Pkg.instantiate() for Flux model zoo

Hi everyone,

I’m trying to get the examples in the Flux model zoo to run, but I’m having problems in the Pkg.instantiate() step mentioned in the README. I’ve tried it using both Julia 1.2.0 and 1.0.5 on Xubuntu 18.04 (64-bit):

On Julia 1.0.5, I get a different error:

Any ideas?

Thanks for any and all help!
