Hey everyone: I just pulled the newest version of yt and installed it on kraken. It installed OK (installing locally HDF5, zlib, libpng and python). I remembered to swap the PGI modules to the GNU modules. Unfortunately, when I go to run it I get the following error involving "FLASHFields": $ yt Traceback (most recent call last): File "/nics/b/home/chummels/source/yt-x86_64/bin//yt", line 9, in <module> load_entry_point('yt==2.0dev', 'console_scripts', 'yt')() File "/nics/b/home/chummels/source/yt-x86_64/lib/python2.6/site-packages/distribute-0.6.10-py2.6.egg/pkg_resources.py", line 299, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/nics/b/home/chummels/source/yt-x86_64/lib/python2.6/site-packages/distribute-0.6.10-py2.6.egg/pkg_resources.py", line 2229, in load_entry_point return ep.load() File "/nics/b/home/chummels/source/yt-x86_64/lib/python2.6/site-packages/distribute-0.6.10-py2.6.egg/pkg_resources.py", line 1948, in load entry = __import__(self.module_name, globals(),globals(), ['__name__']) File "/nics/b/home/chummels/source/yt/yt/command_line.py", line 26, in <module> from yt.mods import * File "/nics/b/home/chummels/source/yt/yt/mods.py", line 32, in <module> import yt.lagos as lagos File "/nics/b/home/chummels/source/yt/yt/lagos/__init__.py", line 79, in <module> from FLASHFields import * ImportError: No module named FLASHFields I've never seen this error, and I investigated a bit but couldn't find much about it. Any ideas from people? What is this mysterious FLASHFields module? Cameron
