[theano-users] function output cumsum() vs cumsum() function output

2018-10-03 Thread DL_user
Got another question that can't find guidelines from Theano document. Consider these two cases: Case 1: a = T.dmatrix('a') b = T.dmatrix('b') c = T.dmatrix('c') y = T.pow(a,b)-c f = theano.function([a,b,c], y) f(np.reshape(np.ogrid[0:1:4j],(2,2)),np.reshape(np.ogrid[0:1:4j],(2,2)),

[theano-users] Theano dot function has different output than Numpy's

2018-10-02 Thread DL_user
Why do these two functions have different outputs, even both of them defined from numpy's dot() function: x = T.dmatrix('x') y = T.dvector('y') z = np.dot(x,y) f = theano.function([x,y],z) f([[1,2,3],[4,5,6]],[7,8,9]) Out[31]: array([[ 7., 16., 27.], [28., 40., 54.]])
