Usage
First, install the CHAMP package into your python environment. If you're creating a new environment for CHAMP, be sure you also specify the version of torch you want with CUDA support, or else this will try to run only on CPU.
pip install git+https://github.com/painebenjamin/champ.git
Now, you can create the pipeline, automatically pulling the weights from this repository, either as individual models:
from champ import CHAMPPipeline
pipeline = CHAMPPipeline.from_pretrained(
"benjamin-paine/champ",
torch_dtype=torch.float16,
variant="fp16",
device="cuda"
).to("cuda", dtype=torch.float16)
Or, as a single file:
from champ import CHAMPPipeline
pipeline = CHAMPPipeline.from_single_file(
"benjamin-paine/champ",
torch_dtype=torch.float16,
variant="fp16",
device="cuda"
).to("cuda", dtype=torch.float16)
Follow this format for execution:
result = pipeline(
reference: PIL.Image.Image,
guidance: Dict[str, List[PIL.Image.Image]],
width: int,
height: int,
video_length: int,
num_inference_steps: int,
guidance_scale: float
).videos
# Result is a list of PIL Images
Starting values for num_inference_steps
and guidance_scale
are 20
and 3.5
, respectively.
Guidance keys include depth
, normal
, dwpose
and semantic_map
(densepose.) This guide does not provide details on how to obtain those samples, but examples are available in the git repository.
