[yt-users] Loading particles

[Ariadna Murguia]

Dear Nathan,

What I mean is that the loading part doesn't finish, attached is the error file.

Thanks!

Ariadna

Dear yt users,


Hi Ariadna,


I'm trying to load a set of particles (a bunch of particles, so I'm running it in the hyades cluster). I have their positions and velocities. What I'm doing is just defining a box as the domain of my simulation, the data as a dictionary of velocities and positions, and just saying yt.load_particles(data=data, bbox=bbox). I tried it for some particle files that I'm using, and it works, but for others, it crashes. I'm getting the following error:


/pfs/sw/python/yt/yt-x86_64/src/yt-hg/yt/units/yt_array.py:793: RuntimeWarning: invalid value encountered in divide  return YTArray(super(YTArray, self).__div__(ro))

/pfs/sw/python/yt/yt-x86_64/src/yt-hg/yt/utilities/math_utils.py:861: RuntimeWarning: invalid value encountered in arccos  return np.arccos( JdotCoords / np.sqrt(np.sum(coords**2,axis=0)) )


These are just warnings, which might indicate that something is going wrong but also might not.

When you say it crashes, how does it crash? Does it print any error message or traceback? If so, can you share those?


I tried it in my computer with less particles,and it works perfectly. Am I loading the particles wrong or is there a way to fix this error?

Thank you very much in advance


All the best,

Ariadna
