Not sure where to report this bug, but this forces me stick with intelpython 2018.0.3. The steps to reproduce are
conda config --add channels intel conda create -n test impi_rt=2019.1
You will find /path/to/envs/test/bin/mpivars.sh has I_MPI_ROOT not substituted correctly.
Or is conda no longer the supported way to install Intel Performance Libraries? If so, what's the most future proof way? Or if it is the best way, where should I report this bug? Thanks.
