convert python ndarray to theano tensor type variable

问题:

I have ndarray like :

diag = [] diag.append(np.diag([1,1,0])) diag.append(np.diag([0,1,1])) diag   [array([[1, 0, 0],    [0, 1, 0],    [0, 0, 0]]), array([[0, 0, 0],    [0, 1, 0],    [0, 0, 1]])] 

How can I convert it into Theano tensor variable of type float 64, matrix ? As I need to perform dot operation like

Theano.dot(diag, X) where X is shared variable of type float 64, matrix. 

回答1:

Just create a SharedVariable like this

diag_ = theano.shared(np.array(diag).astype("float64")) theano.dot(diag_, X)
