This is a repo for configs for MC sample requests.
cmsdriver cannot find pythons if one put 2017FlowMCRequest under ${CMSSW_BASE}/src.
That is because CMSSW will not try to search pythons under ${CMSSW_BASE}/src/path/to/target/python.
It will cease searching on the level ${CMSSW_BASE}/src/path/to/python.
It is better to clone the repo outside ${CMSSW_BASE}.
git clone https://github.com/davidlw/2017FlowMCRequest.git
mv 2017FlowMCRequest/Configuration 2017FlowMCRequest/GeneratorInterface ${CMSSW_BASE}/src
cd ${CMSSW_BASE}/src
scram b
Examples of cmsdriver usage can be found in Configuration/GenProduction/scripts. Parameters for cmsdriver can be found on McM.
