A workaround would be to retain the ds's loaded in memory, for instance by appending them to a list or something. Not a solution, but a workaround. On Thu, Aug 20, 2015 at 6:55 PM, Nathan Goldbaum <nathan12343@gmail.com> wrote:

Hi,
I am trying to plot two profiles on one plot and adjust xlim. I am getting the following error message:
Traceback (most recent call last): File "test.py", line 17, in <module> plot.set_xlim([0.1, 1.0]) File "/home/mateuszr/my_yt/yt-x86_64/src/yt-hg/yt/visualization/plot_container.py", line 62, in newfunc rv = f(*args, **kwargs) File "/home/mateuszr/my_yt/yt-x86_64/src/yt-hg/yt/visualization/profile_plotter.py", line 547, in set_xlim extrema=extrema, units=units) File "/home/mateuszr/my_yt/yt-x86_64/src/yt-hg/yt/data_objects/profiles.py", line 1436, in create_profile bin_fields = data_source._determine_fields(bin_fields) File "/home/mateuszr/my_yt/yt-x86_64/src/yt-hg/yt/data_objects/data_containers.py", line 552, in _determine_fields finfo = self.ds._get_field_info(ftype, fname) ReferenceError: weakly-referenced object no longer exists
--------------------------------------------------- I am using the following script:
import yt
profiles = [] labels = []
for i in range(0,2,1):
print i ds=yt.load("./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()
------------------------------------------------------ I am using the following yt version:
Version = 3.3-dev Changeset = 603eab147248 (yt) tip
-------------------------------------------------------
Data = standard Flash Sedov test.
Any idea what I may be doing wrong?
Thanks, Mateusz
