TypeError: module.__init__() takes at most 2 arguments (3 given)

[stoneljsh]

Running with the raw code and here is the following bug:

Traceback (most recent call last):
File "./tools/train_net.py", line 15, in
from datasets.factory import get_imdb
File "/home/liujs/pycaffe/py-faster-rcnn-master/tools/../lib/datasets/init.py", line 7, in
from .kakou import kakou
File "/home/liujs/pycaffe/py-faster-rcnn-master/tools/../lib/datasets/kakou.py", line 21, in
class kakou(datasets.imdb):
TypeError: Error when calling the metaclass bases
module.init() takes at most 2 arguments (3 given)

Would you please share the opinion to fix it?
