Answer 1

You should use this, it's functional for me at moment.

report.ipynb : merged.ipynb
    ( bash -c "source ${HOME}/anaconda3/bin/activate py27; which -a python; \
        jupyter nbconvert \
        --to notebook \
        --ExecutePreprocessor.kernel_name=python2 \
        --ExecutePreprocessor.timeout=3000 \
        --execute merged.ipynb \
        --output=$< $<" )
