aseyboldt opened a new issue #8133: Infer_shape_partial for rank 0 arrays URL: https://github.com/apache/incubator-mxnet/issues/8133 In the python interface of mxnet it seems to be impossible to distinguish between an array of unknown shape and an array with known shape of `()`: ```python a = mx.sym.var('a') b = mx.sym.var('b') (a + b).infer_shape_partial(b=()) ([(), ()], [()], []) ``` In this case `b` is known to be a scalar, while `a`'s shape is unknown. Shouldn't it return something like `([None, ()], [None], [])`? If `a` is set to be a scalar, it returns an invalid result: ```python a = mx.sym.var('a') b = mx.sym.var('b') (a + b).infer_shape_partial(a=(), b=(1, 2)) ([(1, 2), (1, 2)], [(1, 2)], []) ``` It identifies the shape of `a` as `(1, 2)`, even though we set it to a scalar. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
