Hey Matt, I am pretty sure that I have tested the theano Op separately from Sympy, but again, I am probably missing something silly. After running the test cases, or evaluating k = TestInterpOp() k.CreateSuite() from the SymPy_Theano_KGM_indep.py file, one can run the following lines
In [2]: s,K,Kp = k.SymInterp() In [3]: op = k.TheanoInterpOp() In [4]: x = theano.tensor.dvector() In [5]: f = theano.function([x],op(x)) In [6]: s(4.0) Out[6]: array(16.0) In [7]: f([4.0]) Out[7]: array([ 16.]) where 's' is the sympy wrapped spline function (undefined function) and 'f' is the theano.function of the theano op created around the spline. Is this what you mean?
