How to use batch_images in FaceSwapUnit

[jiyoon0630]

Hi.

I was following faceswaplab_api_exambple.py and I'd like to ask how to use batch_images in FaceSwapUnit.

In api_utils.py, batch_images means "list of base64 batch source images" which can be used for blending multiple user images.

However, if I set batch_images as a list of base64 images, then validation error comes like below.

unit1 = FaceSwapUnit(
    source_img=pil_to_base64("user1.png"),  
    batch_images=[pil_to_base64('user1.png'), pil_to_base64('user2.png')]
)

ValidationError: 1 validation error for FaceSwapUnit
batch_images
wrong tuple length 2, expected 1 (type=value_error.tuple.length; actual_length=2; expected_length=1)

I've check that the error comes from Tuple[str]. So I tried to change it to Tuple[str, ... ] or List[str], but it causes same error while requesting.

{'detail': [{'loc': ['body', 'units', 0, 'batch_images'],
'msg': 'wrong tuple length 2, expected 1',
'type': 'value_error.tuple.length',
'ctx': {'actual_length': 2, 'expected_length': 1}}]}

Can you explain how to use batch_images?
