DeprecationWarning are, by definition, warnings. if your code/your
package code fails because of them, you need to relax whatever check
is been executed. warnings are there to let you know things will
change in the future, they are NOT an indication of anything wrong.

it looks to be a common practice in the "python science" packages to
threat DepWarnings as errors, this is not the correct usage.
