Pybind11 is not installed.

Very likely, the build process after this message will fail.
Simply press Ctrl+C and type
python -m pip install pybind11
to fix this. If you don't, the build will continue
in a few seconds.

Mako is not installed.

That is not a problem, as most of PyOpenCL will be just fine
without it. Some higher-level parts of pyopencl (such as
pyopencl.reduction) will not function without the templating engine
Mako [1] being installed. If you would like this functionality to
work, you might want to install Mako after you finish
installing PyOpenCL.
Simply type
python -m pip install mako
either now or after the installation completes to fix this.

Это проблема с последней версией pyopencl, опубликованной в PyPI.Последняя версия в репозитории github уже решает эту проблему, используя новый ExtensionUsingNumpy вместо старого NumpyExtension в setup.py::setup().
Тем не менее, если зависимости Mako и pybind11 неустановлен, установка pyopencl не удастся.Почему они также не обрабатываются setup.py/setuptools?
