The Args object would crap out when trying to retrieve metadata from an image file that did not contain InvokeAI-generated metadata, such as a JPG. This corrects that and returns dummy values (seed of zero, prompt of '') to avoid downstream breakage.

"""Helper class for dealing with image generation arguments.
|
|
|
|
The Args class parses both the command line (shell) arguments, as well as the
|
|
command string passed at the invoke> prompt. It serves as the definitive repository
|
|
of all the arguments used by Generate and their default values, and implements the
|
|
preliminary metadata standards discussed here:
|
|
|
|
https://github.com/lstein/stable-diffusion/issues/266
|
|
|
|
To use:
|
|
opt = Args()
|
|
|
|
# Read in the command line options:
|
|
# this returns a namespace object like the underlying argparse library)
|
|
# You do not have to use the return value, but you can check it against None
|
|
# to detect illegal arguments on the command line.
|
|
args = opt.parse_args()
|
|
if not args:
|
|
print('oops')
|
|
sys.exit(-1)
|
|
|
|
# read in a command passed to the invoke> prompt:
|
|
opts = opt.parse_cmd('do androids dream of electric sheep? -H256 -W1024 -n4')
|
|
|
|
# The Args object acts like a namespace object
|
|
print(opt.model)
|
|
|
|
You can set attributes in the usual way, use vars(), etc.:
|
|
|
|
opt.model = 'something-else'
|
|
do_something(**vars(a))
|
|
|
|
It is helpful in saving metadata:
|
|
|
|
# To get a json representation of all the values, allowing
|
|
# you to override any values dynamically
|
|
j = opt.json(seed=42)
|
|
|
|
# To get the prompt string with the switches, allowing you
|
|
# to override any values dynamically
|
|
j = opt.dream_prompt_str(seed=42)
|
|
|
|
If you want to access the namespace objects from the shell args or the
|
|
parsed command directly, you may use the values returned from the
|
|
original calls to parse_args() and parse_cmd(), or get them later
|
|
using the _arg_switches and _cmd_switches attributes. This can be
|
|
useful if both the args and the command contain the same attribute and
|
|
you wish to apply logic as to which one to use. For example:
|
|
|
|
a = Args()
|
|
args = a.parse_args()
|
|
opts = a.parse_cmd(string)
|
|
do_grid = args.grid or opts.grid
|
|
|
|
To add new attributes, edit the _create_arg_parser() and
|
|
_create_dream_cmd_parser() methods.
|
|
|
|
**Generating and retrieving sd-metadata**
|
|
|
|
To generate a dict representing RFC266 metadata:
|
|
|
|
metadata = metadata_dumps(opt,<seeds,model_hash,postprocesser>)
|
|
|
|
This will generate an RFC266 dictionary that can then be turned into a JSON
|
|
and written to the PNG file. The optional seeds, weights, model_hash and
|
|
postprocesser arguments are not available to the opt object and so must be
|
|
provided externally. See how invoke.py does it.
|
|
|
|
Note that this function was originally called format_metadata() and a wrapper
|
|
is provided that issues a deprecation notice.
|
|
|
|
To retrieve a (series of) opt objects corresponding to the metadata, do this:
|
|
|
|
opt_list = metadata_loads(metadata)
|
|
|
|
The metadata should be pulled out of the PNG image. pngwriter has a method
|
|
retrieve_metadata that will do this, or you can do it in one swell foop
|
|
with metadata_from_png():
|
|
|
|
opt_list = metadata_from_png('/path/to/image_file.png')
