRA directory
In most cases, you will want to create a single InvokeAIAppConfig
object for the entire application. The get_invokeai_config() function
does this:
config = get_invokeai_config()
print(config.root)
