Usage: dataset_tool.py [OPTIONS]
|
|
|
|
Convert an image dataset into a dataset archive usable with StyleGAN2 ADA
|
|
PyTorch.
|
|
|
|
The input dataset format is guessed from the --source argument:
|
|
|
|
--source *_lmdb/ Load LSUN dataset
|
|
--source cifar-10-python.tar.gz Load CIFAR-10 dataset
|
|
--source train-images-idx3-ubyte.gz Load MNIST dataset
|
|
--source path/ Recursively load all images from path/
|
|
--source dataset.zip Recursively load all images from dataset.zip
|
|
|
|
Specifying the output format and path:
|
|
|
|
--dest /path/to/dir Save output files under /path/to/dir
|
|
--dest /path/to/dataset.zip Save output files into /path/to/dataset.zip
|
|
|
|
The output dataset format can be either an image folder or an uncompressed
|
|
zip archive. Zip archives makes it easier to move datasets around file
|
|
servers and clusters, and may offer better training performance on network
|
|
file systems.
|
|
|
|
Images within the dataset archive will be stored as uncompressed PNG.
|
|
Uncompresed PNGs can be efficiently decoded in the training loop.
|
|
|
|
Class labels are stored in a file called 'dataset.json' that is stored at
|
|
the dataset root folder. This file has the following structure:
|
|
|
|
{
|
|
"labels": [
|
|
["00000/img00000000.png",6],
|
|
["00000/img00000001.png",9],
|
|
... repeated for every image in the datase
|
|
["00049/img00049999.png",1]
|
|
]
|
|
}
|
|
|
|
If the 'dataset.json' file cannot be found, the dataset is interpreted as
|
|
not containing class labels.
|
|
|
|
Image scale/crop and resolution requirements:
|
|
|
|
Output images must be square-shaped and they must all have the same power-
|
|
of-two dimensions.
|
|
|
|
To scale arbitrary input image size to a specific width and height, use
|
|
the --resolution option. Output resolution will be either the original
|
|
input resolution (if resolution was not specified) or the one specified
|
|
with --resolution option.
|
|
|
|
Use the --transform=center-crop or --transform=center-crop-wide options to
|
|
apply a center crop transform on the input image. These options should be
|
|
used with the --resolution option. For example:
|
|
|
|
python dataset_tool.py --source LSUN/raw/cat_lmdb --dest /tmp/lsun_cat \
|
|
--transform=center-crop-wide --resolution=512x384
|
|
|
|
Options:
|
|
--source PATH Directory or archive name for input dataset
|
|
[required]
|
|
|
|
--dest PATH Output directory or archive name for output
|
|
dataset [required]
|
|
|
|
--max-images INTEGER Output only up to `max-images` images
|
|
--transform [center-crop|center-crop-wide]
|
|
Input crop/resize mode
|
|
--resolution WxH Output resolution (e.g., '512x512')
|
|
--help Show this message and exit.
