Not sure if it's a bug in TC or LAB...

Best,

I just ran the examples on my machine without problems.

I have seen this exception before when no documents could be found by the 
reader.
In my case, the logging output says:
"INFO: Found [16] resources to be read"

In your case, does it say "[0]"?
In this case, the input data is not found which might indicate some 
configuration problem in your project.

Thanks, so the problem really was a wrong working directory. Maybe the 
experiment should fail sooner if there are no instances. For example, if I run 
TwentyNewsgroupsRaw, it fails with:

Information: Found [0] resources to be read

Which gives me a clear advice that I'm doing something wrong. That was not 
clear from the stacktrace in the previous case.

Good that this has been resolved.

I agree that experiments should fail with a meaningful exception if no input 
documents are found.

Could you open a new issue for that?
