Unable to launch MEKA1.9.6 GUI #76

Closed wghx closed 2 years ago

wghx commented 2 years ago

Hello, I have reviewed issue 69, but I am still unable to launch MEKA1.9.6 GUI in Win10 by double clicking the run.bat file. I have inserted the path to java at the top of the batch file as follows: "set /p path=[C:\Program Files\Java\jdk-18.0.1.1\bin1];%path%" I have updated the JAVA_HOME environment variable. I uninstalled WEKA3.8.5 in case it was conflicting. When I launch MEKA I now get a command prompt window displaying various programs that use Java.

Any help much appreciated. Thank you. Warren

It says bin1 in the path. Is that correct?

Also, try with Java 11 instead of 18.

wghx commented 2 years ago

Hi, The path is actually bin, that's my typo error here. I have since downloaded 1.9.5 and that launces fine without adding path to Java at the top of the batch file. I then extracted 1.9.6 again from the zip, & this time did not add path to Java at the top of the batch file, and it still does not lauch; CMD screen appears for 2secs then disappears.

Rather than double clicking on the batch file, launch the batch file from a command prompt. Check if there is an error message.

Can you list the content of the lib directory?

wghx commented 2 years ago

I can't find the lib direcory in MEKA1.9.6, although I can see it in 1.9.5.

Did you download the source zip file rather than the release one (meka-release-1.9.6-bin.zip)?

What was the link that you used for downloading? I tried both, the one hosted on Github and the one on Sourceforge.net and they both work for me (under Linux).

This is the content of the meka-release-1.9.6 directory after decompressing the release zip:

api/
data/
lib/
LICENSE.txt
run.bat
run.sh

Tutorial.pdf

I had the source. I've now downloaded the release and it starts up fine under Win10. Is there anywhere that I can download other Multi-Target classifiers that output the numeric class? Thank you.

AFAIK, there are no classifiers in Meka that do regression.
