When I used the fc.py to train the MINIST,it happened a error: File "D:\pycharm\project\fc.py", line 107, in calc_gradient ) * (label - self.layers[-1].output) ValueError: operands could not be broadcast together with shapes (10,) (10,300)

I found that if the label is (10,1) can do subtraction

function backward should be modified: self.W_grad = np.array(mat(delta_array).T * mat(self.input))

I suggest you change the list format of the data（train and test） to an array type. np.array(data)
