Compilation problem

Feb. 25, 2016

Hi yt Users, I’m having a problem compiling the current development branch of yt on NASA pleiades, and I’m hoping that someone can suggest what could be going wrong. Here’s what I get when I try to compile: bridge4:yt mkrumhol$ /nasa/python/2.7.9/bin/python setup.py develop --prefix=/u/mkrumhol running develop running egg_info writing requirements to yt.egg-info/requires.txt writing yt.egg-info/PKG-INFO writing top-level names to yt.egg-info/top_level.txt writing dependency_links to yt.egg-info/dependency_links.txt writing entry points to yt.egg-info/entry_points.txt reading manifest file 'yt.egg-info/SOURCES.txt' reading manifest template 'MANIFEST.in' warning: no previously-included files found matching 'scripts/pr_backport.py' no previously-included directories found matching 'doc/source/reference/api/generated' no previously-included directories found matching 'doc/build' writing manifest file 'yt.egg-info/SOURCES.txt' running build_ext pyrexc yt/analysis_modules/photon_simulator/utils.pyx --> yt/analysis_modules/photon_simulator/utils.c /home3/mkrumhol/yt/yt/analysis_modules/photon_simulator/utils.pyx:6:17: Syntax error in C variable declaration building 'yt.analysis_modules.photon_simulator.utils' extension gcc -fno-strict-aliasing -O2 -Wno-error -pipe -DHAVE_DB_185_H -pthread -I/usr/include -I/nasa/pkgsrc/2014Q4/include/db4 -I/nasa/pkgsrc/2014Q4/include -DNDEBUG -O2 -Wno-error -pipe -DHAVE_DB_185_H -pthread -I/usr/include -I/nasa/pkgsrc/2014Q4/include/db4 -I/nasa/pkgsrc/2014Q4/include -fPIC -I/nasa/pkgsrc/2014Q4/include/python2.7 -I/nasa/pkgsrc/2014Q4/lib/python2.7/site-packages/numpy/core/include -c yt/analysis_modules/photon_simulator/utils.c -o build/temp.linux-x86_64-2.7/yt/analysis_modules/photon_simulator/utils.o gcc: yt/analysis_modules/photon_simulator/utils.c: No such file or directory gcc: no input files error: command 'gcc' failed with exit status 1 I’m using python 2.7.9 and cython 0.23.4.

Pyx + Tex
by John Regan Feb. 24, 2016

Feb. 24, 2016

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. yt : [INFO ] 2015-11-25 14:51:23,198 xlim = 0.456408 0.541884 yt : [INFO ] 2015-11-25 14:51:23,198 ylim = 0.482775 0.568251 yt : [INFO ] 2015-11-25 14:51:23,200 Making a fixed resolution buffer of (('gas', 'H_number_density')) 800 by 800 Create Multiplot.... yt : [WARNING ] 2015-11-25 14:51:24,085 No field specified.

EnzoDatasetInMemory not working in parallel
by Britton Smith Feb. 24, 2016

Feb. 24, 2016

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

working with general hdf5 data from galaxy simulations
by D Mick Feb. 24, 2016

Feb. 24, 2016

Hello all, yt has some of the greatest plotting capabilities, and I greatly enjoy working with yt! Recently I have begun to work with hdf5 data from a large scale galaxy simulation (illustris) and I was wondering how I can work with the data, is there a general munging procedure for getting it into the correct yt format? When I try to plot import yt ds = yt.load("Groups_hdf5_plt_cnt_0150") yt.SlicePlot(ds, 'x', "density", width = (800.0, 'kpc')).save() yt.SlicePlot(ds, 'y', "density", width = (800.0, 'kpc')).save() yt.SlicePlot(ds, 'z', "density", width = (800.0, 'kpc')).save() I get the following error: /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/yt/frontends/gadget_fof/data_structures.pyc in _parse_parameter_file(self) * 151* self.periodicity = (True, True, True) * 152* self.current_redshift = hvals["Redshift"] --> 153 self.omega_lambda = hvals["OmegaLambda"] * 154* self.omega_matter = hvals["Omega0"] * 155* self.hubble_constant = hvals["HubbleParam"] KeyError: 'OmegaLambda' I am guessing this is because the field entries do not match up. Any help is much appreciated! Dan

How to make a projection plot of a desirable thickness?
by Reju Sam John Feb. 23, 2016

Feb. 23, 2016

Hi, I would like to make a projection of a field along 'z' axis centered at [0.5, 0.5, 0.5] with a thickness of 10Mpc (5 Mpc to +z dir and 5 Mpc to -z dir). How to select the above-mentioned region from the whole simulation volume? I am using YT Legacy 2.x. Thank you. -- Reju Sam John

Google summer of code ideas for yt
by Nathan Goldbaum Feb. 19, 2016

Feb. 19, 2016

Hi all, This year yt is applying with the OpenAstronomy organization to participate in Google Summer of Code. The ideas we've put forward are here (scroll down the page a bit): http://openastronomy.org/gsoc/gsoc2016/ideas.html#yt If you know any students (undergrad, grad) who might be interested in getting paid by Google to work on yt over the summer, please forward them this message. I'm happy to answer questions about this here or off list. -Nathan

yt-2.x installation problem on Mac 10.11
by Pengfei Chen Feb. 18, 2016

Feb. 18, 2016

Hi all, I'm trying to install yt-2.x on my Mac 10.11. I could use get_yt.sh to install yt-2.x. But I need to add "--enable-shared" while installing python, so that I could use inline python later on with yt. Is there a way that I could modify get_yt.sh to add the option "--enable-shared" while installing python? I also tried to install yt-2.x with install_script.sh, but I got the following error: Installing Python. This may take a while, but don't worry. yt loves you. ******************************************** FAILURE REPORT: ******************************************** -d /Users/madcpf/Documents/shared_yt2/lib/python2.7 -f \ -x 'bad_coding|badsyntax|site-packages|lib2to3/tests/data' \ /Users/madcpf/Documents/shared_yt2/lib/python2.7 Traceback (most recent call last): File "/Users/madcpf/Documents/shared_yt2/lib/python2.7/compileall.py", line 16, in <module> import struct File "/Users/madcpf/Documents/shared_yt2/lib/python2.7/struct.py", line 1, in <module> from _struct import * ImportError: No module named _struct make: *** [libinstall] Error 1 ******************************************** ******************************************** Failure.

Feb. 17, 2016

Hello all, I am trying to install yt on Mac 10.11.2. My most current efforts use ³yt² branch, and I am trying to install from the install_script.sh. We have modified the python installation section of the script from: ./configure --prefix=${DEST_DIR}/ ${PYCONF_ARGS} To: ./configure CPPFLAGS=-I/usr/local/opt/openssl/include --enable-shared --prefix=${DEST_DIR}/ ${PYCONF_ARGS} I have also added : export LD_LIBRARY_PATH=/usr/local/opt/openssl/lib:$LD_LIBRARY_PATH I have used: Brew install openssl Brew link force openssl My installation fails with: ******************************************** FAILURE REPORT: ******************************************** checking size of int... 0 checking size of long... 0 checking size of void *... 0 checking size of short... 0 checking size of float... 0 checking size of double... 0 checking size of fpos_t... 0 checking size of size_t... configure: error: in `/Users/Azton/Research/yt/src/Python-2.7.9': configure: error: cannot compute sizeof (size_t) See `config.log' for more details Using the get_yt.sh script that uses miniconda works, but I don¹t know if the ³conda install python² command will include ³--enable-shared² My question is two part: Does anyone have an idea for using the install_script.sh? (2) Failing using the install_script, would using the get_yt.sh install python with enable-shared? Thanks for any help, Azton
