PhanTask commented on issue #9181: How to make a signed float32 multi-channel input .rec file for ImageRecordIter? URL: https://github.com/apache/incubator-mxnet/issues/9181#issuecomment-353775166 @zhreshold Thank you for your suggestion. But it seems `mxnet.io.NDArrayIter` doesn't have any ready-made functions to achieve image-like data augmentation. Is that mean I can only write some augmentation algrithm manually? I'm just very curious about the possibility of making float grid data as fake image inputs since ImageRecordIter and mxnet can handle float input.
