I tried multiple times to install via pip, or conda. Pip gives some missing dll library error, so then I discovered this thread on wheels so I gave a go with conda: #175.
The installation goes flawless, but then importing the package crashes with segmentation fault:

$ ipython
Python 3.10.6 | packaged by conda-forge | (main, Aug 22 2022, 20:38:29) [Clang 13.0.1 ]
Type 'copyright', 'credits' or 'license' for more information
IPython 8.5.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import zfpy
[1]    3650 segmentation fault  ipython

Details of my system:

$ arch
arm64
$ system_profiler SPSoftwareDataType
Software:

    System Software Overview:

      System Version: macOS 12.6 (21G115)
      Kernel Version: Darwin 21.6.0
      Boot Volume: Macintosh HD
      Boot Mode: Normal

I used a clean conda environment for that, just jupyter notebook and numpy installed really.

@da-wad @hmaarrfk Can you please comment on current status of zfp pip and conda packages, particularly with respect to M1?

can you please provide the output of:

pip list

conda list

in your virtual environment

If you are using conda, providing

conda info

also really helps.

As for the status on conda-forge, we have zfpy compiled and built. However, we have no way to test it on any machine.

Hi, unfortunately there is still no pip package for zfpy as Github Actions does not provide M1 silicon to build on. While cross-compilation to arm64 on x86 seems to work, there is an issue with the subsequent linking/delocalization which we haven't managed to solve. If conda packages aren't working either, users of M1 need to do their own compilation at the moment.

I can't spot anything immediately wrong with your environment.

It is quite possible that you are the first testing the package on conda forge.

It is quite possible that we have a bug in it.

I have exactly the same problems on a M1 Mac. If it is helpful, I can also show some more information about my environment.

Meanwhile, I had a lot of problems building from scratch. I want to leave a step-by-step guide here so someone else who sees the problem has an easier time. I'm neither proficient with C-extensions nor CMake, so apologies if this is very hacky.

Building zfpy from scratch

First, clone ZFP repository. Then, do the following (for Python 3.10, change for other python versions accordingly):

mkdir build
cd build
cmake .. -DBUILD_ZFPY=ON \ 
-DCMAKE_BUILD_TYPE=RELEASE \
-DPYTHON_EXECUTABLE:FILEPATH="/opt/homebrew/bin/python3.10" \
-DPYTHON_LIBRARY="/opt/homebrew/Frameworks/Python.framework/Versions/3.10/lib/libpython3.10.dylib" \
-DPYTHON_INCLUDE_DIR="/opt/homebrew/Frameworks/Python.framework/Versions/3.10/include/python3.10"

Under bin you now find a .so library, which you can import with

import zfpy

if you started your python interpreter in the corresponding directory.

To make the package importable from anywhere, first go back to the project root.
Then we change the setup.py file: find and remove the library_dirs attribute completely. Next,
install the package with:

pip install .

Lastly, we manually copy the libs from the build process to a lib path on our system. This might look something like this:

cp build/lib/* /opt/homebrew/Caskroom/mambaforge/base/envs/climate/lib/

If you have no clue where to place the lib, just open up python and try to

import zfpy

Python will complain that it didn't find the library and will show you the content of your rpath.

Hi! I have the same issue as @dokato on my M1 mac. Thanks!

I've been skimming through #175 (comment)

I'm rebuilding the conda-forge package with the OSX_ARCHITECTURES flags specified
conda-forge/zfpy-feedstock#32

If somebody is still interested in conda-forge packages, they can follow the progress there. Other ideas are welcome too.
