Issue with r-matrix package?

[noahcreany]

Please answer these questions:

Does installing pymer4 into a clean conda environment in any of these
four ways solve the problem? If so, which worked and which didn't?

1. conda create --name test_env1 -c ejolly -c defaults -c conda-forge pymer4
   • Did not work
2. conda create --name test_env2 -c ejolly -c conda-forge -c defaults pymer4
   • Did not work
3. conda create --name test_env3 -c ejolly/label/pre-release -c defaults -c conda-forge pymer4
   • Did not work
4. conda create --name test_env4 -c ejolly/label/pre-release -c conda-forge -c defaults pymer4
   • Did not work

Please provide the following information

1. Description

After creating a Pymer4 Lmer model, it fails becuase of :

RRuntimeError: Error in initializePtr() : 
  function 'chm_factor_ldetL2' not provided by package 'Matrix'

2. Minimal reproducible example

These are the shortest steps that reconstruct the problem.

• the command or commands you ran to to install pymer4: conda install pymer4 ...

• create --name pymer4 -c ejolly -c conda-forge -c defaults pymer4 spyder

• a Python code snippet, the shorter the better, that runs and exhibits the issue

I'm trying to fit a linear mixed effect model. I tried this in both jupyter lab and spyder, both were installed in the same line as conda create --name...., so they followed the same channel priority as the installation of pymer. I tried the following code:

from pymer4.models import Lmer
import pandas as pd

df = pd.read_pickle('df.pkl')

mod = Lmer('Width~ TreatCntrl*PrePost+(1|Trail)', data = df)
print(mod.fit())

In both cases, I get the following error:

RRuntimeError: Error in initializePtr() : 
  function 'chm_factor_ldetL2' not provided by package 'Matrix'

I presume this is coming from the r-matrix package which according to the conda environment is as follows:

r-matrix                  1.6_5             r42hb447869_0    conda-forge

My only suspicion is that this relates to the fact that I'm using an M1 Mac. I saw that you have previously resolved an issue with the M1 and no arch - Issue #38 , but perhaps this is something new? Here is some information about the conda environment pymer4 is installed in.

3. Conda environment

Activate the conda environment that has pymer4 installed, run the
following command in a terminal window, and upload the pymer4_issue.txt file as
an attachment with your issue.

conda list --explicit > pymer4_issue.txt

pymer4_issue.txt

4. System information

Please provide the specifics about your computer hardware architecture and
operating system version. For example:

• Mac OSX, in a terminal window

	$ uname -mprsv
Darwin 23.4.0 Darwin Kernel Version 23.4.0: Wed Feb 21 21:44:06 PST 2024; root:xnu-10063.101.15~2/RELEASE_ARM64_T8103 arm64 arm

I just hit this issue myself on an intel mac. Try this:
conda create --name test -c ejolly -c conda-forge -c defaults pymer4 r-matrix=1.5-3
