One of my engineers uses the package

tensorflow-ranking

which has a dependency on

tensforflow

. On M1 laptops, engineers install

tensforflow-macos

not

tensorflow

. We get around this by

pip

installing it with

--no-deps

. I tried checking to see if I could specify that flag in

requirements.txt

and solve this outside of

pants

but haven't found anything. Is there a way I can add

--no-deps

to

tensorflow-ranking

in

pants

?

Nope. Neither in Pants nor Pex. You can in Pex (

--intransitive

), but Pex, like Pants is global in that you cannot build up a venv piecemeal. You specify a complete venv all at once with both.

you can make it a platform conditional requirement, i think?

You missed the detail I think Stu.

can’t remember where i saw that recently… looking.

The issue is a transitive dep.

ah, yea. i see what you’re saying.

This is probably just wishful thinking (and me still learning pants) but I can't do something like

"tensorflow-ranking": {
    "dependencies": [
        "//:reqs#tensorflow"
    ]
},  
"tensorflow": {
    "requirements": (
        # Linux or intel Mac
        "tensorflow ~= 2.11.0 ; sys_platform != 'darwin' or platform_machine == 'x86_64'",
        # Mac M1
        "tensorflow-macos ~= 2.11.0 ; sys_platform == 'darwin' and platform_machine == 'arm64'",
    ),
}

in a

BUILD

file right?

@silly-queen-7197 it looks like that's a pure python project: https://pypi.org/project/tensorflow-ranking/#files

Thanks, that's a very pragmatic solution

See here: https://www.pantsbuild.org/docs/python-third-party-dependencies#version-control-requirements

I think the reality is we'll need to just move to remote development so all engineers have an x86 machine (a plus is spinning up machines with gpus too). Fortunately this is on our roadmap

Developing on Linux for Linux is .... sane

@witty-crayon-22786 did you think of this thread? https://pantsbuild.slack.com/archives/C046T6T9U/p1676331663918329

indeed, heh.
