Hi all,
When I start up a clean version of sage 3.4 on my local machine and
enter the following into a notebook cell:
M=load('http://www.math.upenn.edu/~jbandlow/sage_data/dic_of_kst_to_G_cob_mats.sobj')
# This object is a dictionary
key = (1, Partition([1]),Partition([2]))
print key in M.keys()
M[key]
I get the following (correct) output:
Attempting to load remote file:
http://www.math.upenn.edu/~jbandlow/sage_data/dic_of_kst_to_G_cob_mats.s\
obj
Loading: [..........]
True
# A matrix that I won't reproduce here
When I enter the exact same text in a notebook cell on sagenb, I get the
following output:
Attempting to load remote file:
http://www.math.upenn.edu/~jbandlow/sage_data/dic_of_kst_to_G_cob_mats.s\
obj
Loading: [..........]
True
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/home/sage/sagenb/sage_notebook/worksheets/jbandlow/11/code/41.py",
line 10, in <module>
M[key]
File
"/home/sage/sage_install/sage-a/local/lib/python2.5/site-packages/SQLAlchemy-0.4.6-py2.5.egg/",
line 1, in <module>
KeyError: (1, [1], [2])
Why am I getting a KeyError if key in M.keys() is returning True? And
why is the behavior on sagenb different than on my local, 3.4
built-from-source on Ubuntu 10.8 distribution?
Any ideas are very welcome!
Cheers,
Jason
