a method of determining whether a photograph of a woman is taken from an image

I'm looking for a way to collect SNS images and take out only the ones from the women's photos. Is there any good way?
I have finished collecting images.
Some images are not just corporate logos.

I usually use ruby, so I hope ruby will solve the problem.
You can use a different language to resolve whether it is a picture of a woman or not.

Thank you for your cooperation.
