"""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 a top-level key of "InvokeAI" and subheadings for each of the
categories returned by `invokeai --help`. The file looks like this:
[file: invokeai.yaml]
InvokeAI:
Paths:
root: /home/lstein/invokeai-main
conf_path: configs/models.yaml
legacy_conf_dir: configs/stable-diffusion
outdir: outputs
autoimport_dir: null
Models:
model: stable-diffusion-1.5
embeddings: true
Memory/Performance:
xformers_enabled: false
sequential_guidance: false
precision: float16
max_cache_size: 6
max_vram_cache_size: 0.5
always_use_cpu: false
free_gpu_mem: false
Features:
esrgan: true
patchmatch: true
internet_available: true
log_tokenization: false
Web Server:
host: 127.0.0.1
port: 8081
allow_origins: []
allow_credentials: true
allow_methods:
- '*'
allow_headers:
- '*'
The default name of the configuration file is `invokeai.yaml`, located
in INVOKEAI_ROOT. You can replace supersede this by providing any
OmegaConf dictionary object initialization time:
omegaconf = OmegaConf.load('/tmp/init.yaml')
conf = InvokeAIAppConfig()
conf.parse_args(conf=omegaconf)
InvokeAIAppConfig.parse_args() will parse the contents of `sys.argv`
at initialization time. You may pass a list of strings in the optional
`argv` argument to use instead of the system argv:
conf.parse_args(argv=['--xformers_enabled'])
It is also possible to set a value at initialization time. However, if
you call parse_args() it may be overwritten.
conf = InvokeAIAppConfig(xformers_enabled=True)
conf.parse_args(argv=['--no-xformers'])
conf.xformers_enabled
# False
To avoid this, use `get_config()` to retrieve the application-wide
configuration object. This will retain any properties set at object
creation time:
conf = InvokeAIAppConfig.get_config(xformers_enabled=True)
conf.parse_args(argv=['--no-xformers'])
conf.xformers_enabled
# True
Any setting can be overwritten by setting an environment variable of
form: "INVOKEAI_<setting>", as in:
export INVOKEAI_port=8080
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 at the top level file:
from invokeai.app.services.config import InvokeAIAppConfig
# get global configuration and print its cache size
conf = InvokeAIAppConfig.get_config()
conf.parse_args()
print(conf.max_cache_size)
Typical usage in a backend module:
from invokeai.app.services.config import InvokeAIAppConfig
# get global configuration and print its cache size value
conf = InvokeAIAppConfig.get_config()
print(conf.max_cache_size)
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 InvokeAIAppConfig.get_config() function
does this:
config = InvokeAIAppConfig.get_config()
config.parse_args() # read values from the command line/config file
print(config.root)
# Subclassing
If you wish to create a similar class, please subclass the
`InvokeAISettings` class and define a Literal field named "type",
which is set to the desired top-level name. For example, to create a
"InvokeBatch" configuration, define like this:
class InvokeBatch(InvokeAISettings):
type: Literal["InvokeBatch"] = "InvokeBatch"
node_count : int = Field(default=1, description="Number of nodes to run on", category='Resources')
cpu_count : int = Field(default=8, description="Number of GPUs to run on per node", category='Resources')
This will now read and write from the "InvokeBatch" section of the
config file, look for environment variables named INVOKEBATCH_*, and
accept the command-line arguments `--node_count` and `--cpu_count`. The
two configs are kept in separate sections of the config file:
# invokeai.yaml
InvokeBatch:
Resources:
node_count: 1
cpu_count: 8
InvokeAI:
Paths:
root: /home/lstein/invokeai-main
conf_path: configs/models.yaml
legacy_conf_dir: configs/stable-diffusion
outdir: outputs
