Issue

I'm trying to install a different version of torch, depending on the CPU. If I'm on the Raspberry Pi, I want to use the wheel from download.pytorch.org, otherwise I can install from pypi. (The reason for this is a cuda-dependency-issue, but that's not the point here).

I have the following in my pyproject.toml

torch = [
    { markers = "platform_machine == 'aarch64'", url = "https://download.pytorch.org/whl/torch-1.13.1-cp310-cp310-manylinux2014_aarch64.whl"},
    { markers = "platform_machine == 'x86_64'", version = "^1.13.1"},
]

The problem is that the marker-logic doesn't work: Poetry just installs the first of the two alternatives, and ignores the markes.

Am I doing something wrong?
