Dataset reading error in H2OAutoML

[diegotxegp]

When I first ran the H2OAutoML framework, that is, using the default AMLB installation, an error appeared indicating that OpenML datasets could not be read in ARFF format. It seems the issue is that Java, which H2O is based on, cannot access the datasets if the import_file function is used in the exec.py file. If this is replaced with upload_file, it works correctly. I’m not sure if it’s the best solution, but it is a solution.

Thanks for reporting this issue. I am not very familiar with H2O myself, so I do not know if something changed in how we should use 'import_file', or if we really should use 'upload_file' instead.
