Problem when run yt dev in parallel on Blue Waters
by Pengfei Chen
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

getting abundance of elements contained within a sphere through Profile1D funcion
by tazkera haque
Hi,
I am trying to find abundance of C contained within a sphere through the
Profile1D function in yt. I tried something like this:
*ds=yt.load(filename)*
* sp = ds.sphere("max", (10.0, 'kpc'))*
* profile = yt.Profile1D(sp, "x", 32, rmin, rmax, False, weight_field=None)*
* profile.add_fields(["cell_mass"])*
* profile.add_fields(["c12 "])*
* profile.add_fields(["x"])*
*print profile ["cell_mass"].sum()/Msun*
*print profile ["c12 "]*["cell_mass"].sum()/Msun*
and got the following error:
* File "profile_1D.py", line 74, in <module>*
* print profile ((["c12 "]*["cell_mass"]).sum())/Msun*
*TypeError: can't multiply sequence by non-int of type 'list'*
*is there any way I can calculate the C12 abundance here?*
*Best*

Trouble installing yt

I am very new to yt and am having trouble installing it. I am running on a

$ cd yt
$ chmod +x ./doc/install_script.sh
$ ./doc/install_script.sh
After sometime installing... I get this:

Error: Particle Bounds
by Adrianna Perez
To whom it may concern,
I am having trouble loading GIZMO data to make a simple slice plot and this
is the error I get:
yt.utilities.exceptions.YTDomainOverflow: Particle bounds (-934.41559,
-727.99188, -1092.047) and (509.55978, 797.46954, 1034.1028) exceed domain
bounds [ 0. 0. 0.] code_length and [ 10000. 10000. 10000.] code_length
Any help would be really useful. Please send me any questions you may have.
Please and thank you,

Reviewing pull requests
by Stephanie Tonnesen
Hi yt-users,
So I am using the developers yt-conda version of yt. I am trying to review
a pull request, but have no idea what I am doing. All I ever do is
yt update
I literally just broke yt 5 days ago, so I am a bit unwilling to just poke
around trying out random hg commands to see what happens. Is this what I
am supposed to do once I have activated yt?
hg clone https://bitbucket.org/yt_analysis/ytcd yt
hg update yt
python setup.py install --user --prefix=
And *if* this is right, how do I grab a specific change set?
Thanks so much!
Stephanie

Projection disagrees with original data.
by Hansheng Chen
Hello yt users,
I have a question about projection. I used ds.proj() and to_frb() to get an
image array of the projected 'Electron_Density' of an entire dataset. I
multiplied the mean of projected 'Electron_Density' by the entire area of
x-y plane and got a sum of total mass of electrons. Then, I used
ds.all_data() and mean() to get the mean of 'Electron_Density' in
3-dimensional. I multiplied the mean by the volume of the entire box of the
dataset and got another sum of total mass of electrons. However, this sum
did not match the sum I got from the projected 'Electron_Density'
previously. Here are the codes I used:
import yt
import numpy as np
ds = yt.load("redshift0100/redshift0100")
print("Redshift =", ds.current_redshift)
p = yt.ProjectionPlot(ds, 2, 'Electron_Density')
density_image = p.frb['Electron_Density']
ed = density_image['Electron_Density'].convert_to_cgs()
ed_ndarr = ed.to_ndarray()
sum1 = ed_ndarr.mean() * ((105.82 * 3.085677581e+24)**2)
print(sum1)
dd = ds.all_data()
ed_3d = dd['Electron_Density'].convert_to_cgs()
sum2 = ed_3d.mean() * ((105.82 * 3.085677581e+24)**3)
print(sum2)
(105.82 * 3.085677581e+24) is the width of entire box in cm. I think sum1
and sum2 should be close to each other, but the result was that the two
values did not match with each other. Is there any problem in the codes I
used to get the values of sum1 and sum2? Could some one give me some help?
Thank you very much!
Sincerely,
Hansheng

creating gradient of a field as a derived field
by turhan nasri
Hi yt people,
I need a little help creating a derived field which will return me the
negative gradient of gravitational potential
*@derived_field(name = "gradient_gravpot", units = " cm/s**2")*
*def _gradient (field, data):*
* G = add_gradient_fields(("gas"," gravitational_potental"))*
* return (- data["gravitational_potential_gradient_x"])*
and I got this error
*NameError: global name 'add_gradient_fields' is not defined*
please suggest the right method to define the field. thanks
Best

editing yt source code
by Stephanie Tonnesen
Hi yt-ers,
I am trying to make a quick edit to the source code to see if it works, and
don't know how to actually implement the changes. Can I just make clean
and then re-make yt in my yt directory? I basically have no idea what I am
doing here...
Thanks for all advice!

Updated yt dev and now have strange plotting error
by Stephanie Tonnesen
Hi yt-users,
I just updated my yt dev and suddenly my plotting scripts don't work. When
I actually try and save my plot, I am told that I don't have "classic"
style available. I am not sure where this problem is coming from, does
anyone have some advice for me?
The code commands:
ds =
yt.load("/data001/stonnes/MWtype_BPtest/DD"+loop[i]+"/DDMWtestf"+loop[i])
ds.add_field(('gas','tracer'),function=tfrac)
logs = {('index','cylindrical_r'):False}
logs = {('gas','velocity_z'):False}
logs = {('gas','velocity_x'):False}
logs = {('gas','velocity_y'):False}
logs = {('gas','tracer'):False}
ds.index
ds.field_info['gas','velocity_z'].take_log = False
ds.field_info['gas','velocity_x'].take_log = False
plot6p = yt.ProjectionPlot(ds,"z","density")
plot6p.save()
The error message:
