Hi all, I found that when workers >= 2 and ps == 0 worker just return false .
private boolean determineIfDistributed(int nWorkers, int nPS) throws ParseException { // Check #workers and #ps. // When distributed training is required if (nWorkers >= 2 && nPS > 0) { return true; } else if (nWorkers <= 1 && nPS > 0) { throw new ParseException("Only specified one worker but non-zero PS, " + "please double check."); } return false; } should throw a exception ? Kevin, Best Regards
