paddle.vision.models. resnext50_32x4d ( pretrained=False, **kwargs ) [source]

ResNeXt-50 32x4d model from “Aggregated Residual Transformations for Deep Neural Networks”.

Parameters

• pretrained (bool, optional) – Whether to load pre-trained weights. If True, returns a model pre-trained on ImageNet. Default: False.

• **kwargs (optional) – Additional keyword arguments. For details, please refer to ResNet.

Returns

Layer. An instance of ResNeXt-50 32x4d model.

Examples

>>> import paddle
>>> from paddle.vision.models import resnext50_32x4d

>>> # build model
>>> model = resnext50_32x4d()

>>> # build model and load imagenet pretrained weight
>>> # model = resnext50_32x4d(pretrained=True)

>>> x = paddle.rand([1, 3, 224, 224])
>>> out = model(x)

>>> print(out.shape)
[1, 1000]
