Hi all,
I have trouble running yt in parallel on Blue Waters. I installed yt using
miniconda, the version of yt is
~/miniconda/lib $yt version
yt module located at:
/u/sciteam/madcpf/miniconda/lib/python2.7/site-packages/yt-3.3.dev0-py2.7-linux-x86_64.egg
The current version and changeset for the code is:
---
Version = 3.3-dev
Changeset = 90f900be7a36+ yt
Then with miniconda/bin in PATH I installed mpi4py-2.0.0. But when I tried
to make the following simple output in parallel, I get:
import yt
yt.enable_parallelism()
from yt.utilities.parallel_tools.parallel_analysis_interface import\
parallel_objects, communication_system
comm = communication_system.communicators[-1]
print comm.rank, comm.size
0 1
0 1
0 1
0 1
0 1
0 1
0 1
0 1
...
When I run a similar code but with yt-2.x also on Blue Waters, I get what I
expect:
7 16
15 16
6 16
9 16
11 16
8 16
0 16
4 16
...
I'm confused about it. Could anyone give me some suggestions please?
Thanks,
Pengfei
Dear YT Users,
To better understand covering_grid (or smoothed_covering_grid), can someone
explain what dimensions I should use when I have multiple levels of
refinement? If I have 1 level of refinement from AMR data, the dimensions
should be the same, I believe, but what if I have 2 or 3 levels of
refinement? Should the fixed resolution region then have dimensions of
dims*2^2 and dims*3^2 respectively?
Here is one example from a tutorial
<http://yt-project.org/doc/examining/low_level_inspection.html#examining-g...>
if that helps isolate my question:
all_data_level_2 = ds.covering_grid(level=2, left_edge=[0,0.0,0.0],
dims=ds.domain_dimensions * 2**2)
Thanks in advance,
Carla
Hi all,
I'm getting the following error while installing yt-3.2.1 latest release.

Hi All,
I recently moved to working on a new machine and I've run into problems
with eps_writer and pyx and tex. It seems pyx and tex are not talking to
one another. I know pyx can sometimes have an iffy relationship with tex
but does anyone know how to make them like each other?
This is the output I get.

Hi all,
I've recently been trying to use yt's inline analysis functionality with
Enzo and am having some difficultly getting it to work in parallel. I am
using the development tip of yt. In serial, everything works fine, but in
parallel, I get the following error:
http://paste.yt-project.org/show/5694/
It seems that the issue is that yt is not correctly identifying which grids
are available on a given processory for the EnzoDatasetInMemory object.
Does anyone have an idea of how to fix this? Has anyone else seen this?
For reference, my user_script is just this:
import yt
from yt.frontends.enzo.api import EnzoDatasetInMemory
def main():
ds = EnzoDatasetInMemory()
ad = ds.all_data()
print ad.quantities.total_quantity("cell_mass")
Thanks for any help,
Britton
Hi yt user,
I make a simple DM and gas density profile for my enzo simulation with
following script:
======================
import matplotlib as matplotlib
matplotlib.use('Agg')
import yt
import yt.units as units
import numpy as np
import matplotlib.pyplot as plt
def _radiuspc(field, data):
return data[('radius')].in_units('pc')
yt.add_field('radiuspc', function=_radiuspc, units="pc")
Nbin= 100
rmax = 4000
index = 60
ds = yt.load("../DD%04d/DD%04d" % (index,index))
ds.index
ad= ds.all_data()
center = ds.find_max(("gas", "density"))[1]
my_sphere = ds.sphere(center, rmax*units.pc)
rmin = max([1.0e-4,2.0*ds.index.get_smallest_dx().in_units('pc')])
profile = yt.Profile1D(my_sphere, 'radiuspc', Nbin, x_min=rmin,
x_max=rmax, x_log=True, weight_field='cell_volume')
profile.add_fields(('gas','density'))
profile.add_fields(('gas','dark_matter_density'))
profile.add_fields(('deposit','all_density'))
plt.plot(np.log10(profile.x), np.log10(profile[('gas','density')]),
label="('gas','density')", linestyle="-", color='g')
plt.plot(np.log10(profile.x),
np.log10(profile[('gas','dark_matter_density')]),
label="('gas','dark_matter_density')", linestyle="-", color='r')
plt.plot(np.log10(profile.x),
np.log10(profile[('deposit','all_density')]),
label="('deposit','all_density')", linestyle="-", color='b')
plt.legend(loc=0,prop={'size':9})
plt.savefig('DMTest')
======================
The only particle in the simulation is the dark matter so that
profile[('gas','dark_matter_density')] and
profile[('deposit','all_density')] should be same.
However, as shown in the attached figure, they are very different.
I would like to ask a few questions regarding to this plot.
1) Why do profile[('gas','dark_matter_density')] and
profile[('deposit','all_density')] show significant difference?
2) What limit the minimum r in profile[('deposit','all_density')]?
3) If I would like to make total density profile, what do I do?
I think that profile[('deposit','all_density')] is more liable result.
Can I add data[('gas','density')] and
data[('deposit','all_density')], two different field types, in the
derived field?
Thank you in advance,
Junhwan Choi

Hi yt users,
I'm working with a particle dataset and I'm wondering if it is possible to
only load a certain type of particle fields from the snapshot as my
dataset? For example, there might be 'PartType0' and 'PartType1' in the
snapshot, but I only want to load 'PartType0'.
The reason I want to do this is that, to my understanding, the octree of
the particle dataset is constructed adaptively according to the number of
particles, including all types of particles in the dataset. But I want the
octree constructed only according to the type of particles I'm interested
in. Is it possible?
Thanks,
Bili
Hi folks,
The current default colormap that yt uses is called "Algae," and it's been
with us for a while. Recently some of us on the yt-dev mailing list (which
is open to join!) have begun to look at alternate colormaps that have
better characteristics, particularly from an accessibility perspective.
If you have the time, it would be really, *really* helpful if you could
take this anonymous, two question (only one of which is mandatory!) poll
about which of the four candidates we've come up with you like the best.
http://goo.gl/forms/D4qQqkPIMq
Thanks very much! The poll will be open at least a week, and I'll report
back the results here sometime after that.

Hi yt users,
I try to make a particle angular momentum profile using the following script:
================================
import matplotlib as matplotlib
matplotlib.use('Agg')
import yt
import yt.units as units
import numpy as np
import matplotlib.pyplot as plt
def _radiuspc(field, data):
return data[('radius')].in_units('pc')
yt.add_field('radiuspc', function=_radiuspc, units="pc")
index = 45
Nbin= 100
rmax = 3000
ds = yt.load("../DD%04d/DD%04d" % (index,index))
ds.index
ad= ds.all_data()
center = ds.find_max(("gas", "density"))[1]
rmin = max([1.0e-3,2.0*ds.index.get_smallest_dx().in_units('pc')])
sphere = ds.sphere(center, rmax*units.pc)
bulk_velocity = sphere.quantities['BulkVelocity']()
sphere.set_field_parameter('bulk_velocity', bulk_velocity)
profile = yt.Profile1D(sphere, 'radiuspc', Nbin, x_min=rmin,
x_max=rmax, x_log=True, weight_field=None)
profile.add_fields(('all', 'particle_angular_momentum_x'))
profile.add_fields(('all', 'particle_angular_momentum_y'))
profile.add_fields(('all', 'particle_angular_momentum_z'))
PartAngularMomentum = np.sqrt(profile[('all', 'particle_angular_momentum_x')]**2
+ profile[('all',
'particle_angular_momentum_y')]**2
+ profile[('all',
'particle_angular_momentum_z')]**2)
plt.plot(profile.x, PartAngularMomentum, label='Total',linestyle="-",color='r')
plt.xlabel('r [pc]')
plt.ylabel('pang')
======================================
And I got the following error:

Hi yt user,
I try to make a multi panels plot with eps_writer modules.
I use following script and it works with one unpleasant shortcoming.
==================================================
import matplotlib as matplotlib
matplotlib.use('Agg')
import numpy as np
import matplotlib.pylab as pylab
import yt
import yt.units as units
import yt.visualization.eps_writer as eps
import pyx
index = 60
ds = yt.load('../DD%04d/DD%04d' % (index,index))
ds.add_particle_filter('sink')
ad = ds.all_data()
center = ds.find_max(('gas', 'density'))[1]
# scale and limit
LBox = [4000, 4]
plot_list = []
for nrow in range(0,2):
for norm in 'zxy':
pc =yt.SlicePlot(ds, norm, ('gas', 'density'), center=center)
pc.set_width(LBox[nrow],"pc")
plot_list.append(pc)
ep = eps.multiplot(ncol=3, nrow=2, yt_plots=plot_list, bare_axes = True)
ep.title_box("xy", loc=(0.1,1.95))
ep.title_box("yz", loc=(1.1,1.95))
ep.title_box("xz", loc=(2.1,1.95))
ep.scale_line(label="%6.0f kpc" % (LBox[0]/4000.0), size=0.25,
linewidth=pyx.style.linewidth.Thick, loc=(0.05,1.08))
ep.scale_line(label="%6.0f pc" % (LBox[1]/4.0) , size=0.25,
linewidth=pyx.style.linewidth.Thick, loc=(0.05,0.08))
ep.save_fig("multi_plot")
==================================================
Here, I attach the resulting plot.
Everything is fine except there are white spacing/margin between panels.
Is there any way to remove the white spacing/margin?
Thanks in advance,
Junhwan
