Orthpol-light installation error

[SebastianGonzalez2000]

I have tried installing TransportMaps on my Mac in various different ways including automatic installation and manual installation. However, I always run into the following error:

`Collecting orthpol-light>=1.0.1 (from transportmaps==3.0.8)
  Using cached orthpol_light-1.0.1.tar.gz (22 kB)
  Installing build dependencies ... done
  Getting requirements to build wheel ... error
  error: subprocess-exited-with-error
  
  × Getting requirements to build wheel did not run successfully.
  │ exit code: 1
  ╰─> [21 lines of output]`

I have installed all three requirements successfully:

brew install llvm brew install gfortran brew install open-mpi

But when I try the command pip install --upgrade TransportMaps I get the following stack trace:

I have not been able to find help anywhere else. I would appreciate any ideas on what could be going wrong. Cheers.

Hey Sebastian, it seems like you've already looked at #1 (comment) and tried to best follow steps (albeit for Ubuntu, not Mac)? Can you quickly verify that?

We're a little busy now (@doublestrong is defending his thesis tomorrow!) and we don't have many Macs laying around but if none of this works we can try to get a hold of a Mac and report back with our results.

Can you give the full details of your system to the best of your abilities (OS, fresh conda environment, etc)? It'd be useful to know exactly every command you ran to try to set things up.

[SebastianGonzalez2000]

Thanks for the quick response! This is my current setup:

macOS Big Sur 11.7.7
Fresh virtual environment

Commands:
0) Create virtualenv

python -m venv TRANSPORT_MAPS
source TRANSPORT_MAPS/bin/activate

1. Install Requirements

brew install llvm
brew install gfortran
brew install open-mpi

2. Upgrade pip
   pip install --upgrade pip

3. Install dependencies
   pip install --upgrade numpy cython

4. Attempt to install TransportMaps (This is where I get the error)
   pip install --upgrade TransportMaps

[alanpapalia]

Can you try to build a conda environment from the environment.yml file?

cd NF-iSAM
conda env create -f environment.yml
conda activate NFiSAM
pip3 install --upgrade TransportMaps

You may also have some success actually reaching out to the TransportMaps team, as it seems they're actively maintaining the package. (Not trying to push you elsewhere, just they may be more useful :) )

[SebastianGonzalez2000]

Are all dependencies in the environment.yml file intended to work on a Mac? These packages are causing some errors:

conda env create -f environment.yml

Note: I have tried contacting the TransportMaps team but they I have found them hard to reach through their Q2A page.

Hi, I'm the maintainer of TransportMaps. I take the conversation with Sebastian here.

Sorry for the Q&A, we should take offline the Q&A because it has been plagued with spam for a while.

Regarding your issue. Which version of TransportMaps are you trying to install?

It seems you are trying to install orthpol 1.0.1
That version required quite some work to get it working on macOS.

The new version 2.0.2 should install more easily but I don't know which dependencies are blocking you from upgrading.

[SebastianGonzalez2000]

Hello @daniele-bigoni and @alanpapalia. I decided to work on an Ubuntu 22.04.3 machine instead. Thanks for the help.

[doublestrong]

Thanks, @alanpapalia and @daniele-bigoni, for the help. I just noticed this issue. Good luck @SebastianGonzalez2000. Let us know how we can help. I haven't tried orthpol 2.0.2, but I think it should still work for our code. We are just using TransportMaps to define probability distributions.
