# Add python file and directory
ADD main.py .

# upgrade pip and install pip packages
RUN pip install --no-cache-dir --upgrade pip && 
    pip install --no-cache-dir numpy 
    # Note: we had to merge the two "pip install" package lists here, otherwise
    # the last "pip install" command in the OP may break dependency resolution...
