It is a predefined workflow in Knime library.

When I try to start it, says that “Unable to read spec from file”. I defined the location of file accurately.

What is the problem here?

Is there a way to download this dataset from somewhere else?

Thanks,
Have a nice day

Hi @kilincali35 -

Are you by chance using an older version of KNIME? Sometimes that will cause this error to pop up.
