No classifiers in Weka Explorer

问题

I just found out about weka so I decided to try it out. I downloaded some training data:

@relation weather

@attribute outlook {sunny, overcast, rainy}
@attribute temperature real
@attribute humidity real
@attribute windy {TRUE, FALSE}
@attribute play {yes, no}

@data
sunny,85,85,FALSE,no
sunny,80,90,TRUE,no
overcast,83,86,FALSE,yes
rainy,70,96,FALSE,yes
rainy,68,80,FALSE,yes
rainy,65,70,TRUE,no
overcast,64,65,TRUE,yes
sunny,72,95,FALSE,no
sunny,69,70,FALSE,yes
rainy,75,80,FALSE,yes
sunny,75,70,TRUE,yes
overcast,72,90,TRUE,yes
overcast,81,75,FALSE,yes
rainy,71,91,TRUE,no

When I go to the classify tab in weka and click "choose", it does not have any classifiers and the "choose" dialog is just empty. Do I have to download anything in addition to Weka? I am using Weka 3.8.0

By the way: I already asked that question but i got no answer from it.

回答1:

I fixed it by reinstalling weka in the default path.

EDIT: This is the solution that works for me 100%:

I have a similar sounding issue when using two screens. On my primary monitor the GUI works fine, on the secondary monitor the dialogue boxes get mangled. – S van Balen Dec 29 '16 at 12:31
