KafkaError thrown when setting error_cb: Property "error_cb" must be set through dedicated .._set_..() function

[brmc]

After updating confluent_kafka to master, I'm getting an error when setting error_cb:

cimpl.KafkaException: KafkaError{code=_INVALID_ARG,val=-186,str="Property "error_cb" must be set through dedicated .._set_..() function"}

I'm using a basic config:

config = {
        "bootstrap.servers": self.kafka_hosts,
        "error_cb": self.dump_data_on_failure,
        "socket.keepalive.enable": True
    }
    self.producer = Producer(**config)

I installed confluent_kafka directly from the error_cb branch a week or two ago, and it worked as expected, but after upgrading this morning, im getting this error. I still have the previous version installed in a virtualenv and it works, and from looking at the tests, I thought I was doing everything right. Can anyone see what I'm doing wrong?

Make sure the new master version is properly installed.
E.g., python setup.py install -f

Thanks for such a prompt response!

unfortunately I'm still getting the same error after cloning master and installing as recommended. To be sure I uninstalled the other version beforehand. Any ideas?

Oh. wait. it was an id10t error. I was executing the script from the command line

./kafka.py

so the system installation of python was being used rather than the virtualenv installation

sorry for wasting your time, but thanks anyway for your assistance.
