Various problems with dataset 1573 #406

Closed mllg closed 6 years ago

mllg commented 6 years ago

Number of classes is not reported correctly (reported as -1):

 listOMLDataSets(data.name="gisette")

Furthermore, I get a segfault while reading the ARFF.

I get File seems to be of sparse format. farrf does not support this yet!. Maybe using setOMLConfig(arff.reader = "RWeka") does the trick?

There also seems to be a server issue, see https://www.openml.org/d/1573 . The visualization of the target should not be a boxplot.

I opened an issue here https://github.com/openml/OpenML/issues/607 for the number of classes bug. Closing here as the segfault seems to be an farff bug (which I could not reproduce on my machine)? Just reopen here if there issue is not solved.
