PyPI

A Just-In-Time Compiler for Numerical Functions in Python

Numba is an open source, NumPy-aware optimizing compiler for Python sponsored by Anaconda, Inc. It uses the LLVM compiler project to generate machine code from Python syntax.

Numba can compile a large subset of numerically-focused Python, including many NumPy functions. Additionally, Numba has support for automatic parallelization of loops, generation of GPU-accelerated code, and creation of ufuncs and C callbacks.

For more information about Numba, see the Numba homepage: https://numba.pydata.org and the online documentation: https://numba.readthedocs.io/en/stable/index.html

numba-benchmark's Issues

meet unsupported wheel error on this platform after asv run

Hi, guys, I have a problem when using this repo on my mac (x86_64)

First, I create a conda env as readme said:

> conda create -n numba-benchmark python=3.8 conda-forge::asv
> conda list
# packages in environment at /Users/ld/opt/anaconda3/envs/numba-benchmark:
#

zlib                      1.2.12               h4dc903c_2

Then I modified the asv.conf.json with specifying "branches": ["release0.55"], and "pythons": ["3.8"],. Finally, I ran:

   ERROR: numba-0.55.2-cp38-cp38-macosx_12_0_x86_64.whl is not a supported wheel on this platform.

·· Failed to build the project and import the benchmark suite.

My local clang (in /Library/Developer/CommandLineTools/usr/bin) version is 13.1.6, but I think in conda env, my local clang shouldn't be used by these packages in the env. All python 3.8.13 installled by conda env and asv created conda env are both built with clang 12.0.0.

I also found using conda install, I can only install numba=0.55.1, rather than numba=0.55.2. And if I use pip install, the installed numba package is numba-0.55.2-cp38-cp38-macosx_10_14_x86_64.whl, which is macosx_10_14, rather than macosx_12_0

I tried a few hours in this problem, but I didn't solve it right now. Any idea?
