mxnet.gluon.data.vision.datasets.ImageRecordDataset

class mxnet.gluon.data.vision.datasets.ImageRecordDataset(filename, flag=1, transform=None)[source]

A dataset wrapping over a RecordIO file containing images.

Each sample is an image and its corresponding label.

Parameters:
  • filename (str) – Path to rec file.
  • flag ({0, 1}, default 1) – If 0, always convert images to greyscale. If 1, always convert images to colored (RGB).
  • transform (function, default None) –

    A user defined callback that transforms each sample. For example:

    transform=lambda data, label: (data.astype(np.float32)/255, label)
    
__init__(filename, flag=1, transform=None)[source]

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(filename[, flag, transform]) Initialize self.
transform(fn[, lazy]) Returns a new dataset with each sample transformed by the transformer function fn.
transform_first(fn[, lazy]) Returns a new dataset with the first element of each sample transformed by the transformer function fn.
