Install

poetry add nicefid

Or, for the old timers:

pip install nicefid

API

nicefid.Features.from_directory(path: Union[str, Path])
nicefid.Features.from_iterator(iterator: Iterator[torch.Tensor])  # NCHW
nicefid.Features.from_path(path: Union[str, Path])
features.save(path: Union[str, Path])

nicefid.compute_fid(features_a, features_b)
nicefid.compute_kid(features_a, features_b)

Usage

Comparing directory with generated images.

import nicefid

features_generated = nicefid.Features.from_iterator(...)
features_real = nicefid.Features.from_directory(...)

fid = nicefid.compute_fid(features_generated, features_real)
kid = nicefid.compute_kid(features_generated, features_real)
