    Sorry, what exactly is the problem? Are you running out of memory during execution, or just can't load the data? If your data is market basket type (i.e. binary attributes), are you using sparse ARFF format (this can save a lot of memory)? Runtime and memory consumption can be affected by setting too low a value for the minimum support of item sets - try using higher values to begin with. For binary data, FPGrowth is more efficient and faster than Apriori.

    Cheers,
    Mark.
