Hi YT user, I'm new using YT, and I'm already having problems when I've tried to use the HOP, when I write the commands in Python, this comes out: line 1821, in __init__ self._mpi_allsum((self._data_source["ParticleMassMsun"][select]).sum(dtype='float64')) File "/usr/local/yt-unknown/src/yt-hg/yt/data_objects/data_containers.py", line 279, in __getitem__ self.get_data(key) File "/usr/local/yt-unknown/src/yt-hg/yt/data_objects/data_containers.py", line 1918, in get_data self.particles.get_data(field) File "/usr/local/yt-unknown/src/yt-hg/yt/data_objects/particle_io.py", line 92, in get_data conv_factors) File "/usr/local/yt-unknown/src/yt-hg/yt/frontends/enzo/io.py", line 154, in _read_particles filenames, ids, conv_factors = zip(*sorted(zip(filenames, ids, conv_factors))) ValueError: need more than 0 values to unpack Does anyone know how to fix this trouble? Thanks in advance, Miguel Gonzalez.
Hi Miguel, It looks to me like the halo finder is failing because it cannot find any particles. If you do: print pf.get_parameter('NumberOfParticles') what does is show? Britton 2011/7/22 Miguel Angel González <miguelglezbol@gmail.com>
