Mismatched Shapes in Value Error

[ChaiBapchya]

Description

Shapes given in the Value error seem to be mismatched between expected and got

Python

Compiler: visual studio

MXNet commit hash: 769165b

Error Message:

Traceback (most recent call last):

ValueError: Shape inconsistent: expected () vs got (1,)

Minimum reproducible example

mx.nd.array(1)

Correct way of initialization right now is to feed a list,

>>> a=mx.nd.array([1])
>>> a

[1.]
<NDArray 1 @cpu(0)>

Shape of such an NDarray is

>>> a.shape
(1,)

Meaning, it expects (1,)
However, when we feed ()
It should give error

ValueError: Shape inconsistent: expected (1,) vs got ()

Fix in PR #12678 (Ref: #12677 (comment))

[vrakesh]

@ChaiBapchya can this be closed as well?

[ChaiBapchya]

Um, the PR doesn't address it and the question is still unanswered. I personally think it's mismatched. But wanted to confirm it. In that case, it's a simple change for PR.

[zhreshold]

Yep, the order is wrong, could you open a PR to fix it, since the last conversation is closed. @ChaiBapchya
