scglue.models.data.ArrayDataset

class scglue.models.data.ArrayDataset(*arrays, getitem_size=1)

基类：Dataset

Array dataset for numpy.ndarray and scipy.sparse.spmatrix objects. Different arrays are considered as unpaired, and thus do not need to have identical sizes in the first dimension. Smaller arrays are recycled. Also, data fetched from this dataset are automatically densified.

参数:

*arrays (typing.Union[numpy.ndarray, scipy.sparse._matrix.spmatrix]) – An arbitrary number of data arrays

备注

We keep using arrays because sparse tensors do not support slicing. Arrays are only converted to tensors after minibatch slicing.

方法

accept_shuffle	Accept shuffling result
propose_shuffle	Propose shuffling using a given random seed
random_split	Randomly split the dataset into multiple subdatasets according to given fractions.

属性

arrays	Internal array objects
