New issue 1069: Data objects used to create a profile in a for loop get garbage collected https://bitbucket.org/yt_analysis/yt/issues/1069/data-objects-used-to-create... Nathan Goldbaum: Illustrated by a test script Mateusz Ruszkowski reported on the mailing list: ``` #!python import yt profiles = [] labels = [] for i in range(0,2,1): print i ds = yt.load("Sedov_3D/sedov_hdf5_chk_%04i" % i) my_data = ds.sphere(ds.domain_center, 1.0) sim_time = ds.current_time profiles.append(yt.create_profile(my_data, "radius", fields=["density"], weight_field="cell_volume", n_bins=32)) labels.append("t= %.0f" % sim_time) plot = yt.ProfilePlot.from_profiles(profiles, labels=labels) plot.set_xlim([0.1, 1.0]) plot.save() ``` This uses the Sedov3D test dataset on yt-project.org/data.
