Hi John,
thank you for your time and help.
I used conda to install yt.
I am using Ubuntu 14 LTS but I am a newbie.
Again, thank you.
Alex

Hi Alex,
Sorry—the delays on my end are longer than yours.
We’ve fixed this bug, but I’m still a little unclear as to how you installed yt.
You’re using spyder to run the script, but I don’t think you can install yt using spyder, so you must have used “pip install yt” to install it, or maybe you installed it from source. Do you remember how you did it?
Also, is this Linux or Mac OS X?
Best,
John

I am sorry for the late reply.
I use spyder which comes with modules installed.
Thank you for your help!

Alex,
My apologies—this is a bug in the code. I have a fix, which I hope to have ready by tonight or tomorrow.
Just a quick question—how did you install yt? It looks like your Python stack is in /usr/local.
Best,
John

I am using spyder to run the script. Spyder is using the 1.8.2 version.

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?
Best,
John

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:
File "/usr/local/lib/python2.7/dist-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 685, in runfile

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
Alex
