I can't build the last TAG

I'm trying to build the last tag from bob.blitz so I can use it with the new release of bob.extension, but....

https://gitlab.idiap.ch/bob/bob.blitz/-/jobs/141543

ping @andre.anjos @amohammadi

It's some API compatibility problem with numpy, but everything (bob.blitz and its bob dependencies) was built with numpy 1.13.3.

Can I have some help, please?

Thanks
