ERROR: It looks like your system’s Python is “externally managed” (PEP 668).
  • System-wide pip installs are blocked.
  • You must use a virtual environment (venv or conda)

Quick fix:
  $ python3 -m venv llmb_venv
  $ source llmb_venv/bin/activate
  $ ./install.sh

IMPORTANT: You will need this virtual environment if you plan to use 'llmb-run' for launching workloads.
