AttributeError: "'ASERWorker' object has no attribute 'extract_eventualities_and_relations'"

[qtli]

Dear authors,

Thanks for your useful work!

after running:

aser-server -n_workers 1 -n_concurrent_back_socks 10 -port 8000 -port_out 8001 -corenlp_path "stanford-corenlp-3.9.2" -base_corenlp_port 9000

then I call the extract_eventualities_and_relations function, like:
client.extract_eventualities_and_relations(text)

but I encounter the following error:
AttributeError: "'ASERWorker' object has no attribute 'extract_eventualities_and_relations'"

could you help me to solve it? thanks!
