Detailed numerical results may be sensitive to the exact versions of third party numerical libraries. If you are not using the standard Conda environment you may encounter issues when running the validation demo.

Compiling some packages—in particular afw—require large amounts of RAM to compile. This is compounded as the system will automatically attempt to parallelize the build, and can cause the build to run extremely slowly or fail altogether. On machines with less than 8 GB of RAM, disable parallelization by setting EUPSPKG_NJOBS=1 in your environment before running eups distrib.
