Comment (by strogdon):
Here is some background on the failing test
{{{
sage -t -long -force_lib "devel/sage-main/sage/plot/matrix_plot.py"
}}}
that's mentioned above
[http://trac.sagemath.org/sage_trac/ticket/11334#comment:56 above]. The
failure in Sage of
{{{
sage: matrix_plot([[sin(x), cos(x)], [1, 0]])
}}}
seems to be associated with the following sequence
{{{
sage: import numpy as np
sage: np.asarray([[sin(x), cos(x)], [1, 0]], dtype = float)
}}}
With numpy-1.5.1 I get
{{{
sage: np.asarray([[sin(x), cos(x)], [1, 0]], dtype = float)
---------------------------------------------------------------------------
ValueError Traceback (most recent call
last)
/storage/sage/sage-5.5.rc0/<ipython console> in <module>()
/storage/sage/sage-5.5.rc0/local/lib/python2.7/site-
packages/numpy/core/numeric.py in asarray(a, dtype, order)
282
283 """
--> 284 return array(a, dtype, copy=False, order=order)
285
286 def asanyarray(a, dtype=None, order=None):
ValueError: setting an array element with a sequence.
}}}
and with numpy-1.7.0b2
{{{
sage: np.asarray([[sin(x), cos(x)], [1, 0]], dtype = float)
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
/storage/sage/sage-5.5.rc0/<ipython console> in <module>()
/storage/sage/sage-5.5.rc0/local/lib/python2.7/site-
packages/numpy/core/numeric.pyc in asarray(a, dtype, order)
318
319 """
--> 320 return array(a, dtype, copy=False, order=order)
321
322 def asanyarray(a, dtype=None, order=None):
/storage/sage/sage-5.5.rc0/local/lib/python2.7/site-
packages/sage/symbolic/expression.so in
sage.symbolic.expression.Expression.__float__
(sage/symbolic/expression.cpp:7023)()
TypeError: unable to simplify to float approximation
}}}
So it would appear that the ValueError when using numpy-1.5.1 is thrown my
numpy but the TypeError when using numpy-1.7.0b2 is thrown by Sage.
