classificationlearner app does not start

1 view (last 30 days)
first of all, sorry for my bad English and i'll try my best to express my question.
I am using Matlab with Linux ubuntu to do some machine learning.
If I type "classificationLearner " , app doesn't start. It doesn't show any error, but keep staying at 'busy' status.
I can't pause or stop, so I have to close Matlab and start again.
Does anybody know solution for this?

Perhaps your preferences directory has become corrupted. Maybe try deleting the preferences directory and restarting MATLAB.
To find the preferences directory, type:
>> prefdir
Delete the folder and then restart MATLAB. This will force MATLAB to regenerate it again.

Thanks. I upgrade ubuntu from 14 to 18, and it worked.
