[GitHub] [incubator-mxnet] EnricoMi opened a new issue #20442: TypeError: Block's inputs must be of type `mxnet.numpy.ndarray` ...
EnricoMi opened a new issue #20442:
URL: https://github.com/apache/incubator-mxnet/issues/20442
## Description
One of our [MXNet tests in Horovod](https://github.com/horovod/horovod/blob/master/test/parallel/test_mxnet.py#L721) started to fail on the nightly packages after 2021-06-20. Can you please point me to any breaking changes around that time that might cause this error and need some adoption on our side?
TypeError: Block's inputs must be of type `mxnet.numpy.ndarray`, while got output type <class 'mxnet.ndarray.ndarray.NDArray'>

Yes, using `x = mx.np.ones((5, 4, 10, 10))` is still compatible with MXNet 1.x.

Hi @barry-jin, thanks for the quick and precise reply. Is that fix backward compatible with MXNet 1.x?

Hi @EnricoMi , after #20262 being merged, MXNet2.0 will switch to use Gluon2.0 API and deprecate all the use of legacy NDArrays and ndarray/symbol operators in Gluon Blocks/Layers. In your case, you can just change `x = mx.nd.ones((5, 4, 10, 10))` to `x = mx.np.ones((5, 4, 10, 10))` because in current Gluon2.0, only mxnet.numpy arrays are allowed.
For more detailed information, you can follow the migration guide [here](https://hackmd.io/@BarryJin/ryjIgg-2_).
