Just wanted to follow up that we’ve released a hotfix version 0.15.2, which fixes an MPI-related bug that inadvertently crept in to the last release.

Hi Paul, I am trying to update the python API (after git pull and compiling the 0.15.2 ) using `pip3 install .` The api being installed was named UNKNOWN 0.15.2. I also tried the `python3 -m pip install .` and it gives same results shown below
Do I need to delete all the sources and git clone again instead of git pull in this version?
note: I think I just need to update my pip `pip3 install --upgrade pip`
