... but this is a problem to do with bad input, it seems. And the book
examples go with 0.5. The bug you are thinking of does not affect anything
written about in the book. 0.5 is the right version to use as far as the
book examples are concerned.

What format is your input? should be "user,item,rating". This evidently
isn't the format you are using.
