chsin opened a new issue #9755: Feature request: Update Core API
The Core API's
[IO](https://github.com/apache/incubator-mxnet/tree/master/src/io) isn't being
updated to incude
which forces developers for the other languages to write equivalants. If
`NDArrayIter` were in the Core API like `CSVIter`, `ImageRecordIter`,
`MNISTIter`, etc, then it would be called by all languages through each
language's MXDataIter wrapper.
`NDArrayiter` was first introduced as
by @sneakerkg in 2015, but evolved into a general numeric vector iterator that
is useful in languages other than Python, such as in R, which defined but
doesn't implement an [R
as seen in the comments:
* \brief data iterator that takes a NumericVector
* Shuffles it and iterate over its content.
* TODO(KK, tq) implement this when have time.
* c.f. python/io.py:NDArrayIter
It would make more sense to have `NDArrayIter` in the Core, so it can be
called by [R's MXDataIter
Then it could also be accessed by [Scala's MXDataIter
But instead, they had to code and test their own [Scala
The C++ API doesn?t even mention `NDArrayIter` and only has the [C++
