Some TU Datasets do not work - Error when loading · Issue #195 · JuliaML/MLDatasets.jl (original) (raw)

Unfortunately, some TU Datasets can not be loaded. The following example illustrates the problem for dataset "Cuneiform":

using MLDatasets tudata = TUDataset("Cuneiform")

The following error message occurs:
