Error in Web Crawl: The example set must contain at least one text attribute

turicum

Hi everybody.

in the following, simple, example, where I process a few pages retrieved by a web crawl, I keep seeing the error "The example set must contain at least one text attribute". The "Nominal to Text", which is suggested as a solution this very same problem in other posts, does not remove the error. Interestingly, there seems to be indeed a 'text' attribute in th example set and the error does not seem to affect the execution of the process. What am I missing?

Thanks!
Marco

Hi,

I am not getting any errors on the latest development version. So the error should be fixed with the next release of RapidMiner and/or the text extension.

All the best,
Marius

Hi Marius

is the development version available? I couldn't find it on sourceforge.

Thanks

Hey, what I call development version is pulled and compiled directly from svn. The source code is available on sourceforge, and our website provides a manual on how to compile RapidMiner from source.

Happy compiling!
