bulk install fails

[mabodo]

when doing a bulk install to a raw environment similar to this:

pip install -r requirments.txt

The installation of GPyOpt fails here the trace:

Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/private/var/folders/ww/j0q_jynx6hl_9sr0pzkjlyj40000gp/T/pip-build-divwyilr/GPyOpt/setup.py", line 6, in <module>

        import numpy as np
    ModuleNotFoundError: No module named 'numpy'

Even if requirments.txt have a numpy on it, since is not yet installed the setup.py cannot be open and therefore it breaks.
