# HOW TORCH IS HANDLED:
#   Docker:  torch is pre-installed in a separate layer BEFORE this file runs:
#              RUN pip install torch --index-url https://download.pytorch.org/whl/cpu
#            pip will then skip the torch line below (version already satisfied).
#   Local:   Run manually first:
#              pip install torch --index-url https://download.pytorch.org/whl/cpu
#            Then: pip install -r requirements.txt
