but I m trying for example to create a pex with numpy but and it put in the zip numpy whl Is PEX always put within the whl I m not sure how to create a PEX that will run in a different architecture raspberry pi

bitter-ability-32190 · Answer

You can use PEX to package different architectures You might look into playing around with the options documented in `pex help` ` platform` ` complete platform` and ` manylinux` seem like good candidates for experimentation

prehistoric-rainbow-54138 · Answer

Yes I ve seen the help the the platform but not sure what to provide and the difference between them O is it possible ask an example for creating a pex for ARM f e

<https pypi org project numpy 1 21 6 files> might be an inspiration of what to pass to ` platform`

bitter-ability-32190 · Answer

So something like ` platform=manylinux 2 17 aarch64 cp 3 8 12 cp38` Don t quote me on that I m just using my ` platform` for my machine and trying to substitute values I see on that page

I ve tried f e pex platform arm cp 37 cp37m python python3 7 numpy o a pex

but there s no wheel for that isn t possible to use the source dist

I dont think `arm` is a valid PEP 427 platform tag

bitter-ability-32190 · Answer

`aarch64` is

prehistoric-rainbow-54138 · Answer

still not working

bitter-ability-32190 · Answer

And excuse my naivety but <https en wikipedia org wiki AArch64> makes me think `aarch64` is the 64 bit ARM archectecture

bitter-ability-32190 · Answer

You likely need to pass a `platform` which matches this wheel <https files pythonhosted org packages b7 0d 86662f93102e42545cdf031da4fddf0ace9030ec67478932a628afc5973b numpy 1 21 6 cp37 cp37m manylinux 2 17 aarch64 manylinux2014 aarch64 whl|numpy 1 21 6 cp37 cp37m manylinux 2 17 aarch64 manylinux2014 aarch64 whl>

just a second x

prehistoric-rainbow-54138 · Answer

thank you it did worked for the numpy but then a package I m trying to get need a specific version which only tar gz exists no wheels

prehistoric-rainbow-54138 · Answer

it seems to fail because it couldn t resolved

prehistoric-rainbow-54138 · Answer

using `pex platform linux aarch64 cp 37 cp37m python python3 7 pyrsistent==0 14 11 o a pex`

Yeah so if you use ` platform` then you must have prebuilt ` whl` files for each distribution you use That is because Python does not support cross compiling like building a Linux wheel for NumPy from macOS That s a generic Python limitation not Pex or Pants Are you running Pex from the Raspberry Pi or from a foreign platform
