I tried to compille this simple code: from pylab import * from matplotlib import * import sys sys.path.insert(0, "/home/mturk/yt/yt-3.0") from yt.config import ytcfg; ytcfg["yt","loglevel"] = "20" from yt.imods import * ds = load("output_00003/info_00003.txt") print ds.parameters["nstep_coarse"], ds.parameters["levelmax"] print ds.parameters But i recieved this error message: UsageError: Invalid GUI request 'inline', valid ones are:['osx', 'qt4', 'glut', 'gtk3', 'pyglet', 'wx', 'none', 'qt', 'gtk', 'tk', None] Someone can help me?

ramses-rt data with yt
by Mike Butler 10 Apr '14

10 Apr '14

Hello, I am trying to make some projections of some Ramses-RT data and am getting strange results (see attached projection). I have tried manually specifying the fields and just doing pf=load('data') and get the same result. Everything still works fine with non-RT Ramses data. I'm not sure if it's relevant but when I do the projection I get the following messages that I haven't seen before: yt : [INFO ] 2014-04-10 14:23:17,651 Loading field plugins. yt : [INFO ] 2014-04-10 14:23:17,651 Loaded angular_momentum (8 new fields) yt : [INFO ] 2014-04-10 14:23:17,651 Loaded astro (14 new fields) yt : [INFO ] 2014-04-10 14:23:17,651 Loaded cosmology (20 new fields) yt : [INFO ] 2014-04-10 14:23:17,652 Loaded fluid (55 new fields) yt : [INFO ] 2014-04-10 14:23:17,652 Loaded fluid_vector (87 new fields) yt : [INFO ] 2014-04-10 14:23:17,653 Loaded geometric (102 new fields) yt : [INFO ] 2014-04-10 14:23:17,653 Loaded local (102 new fields) yt : [INFO ] 2014-04-10 14:23:17,653 Loaded magnetic_field (108 new fields) Any ideas? Thanks, Mike

Changes to the yt-3.0 branch
by Matthew Turk 08 Apr '14

08 Apr '14

Hi everyone, This is just a heads up that we're going to be merging the "experimental" bookmark into "development" sometime in the next few days. This means if you're using yt-3.0 and you update, your field names and whatnot will change -- but the development docs on the website cover most of this, and I think most everyone using 3.0 has been on this already. If you run into any troubles, please do write to the mailing list with questions. Thanks, Matt

Thanks Hilary! That helps a lot.

Star Speeds
by Munier Azzam Salem 08 Apr '14

08 Apr '14

Hey Guys, I'm looking to work with star particle velocities, ideally: some sort of mass-weighted-average of star particle velocities within a given cell (I'm using enzo, if that's relevant). This doesn't seem to exist in th universal field list, although the cic_particle_velocity_x<http://yt-project.org/docs/dev/reference/field_list.html?highlight=field%20…> /y/z in the enzo field list seem relevant. Any advice? thanks! Munier -- Munier A. Salem // 845.489.6450

Hi all, how would you suggest running AbsorptionSpectrum in parallel? I'm looking to make spectra for thousands of rays as efficiently as I can. Thanks! -Claire

Phase plot pixel has white outline

Hi all, Is it possible when saving phase plots in EPS format to get rid of the white outline of each pixel? When shrinking the diagram the white makes the colors look faded. From G.S.

Problem with annotate_contour() callback on OffAxisProjectionPlots
by Cameron Hummels 02 Apr '14

02 Apr '14

Hey everyone, I have an unusual problem that I cannot seem to work out. I'm trying to generate a set of contours on an OffAxisProjectionPlot using the underlying data from another OffAxisProjectionPlot (i.e. a different data_source). I can get this working A-OK when I just use the ProjectionPlot class, but when I attempt to use the OffAxisProjectionPlot, I encounter problems. I made a small script demonstrating this problem, as well as the success when this method is applied to a ProjectionPlot object. Any suggestions? Note, this is yt 2.x dev. Here is the script: http://paste.yt-project.org/show/4459/ Cameron -- Cameron Hummels Postdoctoral Researcher Steward Observatory University of Arizona http://chummels.org

data container selection by field value
by Marc Schartmann 02 Apr '14

02 Apr '14

Dear all, is it possible to create a data container in which only those cells are included in which one of the fields (e.g. the tracer field) has a value above a certain threshold? Thanks a lot in advance. Best wishes, Marc

Fwd: [IPython-dev] [ANNOUNCE] IPython 2.0.0
by Nathan Goldbaum 02 Apr '14

02 Apr '14

---------- Forwarded message ---------- From: MinRK <benjaminrk(a)gmail.com> Date: Tue, Apr 1, 2014 at 10:57 PM Subject: [IPython-dev] [ANNOUNCE] IPython 2.0.0 To: IPython Development list <ipython-dev(a)scipy.org> Cc: ipython user list <IPython-User(a)scipy.org> While April 1 may be a very loose definition of winter, IPython 2.0 is actually [out](https://pypi.python.org/pypi/ipython)! I promise this is not an April Fool's joke, but if you don't believe me just pip install --upgrade ipython to find out. See [what's new](http://ipython.org/ipython-doc/2/whatsnew/version2.0.html) for more details, but the highlights are: - interactive widgets for the notebook - directory navigation in the notebook dashboard - persistent URLs for notebooks - a new modal user interface in the notebook - a security model for notebooks You can check out the [example notebooks]( http://nbviewer.ipython.org/github/ipython/ipython/blob/master/examples/Ind…) on nbviewer, or download them and try things out yourself. This is the first IPython release with wheels (one for py2, one for py3, for now), so please give those a test if you can. These will be installed by default for anyone using current pip (1.5). We plan to have 2.0.1 within a month based on initial feedback, so bring on the bug reports! Thanks for all your support, we have a great time working on this. -IPython HQ _______________________________________________ IPython-dev mailing list IPython-dev(a)scipy.org http://mail.scipy.org/mailman/listinfo/ipython-dev
