>>> from ophyd.areadetector.detectors import SimDetector
>>> s = SimDetector("SIM:", name="SIM")
>>> s.cam.acquire.put(1)

raise NotImplementedError
NotImplementedErrorThis does not happen when installing via conda-forge.
@flowln noticed that here there is a fallback to "dummy" in case neither caproto nor pyepics are installed.
The error doesnt happen in conda-forge installations since they come with pyepics and caproto.
Maybe adding these as dependencies in setup.py would fix this?
