How to compute the Shapley value of BP neural network

Hello, I trained a BP nerual network using newff function, and wanted to obtain its Shapley value. But error occurs like this:

How can I deal with it?

Can you share your code?

P = [2 3 1;3 4 5;1 3 4;4 6 7;2 7 3]';

T = [1 2 3 4 5];

net=newff(P,T,5,{'tansig' 'purelin'},'trainlm');

[net,tr]=train(net,P,T);

queryPoint = P(:,1);

explainer1 = shapley(net,P,'QueryPoint',queryPoint);
