# Note: we don't use venv here because then per-language build files would need
#   to source this script to have venv python be on the PATH. This would require
#   backport this change to ~30 branches. Instead, we just install pip packages
#   globally here. If this ever breaks, uncomment the following lines, remove
#   sudo from pip install, and do the backports.
