[dpnp.ndarray] Issue with `.view()`

[abagusetty]

Doc says view functionality is available: https://github.com/IntelPython/dpnp/blob/master/doc/reference/ndarray.rst
But looks like there isnt any in the implementation

Also some instances here: https://github.com/IntelPython/dpnp/blob/master/dpnp/dpnp_utils/dpnp_utils_einsum.py#L948

I was wondering if we can get a similar functionality as numpy/cupy .view()

@abagusetty, thank you for bringing that up.

Currently it is TODO, but not implemented yet in dpnp.
Here is a link to the rendered documentation where is no view() method listed.

At the first glance it seems as it can be implemented in dpnp, but need to look deeply.

Thanks @antonwolfy

@antonwolfy I tried this latest commit and came across this error. Here the out was of type: <class 'dpnp.dpnp_array.dpnp_array'>

@abagusetty, could you please share the example where you got that error?

@antonwolfy Sorry, I got confused with a wrong PR. It wasnt related to view() but with .data & .data.ptr attributes. Created a newer issue for tracking here: #2532
