Did you remember to recompile yt? Doing $ python setup.py develop in the root of the repository should do the trick. I'm not sure which revision 13651 corresponds to (revision numbers are not shared between mercurial repositories, only commit hashes are), but if you ended up on yt 3.0 and wanted to switch back to 2.x, you can do: $ hg update yt-2.x $ python setup.py develop to go back to the most up-to-date version of the 2.x branch.

Hi all,

I was using YT when some error messages appeared; since this happened immediately after I updated yt, I tried to "hg update 13651" to an earlier version.

It turned out to be a big mistake -- suddenly every command I tried (yt; yt update; hg update; and yt notebook) gave the following error: ======================================= Traceback (most recent call last): File "/home/hao/projects/yt/bin/yt", line 9, in <module> load_entry_point('yt==3.0dev', 'console_scripts', 'yt')() File "/home/hao/projects/yt/lib/python2.7/site-packages/distribute-0.6.32-py2.7.egg/pkg_resources.py", line 337, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/home/hao/projects/yt/lib/python2.7/site-packages/distribute-0.6.32-py2.7.egg/pkg_resources.py", line 2311, in load_entry_point return ep.load() File "/home/hao/projects/yt/lib/python2.7/site-packages/distribute-0.6.32-py2.7.egg/pkg_resources.py", line 2017, in load entry = __import__(self.module_name, globals(),globals(), ['__name__']) File "/home/hao/projects/yt/src/yt-hg/yt/utilities/command_line.py", line 19, in <module> from yt.mods import * File "/home/hao/projects/yt/src/yt-hg/yt/mods.py", line 50, in <module> from yt.data_objects.api import \ File "/home/hao/projects/yt/src/yt-hg/yt/data_objects/api.py", line 13, in <module> from grid_patch import \ File "/home/hao/projects/yt/src/yt-hg/yt/data_objects/grid_patch.py", line 25, in <module> from yt.data_objects.data_containers import YTFieldData File "/home/hao/projects/yt/src/yt-hg/yt/data_objects/data_containers.py", line 31, in <module> from yt.data_objects.derived_quantities import GridChildMaskWrapper File "/home/hao/projects/yt/src/yt-hg/yt/data_objects/derived_quantities.py", line 26, in <module> from yt.utilities.parallel_tools.parallel_analysis_interface import \ File "/home/hao/projects/yt/src/yt-hg/yt/utilities/parallel_tools/parallel_analysis_interface.py", line 29, in <module> from yt.utilities.lib import \ File "/home/hao/projects/yt/src/yt-hg/yt/utilities/lib/__init__.py", line 21, in <module> from .geometry_utils import * File "geometry_utils.pyx", line 22, in init yt.utilities.lib.geometry_utils (yt/utilities/lib/geometry_utils.c:10907) ImportError: cannot import name YTDomainOverflow ======================================== Anything to do to fix the damage besides a reinstallation?

Thanks!
