GrapChi: Rating2 Under Toolkit

User 199 | 4/4/2014, 3:35:35 PM

Hi, how do we use ./toolkits/collaborative_filtering/rating2 - I get the error message

rating2: ../../src/util/cmdopts.hpp:67: std::string graphchi::getconfigoption_string(const char*): Assertion `false' failed. ERROR: could not find option algorithm from config.Aborted (core dumped)

I am able to use Lanczos SVD without any problem. Do I need extra configuration for rating2?

Please send us the full command line you used. This error says you did not specify the algorithm type (using --algorithm=svd)

OK, that option fixed one problem and now I have another:

Full cmd line

The command creates all SVD output, it cannot move on to the next step. I am not sure why it tries to open "" instead of "".

The output message is garbled. The rating application does not find the output of svd. Please send us the full command for running svd.
