Hi all,
I'm getting the following error while installing yt-3.2.1 latest release.
Any idea what is going on here?
thanks in advance,
cheers

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
Dear colleagues,
We are very pleased to inform you that applications are now open for
the Python in Astronomy 2016 conference:
Python in Astronomy
University of Washington eScience Institute
Seattle, WA, USA
21-25th March 2016
http://python-in-astronomy.github.io/2016/
This meeting aims to bring together researchers, Python developers,
users, and educators, and will include presentations, tutorials,
unconference sessions, and coding sprints.
In addition to sharing information about state-of-the-art Python
Astronomy packages, the workshop will also focus on improving
interoperability between astronomical Python packages, providing
training for new contributors, and developing educational materials
for Python in Astronomy. The meeting is therefore aimed not only at
current developers, but also users and educators who are interested in
being involved in these efforts.
Note that this meeting is not intended to be a Python 'boot camp', and
we do expect participants to have already at least used Python for
some of their projects, even if only at a beginner level.
To apply, please go to the following page:
http://python-in-astronomy.github.io/2016/
and follow the link to the application form. Applications should be
submitted by 9th October 2015 at the latest, and we hope to let you
know by mid- to late November whether you have been accepted.
Contingent on sponsorship, we hope to offer financial support for
travel for a few participants. If you would like to apply for
financial support, please indicate this in the last section of the
application form.
Please forward this email to anyone who may be interested!

Hello again John! I'm not sure what you mean with changing the number of
chunks in the .yt/config file? I did change the number of chunks and
lowered the exposition time to get one photon list, but is that list
enough? Don't I need to merge it with another observation? Or you meant
changing the photon_per_chunk parameter somewhere else in the yt code?
Or perhaps you meant I should try the first option (run it in a machine
with more RAM / parallel)? I'll try that right now anyway! Thanks for
everything, I'll keep an eye on the patch! Barbara
------------------------------------------------------------------------
Hi Barbara, Any chance you could try the option I mentioned where you
change number of chunks in the .yt/config file? That way you might be
able to avoid doing merging altogether.
This is a bug I fixed yesterday?when I have some way of getting the patch to you I will let you know.
This happens when you choose parameters for project_photons that would result in a higher number of photons being drawn than exist in the original set that you generated. I?m going to change this error message so it?s more informative.
Best,
John
Hi Nathan,
Thanks very much for the detailed response. I had no idea that ds.index
contains so much information. I've looked at the grid data for a
simulation I did and it's quite revealing. Unfortunately for my case, a 2D
simulation, it seems that ds.index.get_smallest_dx() includes the third
(unused) dimension, which for some reason is given a (very small) thickness
in FLASH data. As a result, I get that very small dimension from
ds.index.get_smallest_dx(). Nevertheless, it seems that it should possible
to get the smallest grid dimension in each direction via the use of
ds.index.grids.RightEdge
and ds.index.grids.LeftEdge. I'm working on it now.
Regards,
Jon

Dear YT users,
I have yt installed with pip, and it reports being version 3.1. However I'd
like to use the new particle plot function, so I tried updating it with
sudo pip install -U yt
and got the error:
Downloading/unpacking yt from
https://pypi.python.org/packages/source/y/yt/yt-3.2.1.tar.gz#md5=5cda4af0...
Downloading from URL
https://pypi.python.org/packages/source/y/yt/yt-3.2.1.tar.gz#md5=5cda4af0...
Running setup.py (path:/tmp/pip_build_root/yt/setup.py) egg_info for
package yt
Cython is a build-time requirement for the source tree of yt.
Please either install yt from a provided, release tarball, or install
Cython (version 0.22 or higher).
You may be able to accomplish this by typing: pip install -U Cython
So I did this. Then I checked Cython with cython --version, it reports
version 0.23.2,
but the same yt install error remains when I attempt an update. I'm
guessing there is something I need to refresh, but I'm unsure of how to do
this.
Thanks for the assistance,
Josh

Hi all,
I've been doing FLASH runs in 2D and using yt to manipulate the data for
display -- that is, I've been creating frb objects from slices (which are
not really slices since the data is 2D anyways). One thing that bothers me
about this is the need to specify the dimensions of the frb. For some
reason 800 x 800 seems to be preferred in the yt docs, but it seems to me
that there are certain optimal dimensions that depend on the grid
structure. For example an frb that uses pixels the size of the smallest
resolution element/cell or some integer multiple of that (of course less
refined cells would be split into multiple pixels). How would one find
what that grid size would be? I guess what I'd need to know is the
dimensions of that most refined cell in the computational grid. How does
one access the grid structure information in a dataset?

Hello yt users,
I'm working with Daniel Schwen of the MOOSE team to install yt from source.
He is running OS X Yosemite, and trying to install yt over a miniconda
python. After cloning my yt repository, the install script fails with the
attached traceback. Does anyone have any ideas?
Thanks,
Andrew

Hi all,
I wanted to bring to your attention a change in the SPH smoothing
kernel behavior. This has landed on the development version on yt,
but *not* the stable, and will not be backported to stable until the
next major release (3.3).
Previously, a kernel normalization was applied to smoothed grid cells.
This could result in mass conservation not being 100% preserved; some
cases were worse than others. (Cosmology was typically fine.) The
recent change has removed the normalization step.
Here are some relevant PRs:
