Hello everyone,
I've been practicing with the example "Creating a X-ray observation from an in-memory dataset"
However even with simple copy and paste after defining the photons I get this error message:

raise YTUnitOperationError(op_string, inp.units, dimensionless)
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.
Thnak you
