How do I create a positive training sample by combing files??

I have converted 2 csv files into arrays in the hopes that I can create a positive training sample. Could someone help me find a way to combine anchors and matches, so that they are a positive training sample. This would be hugely appreciated as I am quite stuck.

## Convert csv to tensor

anchor = train
anchors = np.array(anchor)
match = train2
matches = np.array(match)

# Create positive training sample
