Cannot install on M series Mac

[Michael-ljn]

Hey,

Just tried to install the v.1.1 but pypardiso is listed in the requirements and is not supported on M1 Macs. I assume linear algebra calculation method is covered by the version of brightway install and this new version should work without pypardiso as a requirement.

Hi,

Indeed, Brightway does not come anymore with an accelerator librairy installed out of the box, and people need to install it manually : [ https://docs.brightway.dev/en/latest/content/installation/index.html | https://docs.brightway.dev/en/latest/content/installation/index.html ]

I find it quite bothering : People don't notice they don't have a proper solver and things are just running super slow. That's why I added pypardisio in the requirements, so most users have an acceleration out of the box.

But indeed it breaks on M1.

I can add a condition to only require it on x86 architecture.

Can you please provide the output for the following commands ?

import platform platform.platform() ??

platform.system() ??

platform.architecture() ??

platform.processor() ??

I see, indeed I have some troubles installingscikit-umfpack accelerator for the ARM architecture, and sometimes I get warnings for trying to solve a singular matrix such as this one UmfpackWarning: (almost) singular matrix! (estimated cond. number: 1.55e+12)

Solving the initial (big) LCA calculation can take up to 14mins in my case.... Then for the other calculations it's fortunately it's very fast with lca_algebraic, but still very annoying indeed. Here is the result of what you asked:

'macOS-14.4.1-arm64-arm-64bit' 'Darwin' ('64bit', '') 'arm'

Thanks for the software, it's a very good one!

Hi,

Could you please try to install this version ? [ https://pypi.org/project/lca-algebraic-dev/1.1.1753145.dev0/ | https://pypi.org/project/lca-algebraic-dev/1.1.1753145.dev0/ ]

I have removed the dependency to pypardiso when building for "arm"
