FilterTagget with Serializer doesn't work - Sample pipeline.py

[andersongni]

System information (version):

• OpenCV 3.2
• Python 2.7.12
• Ubuntu 16.04

This error appears when a FilterTagged sends a TaggedValue to a Serializer instance.
On the latest version, the attribute Oper.tag was removed, thereafter the last parameter tag was removed for the method Node.create_opers(), but it keeps being called on Source.run():

anderson@Inspiron-5423:~/Sucuri/examples/mine$ python pipeline.py 1
Roots [<pyDF.nodes.Source instance at 0x7fcaa0dd6d40>]

Main loop
I am worker 0
Process Worker-1:

opers = self.create_oper(TaggedValue(result, tag), workerid, operq, tag)
TypeError: create_oper() takes exactly 4 arguments (5 given)

Just removing the parameter from the call in Source.run() does not work either, because Serializer uses the tag attribute, which no longer exists:
