Universal2 wheel for macOS

[kuldeepsingh0694]

Does Pillow have a Universal2 whl for any version , im building a python GUI app which keeps failing in pyinstaller build due to incompatible Architecture. Apparently all the other libs im using have universal2 whl (pandas,matplotlib,numpy).

System: macOS 12.4 , Apple Silicon (M1 pro)

Hi. Do you really need universal2 wheels, or will arm64 wheels suffice? We provide macOS arm64 wheels that should work for you on your M1. You can see at https://pypi.org/project/Pillow/#files that we have

• Pillow-9.1.1-cp310-cp310-macosx_11_0_arm64.whl
• Pillow-9.1.1-cp39-cp39-macosx_11_0_arm64.whl
• Pillow-9.1.1-cp38-cp38-macosx_11_0_arm64.whl

I would have thought that numpy does not produce universal2 wheels, as I don't see them at https://pypi.org/project/numpy/#files

Hi, Thanks for the reply, yes i need a universal2 wheel as I'm packing is app to work on both Apple Silicon and Intel Chips for macOS.
Currently pyinstaller cant use arm64 whl to build a universal2 app (Incompatibile Binary Arch Error : PIL is not a fat binary (pillow vesion9.1.1 arm64))

PS: I think numpy stopped producing universal2 for newer build. For that reason I'm using numpy 1.21.6 where universal2 whl is available

and does using lipo with pillow arm64 and [x86_64.whl ] can produce the fat binary?

If you're fine using an old version of Pillow in addition to old NumPy, Pillow 9.0.1 had a universal2 wheel:

• Pillow-9.0.1-cp310-cp310-macosx_10_10_universal2.whl
• https://pypi.org/project/Pillow/9.0.1/#files

Hi ,i have checked this universal2.whl but there are some issue with it (Image import fails on macOS 10.13 with Pillow 9.1.0 #6179)
it throw importerror dlopen () symbol not found flat namespace

this is a new virtualenv , installed the above whl with pip install path.whl , python is 3.10.5 universal2 installer

How about this? Pillow-9.1.1-cp310-cp310-macosx_universal2.whl.zip

I created it using delocate.

from delocate import fuse

in1 = "Pillow-9.1.1-cp310-cp310-macosx_10_10_x86_64.whl"
in2 = "Pillow-9.1.1-cp310-cp310-macosx_11_0_arm64.whl"
out = "Pillow-9.1.1-cp310-cp310-macosx_universal2.whl"

fuse.fuse_wheels(in1, in2, out)

Wait, I think I just had the wrong filename. How about this? Pillow-9.1.1-cp310-cp310-macosx_10_10_universal2.whl.zip

can install now, tell me check few things with it thanks a lot!
