Originally posted by **sjepsen395** July 18, 2024 Hi All Does anyone know how to get around the error "ValueError: columns cannot be a set" when calling pyemu.ParameterEnsemble.from_parfiles(pth_pst, parfile_names)? Input argument pth_pst = path to PEST control file, parfile_names = list of parameter value file paths. My parameter value files don't contain all parameters in my PCF, only the adjustable ones (i.e., not the fixed or tied parameters). Is this problematic for the method? PEST++ IES does not seem to mind as long as the adjustable parameters are in there, so I'm not sure why there would be a problem. Thanks, Steve
