5 years ago After several hours I managed to run it using
java -cp "weka-3-9-3/weka.jar:wekafiles/packages/Auto-WEKA/autoweka.jar" weka.classifiers.meta.AutoWEKAClassifier -t weka-3-9-3/weka-data/iris.arff -timeLimit 1 -no-cvI also bumped into issue #61, so you should make sure to use java 1.8 while using it

4 years ago I seem to be have similar issues using Autoweka on Ubuntu 18.04.3 LTS - works on my Windows virtual PC. It won't run from the GUI; Weka does work OK. Any suggestions? Thanks

4 years ago Merry xmas to you Lars. In an attempt to fix this issue, I installed autoweka ver 2.5, and also tried using two of the arff files that come with weka: airline.arff - produced the message 'Problem running Auto-WEKA: Failed to prepare the experiment.
and breast-cancer.arff - gave no error, but didn't run and gave the log message: 12:23:11: Base relation is now breast-cancer (286 instances) 12:23:11: java.lang.NullPointerException 12:23:16: Started Auto-WEKA for breast-cancer

4 years ago I've updated to Oracle 11.0.5, but get the same errors using Auto-WEKA with the airline.arff and breast-cancer.arff As I'm not an expert on linux and the Oracle site was a bit confusing on how to install java, to check that Oracle 11.0.5 is installed, I checked that Weka still works - it does - and below is terminal info on what version is now showing as the default java;

Hello,
I've been able to run autoweka from Windows with no problems. I am now trying to run it on Ubuntu, but it does not seem to work for me. Would appreciate any help. I am running a simple test on the iris.arff data, and when I use the terminal these are my commands:
java -cp /home/anuraj/autoweka-2.6/autoweka.jar weka.classifiers.meta.AutoWEKAClassifier -t /home/anuraj/weka-data/diabetes.arff -timeLimit 1 -no-cv
I am getting the following error messages:

I've also tried using the GUI. I've installed autoweka via the package manager and tried to run autoweka on iris.arff, but the screen is always stuck at 'autoweka started...' as per the screenshot. I can run autoweka from the GUI on windows with no problems.
Thanks for your help!
