Readme for fei-dataiter-0.2.0.0

[back to package description]

mxnet-dataiter

Here is an example of making a Conduit from MNIST dataset.

mnistIter (add @"image" "data/train-images-idx3-ubyte" $ 
           add @"label" "data/train-labels-idx1-ubyte" $
           add @"batch_size" 128 
           nil) :: ConduitData IO (NDArray Float, NDArray Float)

The first argument is provides named parameters for the MXNet Data Iterators. Detailed specification can be found in MXNet API 's python document.

Below is a snapshot of current support in this package.
