turtleizzy commented on issue #15535: mxnet.io.NDArrayIter does not properly function when len(data) * 2 < batch_size and last_batch_handle='pad' URL: https://github.com/apache/incubator-mxnet/issues/15535#issuecomment-511213685 > I was running your code, and it looks like `last_batch_handle` has nothing to do with the error. You'll get the same error whenever your `batch size > 2 * len(data)`. > > ```python > data = mx.nd.arange(5) > > dtIter = mx.io.NDArrayIter(data, batch_size=11) # everything is fine for batch_size upto 10 > for i in dtIter: > print (i.data) > ``` > > prints: > `IndexError: Slicing stop 6 exceeds limit of 5` `last_batch_handle='pad'` does matter because the default value for `last_batch_handle` is `'pad'` and all other options (`roll_over` and `discard`) does not result in exception.
