Hi Manuel,
How did you run weka? Did you use the standalone version of the website of
did you use the package manager to install the plugin?
@jan: Can we now remove the standalone version from the website and use the
package from now on?
Thanks,
Joaquin

@manuel: did you try clearing the cache? We did a lot of changes in the
caching mechanism recently.
The cache is in a .openml folder in your home dir.
Cheers,
Joaquin

It was a clean standalone Weka version and then I installed the OpenML plugin from the package repository. I only got that error with tasks using dataset 17 so far. I tried to clean the cache but it happened again.

Interesting. Jan, can you take a look?

I mean, it's not urgent. I will use other datasets for the demo, but just take a look when you can :)

We have released several new versions of the apiconnector in the mean time. Please check if this is still an issue.
