DickJC123 commented on issue #14954: broadcast_to() behavior change after new 0D and uninitialized shape support added? URL: https://github.com/apache/incubator-mxnet/issues/14954#issuecomment-494640010 Sorry for not getting to the review yet (sidetracked preparing issue 15034). During my review tomorrow, I'll be looking to see that a serialized NDArray (and its shapes) can be interpreted purely on the state of the file, without knowing the 'numpy compatibility mode' of the writer, and without the reader being in a particular mode. I'm not sure if this can be achieved with the current set of magic numbers. I'm assuming there's value in being able to save NDArray's with both unknown and 0 dims and dim-sizes going forward.
