Hi Kamal, The code is written for 1M and 10M dataset Which has delimiter "::" while the file you have specified has "\t" as delimiter Try to run with 1 M dataset If you want to run with this file only then just use this command to change the delimiter
cat ratings.dat |tr -s "\t" "::" >new-ratings.dat -----Original Message----- From: Kamal Ali [mailto:[email protected]] Sent: Friday, January 18, 2013 4:40 AM To: [email protected] Subject: Re: trying to get grouplens example to run right, i realize that at a low level you and i have both localized the error. i guess i wasnt clear. i had expected the data i download per instructions to work consistently with the OOB mahout0.7 code. so there is a mismatch between the format that the code expects & that as is supplied from the grouplens page. i'd rather not embark on a wild goose chase trying to read the grouplens mahout code and then patch the grouplens data to conform to it so i was hoping you may be able to point me to more up to date code or data that would work consistently with each other. [or tell me that this example is N years old and nobody has worked on it and in the meantime grouplen data format has changed] thanks, kamal.
