Hi, I am getting the following error when I tried to generate data with numOfPerson and numOfyeah option in params.init. Cheers

"loading input for parameter generation find parameter bindings for Persons Traceback (most recent call last): File "paramgenerator/generateparams.py", line 296, in sys.exit(main()) File "paramgenerator/generateparams.py", line 152, in main selectedPersonParams[i] = discoverparams.generate(factors) File "/home/ubuntu/snbDatagen/ldbc_snb_datagen-master/paramgenerator/discoverparams.py", line 129, in generate current_windows = findWindows(factors,paramId,amount,(0,len(factors))); File "/home/ubuntu/snbDatagen/ldbc_snb_datagen-master/paramgenerator/discoverparams.py", line 54, in findWindows initWindow.avg = getAverageCost(data[start:amount], itemgetter(param)) File "/home/ubuntu/snbDatagen/ldbc_snb_datagen-master/paramgenerator/discoverparams.py", line 37, in getAverageCost return float(sum([key(r) for r in rows])) / len(rows) ZeroDivisionError: float division by zero"

Hi @Gillani0 The version of datagen you are using is currently deprecated. It was moved from the public ldbc group to the ldbc-dev group some weeks ago. Please got to https://github.com/ldbc/ldbc_snb_datagen and clone that repository. Read the documentation again, as it now uses hadoop 2.6.0 and the format of params file has changed. Regards, Arnau
