[yt-users] Error with important of AbsorptionSpectrum

[Devin Silvia]

Hi all,

I recently used conda to install yt, but when I try to import
AbsorptionSpectrum, I get this error:

http://paste.yt-project.org/show/4246/

I'm not familiar with particle_trajectories, but is this something
that is actually needed by AbsorptionSpectrum?  If not, should it even
being trying to import that?  Any thoughts/help are, as always,
appreciated.

Cheers,
Devin
