ISIS 9.0.0 install issue

[oleg-alexandrov]

ISIS version(s) affected: 9.0.0

Description

ISIS fails to install for me when installing with mamba. After running for more than 30 minutes it fails with:

error    libmamba Could not solve for environment specs
    The following package could not be installed
    └─ isis =9.0.0 * is not installable because it requires
       └─ embree >=3.13,<3.14.0a0 *, which conflicts with any installable versions previously reported.
critical libmamba Could not solve for environment specs

This is for Linux. Anybody had luck with this?

Then only thing that helped is the option --channel-priority flexible. Here's the full command that worked:

mamba create -n isis -c usgs-astrogeology -c conda-forge python=3.12 --channel-priority flexible isis=9.0.0

Likely specifying python upfront is not necessary, and the key fix is the flexibility of channels. If the usgs-astrogeology has an older version of embree, strict priority usually causes problems.

If verified, it may be good to update the installation instructions. Such failures to a lot of time to debug.
