Issues with the bitbucket API
by Nathan Goldbaum July 12, 2014

July 12, 2014

Hi all, There has been some lag with the bitbucket API lately. Unfortunately when Fido tries to pull changes via the API it shows no changes even if there are new changes via the web interface. Long story short, if fido says your tests fail, take a look at the console log. If it says near the bottom that there was nothing to merge in, you've hit the bitbucket API issue. Nathan

TimeSeries Objects
by Cameron Hummels July 12, 2014

July 12, 2014

Hey everyone, I just discovered by accident that one can now generate a TimeSeries DatasetSeries object with the load() command in yt-3.0. import yt time_series = yt.load('DD????/DD????') for ds in time_series: print ds.current_time I don't know when this functionality was created or by whom, but it's great and simplifies the timeseries analysis steps. Does it work for all frontends? I'm happy to update the timeseries documentation with this information, but I wanted to make sure it … [View More]

adding datasets
by Michael Zingale July 11, 2014

July 11, 2014

Hi, I'd like to add some BoxLib datasets to the suite of public datasets available for testing and experiementation. Can someone point me to the procedure of how to do that? and any guidelines regarding size. Also, are both 2- and 3-d (and 1-d?) datasets acceptable there?

Removing some analysis modules, removing yt.analysis_modules.api
by John ZuHone July 11, 2014

July 11, 2014

Hi all, I've issued a PR with some potentially controversial changes: https://bitbucket.org/yt_analysis/yt/pull-request/1009/removing-analysis-mo… which removes a few analysis modules as per this Trello card: https://trello.com/c/tJuM4kkk/23-remove-analysis-modules-as-needed Britton has also suggested that we do away with yt.analysis_modules.api entirely, as importing it imports a whole bunch of stuff you don't need, especially when you only need one module at a time (which is usually the … [View More]

SDF pull request
by Matthew Turk July 10, 2014

July 10, 2014

Hi all, Can we get some eyes on the SDF pull request? Since the that uses it went out yesterday, I was hoping to get it in, as long as we can identify any blockers that can and will be addressed before 3.0 goes out. https://bitbucket.org/yt_analysis/yt/pull-request/955/wip-sdf-frontend-and-… I think it now depends on thingking when actually being used for http SDF, but that's pure python and easy to install. -Matt

yt with python3
by Jill Naiman July 9, 2014

July 9, 2014

Hi Folks! So, I'm trying to build yt with python3. My python/c is still noobish, but so far I've converted everything with 2to3, however I'm getting some errors in regards to the kdtree libraries. I was wondering if anybody has tried a python3 build and/or if anybody has an idea on how to properly install new kdtree libraries for python3? Thanks for any insights! -Jill

Forthon 0.8.13
by Douglas Harvey Rudd July 9, 2014

July 9, 2014

Hi all, Has anyone tried to build YT using a recent version of Forthon? I've been building using 0.8.10 on an older Python installation but when I use any of 3 installations using Forthon 0.8.13 (pip installed, 0.8.15 is current) it fails due to misunderstanding how to construct the module fortran file from the module name: Traceback (most recent call last): File "/software/python-2.7-2014q2-el6-x86_64/bin/Forthon", line 2, in <module> import Forthon.Forthon_builder File "/… [View More]
