DEP: Next step in scalar type alias deprecations/futurewarnings #22607
Conversation
Finalizes the scalar type alias deprecations making them an error. However, at the same time adds a `FutureWarning` that new aliases will be introduced in the future. (They would eventually be preferred over the `str_`, etc. version.) It may make sense, that this FutureWarning is already propelled soon since it interacts with things such as changing the representation of strings to `np.str_("")` if the preferred alias becomes `np.str`. It also introduces a new deprecation to remove the 0 sized bit-aliases and the bitsize `bool8` alias. (Unfortunately, these are here still allowed as part of the `np.sctypeDict`).
@rgommers in the spirit of having a chance to get this into the next release (since you marked the issue for that), maybe you can have a look/review? I did feel like adding that |
@rossbar not sure it matters, but circleCI is showing a lot of these warnings:
I am a bit confused by it, I think they may be coming from the Parameter types, like:
which seems strange? CI doesn't fail, but should I worry about it? |
Yeah that is a lot of warnings. I wouldn't think it's related to the parameter descriptions as that's only parsed by numpydoc and these warnings are originating from autosummary. From the warning it looks like this is coming from however autosummary does object discovery, but I'll have to take a closer look. |
Thanks @seberg!
That looks like a good idea to me.
This seems less desirable. |
To be clear, |
Right now, I thought mainly that it may be useful to have the option, but lets see:
The big problem I am aware of is Cython, since it has the following (and equivalent unsigned):
And somehow, such use needs to transition. Maybe |
Hmm, such integer puzzles always hurt my head. Removing
Some relevant content from the 1.20.0 release notes:
We are still missing a good guide to this I think, I usually have to dig up https://github.com/scikit-learn/scikit-learn/wiki/C-integer-types%3A-the-missing-manual. My understanding of our current situation is:
So after writing this: your point is that |
Yes, that is my point. The old In any case, I think We don't have to follow through, but adding a future-warning opens us up a tiny bit more to that, I think. |
Okay, makes sense then, +1 from me. Let me review the rest of this PR then. |

Overall LGTM, just some minor comments. Removing finfo.machar
is the main one; in case of time pressure before release that can also be done in a follow-up.

np.finfo().machar
was deprecated at the same time, can you remove that as well?

Not sure what this comment means. allTypes
is not in the main namespace, and I think we'd like to keep it that way. Remove?

allTypes is what ends up in the main namespace:

This change replaces references to a number of deprecated NumPy type aliases (np.bool, np.int, np.float, np.complex, np.object, np.str) with their recommended replacement (bool, int, float, complex, object, str). Those types were deprecated in 1.20 and are removed in 1.24, cf numpy/numpy#22607.

This means that users with the latest version of numpy they will face either warnings or errors according to the type that they are using. This affects all the users using numoy > 1.20.0 One of the types was fixed back in September with this [pull](#37817) request [numpy 1.24.0](numpy/numpy#22607): The scalar type aliases ending in a 0 bit size: np.object0, np.str0, np.bytes0, np.void0, np.int0, np.uint0 as well as np.bool8 are now deprecated and will eventually be removed.

This change replaces references to a number of deprecated NumPy type aliases (np.bool, np.int, np.float, np.complex, np.object, np.str) with their recommended replacement (bool, int, float, complex, object, str). Those types were deprecated in 1.20 and are removed in 1.24, cf numpy/numpy#22607.
…ypes ### Problem description Numpy has started changing the alias to some of its data-types. This means that users with the latest version of numpy they will face either warnings or errors according to the type that they are using. This affects all the users using numoy > 1.20.0 One of the types was fixed back in September with this [pull](apache#37817) request [numpy 1.24.0](numpy/numpy#22607): The scalar type aliases ending in a 0 bit size: np.object0, np.str0, np.bytes0, np.void0, np.int0, np.uint0 as well as np.bool8 are now deprecated and will eventually be removed. [numpy 1.20.0](numpy/numpy#14882): Using the aliases of builtin types like np.int is deprecated ### What changes were proposed in this pull request? From numpy 1.20.0 we receive a deprecattion warning on np.object(https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations) and from numpy 1.24.0 we received an attribute error: ``` attr = 'object' def __getattr__(attr): # Warn for expired attributes, and return a dummy function # that always raises an exception. import warnings try: msg = __expired_functions__[attr] except KeyError: pass else: warnings.warn(msg, DeprecationWarning, stacklevel=2) def _expired(*args, **kwds): raise RuntimeError(msg) return _expired # Emit warnings for deprecated attributes try: val, msg = __deprecated_attrs__[attr] except KeyError: pass else: warnings.warn(msg, DeprecationWarning, stacklevel=2) return val if attr in __future_scalars__: # And future warnings for those that will change, but also give # the AttributeError warnings.warn( f"In the future `np.{attr}` will be defined as the " "corresponding NumPy scalar.", FutureWarning, stacklevel=2) if attr in __former_attrs__: > raise AttributeError(__former_attrs__[attr]) E AttributeError: module 'numpy' has no attribute 'object'. E `np.object` was a deprecated alias for the builtin `object`. To avoid this error in existing code, use `object` by itself. Doing this will not modify any behavior and is safe. E The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at: E https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations ``` From numpy version 1.24.0 we receive a deprecation warning on np.object0 and every np.datatype0 and np.bool8 >>> np.object0(123) <stdin>:1: DeprecationWarning: `np.object0` is a deprecated alias for ``np.object0` is a deprecated alias for `np.object_`. `object` can be used instead. (Deprecated NumPy 1.24)`. (Deprecated NumPy 1.24) ### Why are the changes needed? The changes are needed so pyspark can be compatible with the latest numpy and avoid - attribute errors on data types being deprecated from version 1.20.0: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations - warnings on deprecated data types from version 1.24.0: https://numpy.org/devdocs/release/1.24.0-notes.html#deprecations ### Does this PR introduce _any_ user-facing change? The change will suppress the warning coming from numpy 1.24.0 and the error coming from numpy 1.22.0 ### How was this patch tested? I assume that the existing tests should catch this.

Finalizes the scalar type alias deprecations making them an error.
However, at the same time adds a
FutureWarning
that new aliaseswill be introduced in the future.
(They would eventually be preferred over the
str_
, etc. version.)It may make sense, that this FutureWarning is already propelled soon
since it interacts with things such as changing the representation of
strings to
np.str_("")
if the preferred alias becomesnp.str
.It also introduces a new deprecation to remove the 0 sized bit-aliases
and the bitsize
bool8
alias. (Unfortunately, these are here still allowedas part of the
np.sctypeDict
).xref gh-22021
