potential BUG in function utils.euclidean_distances()

[Shijie-NLP]

Describe the bug

Hi, I am confused with the flag squared=False in the function utils.euclidean_distances().

According to the declaration, if squared flag is set to True, this function should return squared results. BUT in the code, it is not the case.

why it takes square when this flag is False?

Expected behavior

Do square operation when the argument 'squared' is set to True

Environment (please complete the following information):

POT version: 0.8.2

Thank you!

By default the function compute the euclidean distance (not squared) and that is why there is an sqrt (because the lines above, that are very fast, compute the squared euclidean distance).

I don't think there is a bug here.

Yes, you're right, thanks for your reply. The similar spelling of square and sqrt just misled me.
