Re: [DL-Learner discussion] Null Pointer Exception in FastInstanceChecker.java:202 - Revision 3518: /branches/1.0.1

[Jens L. <le...@in...>]

Hello An,

it seems that you are using a mixture of new and old code in your local
version of DL-Learner. Note that we performed many significant changes
in the last year, so using an older version of the conf parser in
combination with new algorithms etc. won't work. Please try to do a
clean fresh SVN checkout of DL-Learner trunk and then verify whether the
problem still exists.

Note that the current SVN revision is 3522 (as of 10pm CET today). If
your confparser package is from revision 2322, then that is from
December 2010, which is before the change of the conf file syntax
announced in the DL-Learner-1.0-alpha-1 release. That would explain the
problems you get. You can subscribe to
https://lists.sourceforge.net/lists/listinfo/dl-learner-svn to always
get the latest SVN changes, which will help you to stay up to date.

>From your questions, it seems that you perform non-trivial changes or
additions to DL-Learner. In that case, it may be useful for our research
groups to work more closely together. If we do this, then I could give
you developer access to DL-Learner and you could perform your changes in
a separate branch, which you could synchronise with the trunk
occasionally (or eventually we could move them to the trunk itself).

Kind regards,

Jens
