Question about IF-BPR: parameter batch_size is invalid!

[Coder-Yu]

hi, thanks for your interest. I have updated the config file, you can download the new version and try again. Kindly remind you that you have to pick out the negative samples and organized them as a file because IF-BPR needs to read negative samples. Besides, all the datasets used in our paper can be found by accessing https://github.com/CQU-CSE/DatasetCollection. In addition, there is a unintentional mistake in our paper that we recorded users that have less than 20 ratings as the cold users while in the paper we wrote 10.

I compared the old and new versions of IF-BPR.conf as if there was no difference...
Then I read the source code of IF_BPR(IF_BPR.py), and placed the ratings_n.txt containing the negative sample in the dataset/epinions/ directory. The same error persists. QAQ

def readNegativeFeedbacks(self):
    ...
    filename = self.config['ratings'][:-4]+'_n.txt'
    with open(filename) as f:
    ...

It's OK now. Sorry for the mistake.
