Installation Issue on macOS with Python 3.12

[lucaurelien]

Hello,

A user is facing an issue while trying to install Khiops on macOS with Python 3.12 installed via Conda. Here's a detailed description of the problem:

Environment:

• Operating System: macOS (ARM)
• Python Version: 3.12 (installed via Conda)
• Conda Channels: conda-forge, khiops

Issue Description: The user tried to install Khiops using the following command:

conda install -c conda-forge -c khiops khiops

However, the user encountered the following error:

Collecting package metadata (repodata.json): done
Solving environment: | warning  libmamba Added empty dependency for problem type SOLVER_RULE_UPDATE
failed

LibMambaUnsatisfiableError: Encountered problems while solving:
  - package khiops-10.2.0.0-py312hcb8d3e5_0 requires python_abi 3.12.* *_cp312, but none of the providers can be installed

Additional Information:

• python --version: Python 3.12.2
• which python: /Users/nicolasschlewitz/.local/miniconda3/bin/python
• which conda:

  conda () {
  \local cmd="${1-__missing__}"
  case "$cmd" in
      (activate | deactivate) __conda_activate "$@" ;;
      (install | update | upgrade | remove | uninstall) __conda_exe "$@" || \return
      __conda_reactivate ;;
      (*) __conda_exe "$@" ;;
  esac
  }

• env | grep -i path:

  PATH=/Users/nicolasschlewitz/.local/miniconda3/bin:/Users/nicolasschlewitz/.local/miniconda3/condabin:/Users/nicolasschlewitz/google-cloud-sdk/bin:/opt/homebrew/bin:/Users/nicolasschlewitz/.local/bin:/Users/nicolasschlewitz/.rd/bin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:/usr/local/munki:/usr/local/munkireport

Possible Incompatibilities:

• The Khiops package requires python_abi 3.12.* *_cp312, but this seems to be causing conflicts with other dependencies.

From the issue description, it seems that the installation of the Khiops package from the conda-forge channel has been attempted in the base Conda environment.

Could one try to install Khiops inside a new Conda environment?

Indeed, in the conda-forge documentation one recommends to always install packages from the conda-forge channel inside a new environment that is different from the base Conda environment:

• https://conda-forge.org/docs/user/introduction/
• https://conda-forge.org/docs/user/tipsandtricks/

Consequently, one could update the doc accordingly IMHO.

Closing, this is a documentation issue for the time being: https://github.com/KhiopsML/khiops-doc/issues/35.
