Hi Alex, Sorry for the trouble--I'll see if I can figure out what's gone wrong on this end. It looks like you're running yt 3.2--can you tell me what version of NumPy you are running?

Hello everyone,
I've been practicing with the example "Creating a X-ray observation from an in-memory dataset" from here http://yt-project.org/doc/analyzing/analysis_modules/photon_simulator.html
However even with simple copy and paste after defining the photons I get this error message:

YTUnitOperationError: The subtraction operator for YTArrays with units (keV) and (1) is not well defined.
Any ideas? I am new to yt and i can't see something wrong.
