New issue 766: Import of particle_trajectories fails in yt-2.6.1 (conda install) https://bitbucket.org/yt_analysis/yt/issue/766/import-of-particle_trajectori...
Devin Silvia:
When attempting:
from yt.analysis_modules.api import AbsorptionSpectrum
I got an important error (unrelated to the spectrum stuff) on particle_trajectories:
http://paste.yt-project.org/show/4246/
Importing directly from absorption_spectrum gets around this, but still alerting the community that particle_trajectories seems to have an issue.
