I have seen and heard of large female green anacondas sizing up people before, indicating they were interested in possibly going for it. However this is very rare and I'm only aware of a couple of these instances and these were exceptionally large annies. Note that they never did actually attack anyone.
Male green anacondas - absolutely not. They do not get nearly as large as females, usually averaging 10 feet while females can push 20 on occasion.
Male and female yellow anacondas - absolutely not. This is the smaller second species of anaconda which average around 10 feet for females and 8 for males.
I have not heard of any responsible owner EVER being eaten by a female green anaconda, and there are documentations for all captive snake owner deaths available online.
Now keep in mind your question was *eating* a person. Killing a person is another story. While still very rare, since green anacondas are generally docile snakes and not aggressive in captivity, there have been deaths from all species and genders of anacondas in captivity. Deaths from yellow anacondas are more common because they have generally bad temperaments as opposed to their gentle larger cousins.
Consider this: deaths from large pet dogs are literally hundreds of times more common than deaths from large snakes.
On a final note, when I say people, I am talking about older teens and adults. Young kids and babies should obviously be kept away from large constrictors no matter the species.
