Hi all,
I'm running into an issue with translation dictionaries for the GDF
frontend.
On the tip, if I load up a gdf dataset, and do:
pf.h.find_max('Density')
I get:
http://paste.yt-project.org/show/2008/
If I instead do pf.h.find_max('density'), I get what looks like the same
error.
If I replace line 56 in yt/frontends/gdf/fields.py
55 KnownGDFFields = FieldInfoContainer()
56 add_gdf_field = KnownGDFFields.add_field
with
57 add_gdf_field = GDFFieldInfo.add_field
It works fine.
Alternatively, if I replace
96 for f,v in log_translation_dict.items():
97 add_field(f, function=TranslationFunc(v), take_log=True)
98
99 for f,v in translation_dict.items():
100 add_field(f, function=TranslationFunc(v), take_log=False)
with
102 def _generate_translation(mine, theirs, take_log=False):
103 add_field(theirs, function=lambda a, b: b[mine], take_log=take_log)
104
105
106 for f,v in log_translation_dict.items():
107 if v not in GDFFieldInfo:
108 add_field(v, function=lambda a,b: None, take_log=True,
109 validators = [ValidateDataField(v)])
110 #print "Setting up translator from %s to %s" % (v, f)
111 _generate_translation(v, f, take_log=True)
112
113
114 for f,v in translation_dict.items():
115 if v not in GDFFieldInfo:
116 add_field(v, function=lambda a,b: None, take_log=False,
117 validators = [ValidateDataField(v)])
118 #print "Setting up translator from %s to %s" % (v, f)
119 _generate_translation(v, f, take_log=False)
as is done in the orion reader, it works fine.
Anyways, if someone sees what is going on here, let me know. I'll also be
on IRC for a bit longer tonight and all tomorrow.
Thanks,
Sam
