UCIHousing¶

class paddle.text.datasets. UCIHousing [源代码] ¶

该类是对`UCI housing <https://archive.ics.uci.edu/ml/datasets/Housing>`_ 测试数据集的实现。

参数¶

data_file（str）- 保存数据的路径，如果参数:attr:`download`设置为True，

可设置为None。默认为None。 - mode（str）- 'train'或'test'模式。默认为'train'。 - download（bool）- 如果:attr:`data_file`未设置，是否自动下载数据集。默认为True。

返回值¶

Dataset，UCI housing数据集实例。

代码示例¶

          import paddle
from paddle.text.datasets import UCIHousing

class SimpleNet(paddle.nn.Layer):
    def __init__(self):
        super(SimpleNet, self).__init__()

    def forward(self, feature, target):
        return paddle.sum(feature), target


uci_housing = UCIHousing(mode='train')

for i in range(10):
    feature, target = uci_housing[i]
    feature = paddle.to_tensor(feature)
    target = paddle.to_tensor(target)

    model = SimpleNet()
    feature, target = model(feature, target)
    print(feature.numpy().shape, target.numpy())
