[bug#55060] [PATCH 0/6] gnu: Add python-pyvista.

[bug#55060] [PATCH 0/6] gnu: Add python-pyvista.

[Paul A. Patience]

This patch series adds the PyVista library to Guix.
The latest version of PyVista requires python-meshio 5.2 or later, hence the
update to that package.

Paul A. Patience (6):
  gnu: python-meshio: Remove input labels.
  gnu: python-meshio: Remove trailing booleans.
  gnu: python-meshio: Honor #:tests? flag.
  gnu: python-meshio: Update to 5.3.4.
  gnu: Add python-scooby.
  gnu: Add python-pyvista.

What does this package have to do with Denmark and detectives?

Looking further, ‘Great Dane’ appears to be some dog breed, and I guess
it's a pun on the package name and Scooby-Doo.  However, I don't think
this is useful for users looking for packages that suit their needs.

> +    (description

Isn't this just ‘guix package --list-installed=^python’?
What hardware resources does it report?  CPU models?  Disk
manufacturers?  The attached peripherals?  Non-physical peripherals
like e.g. bluetooth mice?  The amount of ductape holding the computer
together?  Information about the printer?  ...

ALso, lightweight and easy is rather subjective.  Compares to lscpu,
lspci, ..., (which are simple C tools IIUC) depending on python and
python-scipy doesn't seem lightweight to me.  ‘(guix)Synopses and
Descriptions’ recommends staying factual.

Maxime.

The 'python-' prefix is only for library-only python packages.  As it
is a called tool, I assume there is some bin/scooby binary that the
user would run?

Are these sufficient?  According to
<https://github.com/banesullivan/scooby/blob/main/requirements.txt>,
there is also a dependency on 'psutil' and 'mkl'.  I have also found
references to those in non-test code.

vtk is (among other things) a Python library, try building vtk and
looking into lib/python3.9/site-packages/vtk.py.

As such, shouldn't 'vtk' be in propagated-inputs, such that when
dependents use 'python-pyvista', the vtk libraries will actually be
found?

Maxime

Hello Maxime,

I will reply to all of your comments below.

It may be called a tool, but it is only a library, meant to be used from
other libraries.
The readme describes the basic usage as follows:

  import scooby
  scooby.Report()

The setup.py file lists psutil and mkl in extras_require, meaning they
are optional.
mkl (https://pypi.org/project/mkl/) is released under the Intel
Simplified Software License, which I suspect is ideologically
incompatible with Guix (and therefore not already packaged for Guix), so
I didn't include it.
I omitted psutil just because I was omitting mkl, but I can add it as a
propagated input.

It seems the test suite expects the import of a missing package to throw
an OSError instead of a ModuleNotFoundError, which is not the case at
least on Python 3.9.9.
I don't know if it was different before.
I can add a comment to that effect.

The synopsis and description are taken wholesale from Scooby's readme.
However, I can rewrite them.

vtk.py is indeed there.
Also, I am able to "import vtk" in a Python repl.
I'm not sure why the sanity check cannot find vtk.py, then.
This sanity check issue also plagues the python-vedo package, and I
don't know how to fix it.
(However, obviously the last line of the comment is incorrect.)

I fixed this in the v2 series.

This version incompatibility seems like something upstream needs to
know about.  I've commented upstream at
<https://github.com/banesullivan/scooby/pull/74>.

The manual has the following to say about optional dependencies:

   • If a Python package has optional dependencies (‘extras_require’),
     it is up to you to decide whether to add them or not, based on
     their usefulness/overhead ratio (*note ‘guix size’: Submitting
     Patches.).

I don't know if this changes anything here.

Ok -- the pypi.org page even says ‘proprietary license’!

A guess: maybe whatever 'sanity-check' indirectly uses, expects the
dependencies to have an 'egg-info', which appears to be the case for
(most?) python-build-system packages, but not for whatever vtk does.

Upstream says we need to add 'pyvips' as listed in

How would I add a python-pyvips native input that doesn't actually
depend on the vips package?
From my understanding of banesullivan's explanation [1], the test checks
for the presence of pyvips in the absence of vips.

I suppose a python-pyvips-for-python-scooby that inherits from
python-pyvips while removing its propagated inputs would do.

Best regards,
Paul

AFAICT, python-pyvips does not currently exist, at least according to
"guix show python-pyvips".  That said, maybe it could be depropagated
(maybe there's no need for a package variant)?

Maxime.

I would have to package it (I'm currently doing so).

Do you mean with a package transformation directly in python-scooby's
native inputs?

No, I mean modifying the python-pyvips package definition to move
'vips' from 'propagated-inputs' to 'inputs' (as-is, this might cause
problems as 'python-pyvips' might then not find 'vips', but such things
can often be resolved by sufficient application of 'substitute*').

Greetings,
Maxime.

[bug#55060] [PATCH v4 0/8] gnu: Add python-pyvista.

[Paul A. Patience]

Fixed Scooby's pyvips test.
Scooby actually requires a pyvips package that is completely missing its VIPS
dependency, so I don't think there is a way around having a pyvips variant
just for Scooby.

I couldn't figure out how to build the C extension for pyvips, but that's not
relevant for Scooby; I added the package just to inherit from it in Scooby's
pyvips variant.
It could be changed in the future.
For now what's installed is the CFFI version.

I also couldn't figure out how to get some tests to pass with pyperf.
It seems like it should be easy to fix, though.

bug#55060: [PATCH 0/6] gnu: Add python-pyvista.

[Ludovic Courtès]

Hi,

"Paul A. Patience" <paul@apatience.com> skribis:

> Fixed Scooby's pyvips test.
> Scooby actually requires a pyvips package that is completely missing its VIPS
> dependency, so I don't think there is a way around having a pyvips variant
> just for Scooby.
>
> I couldn't figure out how to build the C extension for pyvips, but that's not
> relevant for Scooby; I added the package just to inherit from it in Scooby's
> pyvips variant.
> It could be changed in the future.
> For now what's installed is the CFFI version.
>
> I also couldn't figure out how to get some tests to pass with pyperf.
> It seems like it should be easy to fix, though.

OK.  Looks like future-work items to me, not blockers.

> Paul A. Patience (8):
>   gnu: python-meshio: Remove input labels.
>   gnu: python-meshio: Remove trailing booleans.
>   gnu: python-meshio: Honor #:tests? flag.
>   gnu: python-meshio: Update to 5.3.4.
>   gnu: Add python-pyperf.
>   gnu: Add python-pyvips.
>   gnu: Add python-scooby.
>   gnu: Add python-pyvista.

Applied, thanks!

Ludo’.
