auto srcdata = score.accessor<float,3>();
cout << srcdata[0][0][0] << endl;
for (int i = 0; i < srcdata.size(0); i++) {
	int max_index = 0;
	float max_value = -1000;
	for (int j = 0; j < srcdata.size(1); j++) {
		
		for (int k =0;k< srcdata.size(2);k++)
		{
			cout << "maxvalue:" << srcdata[i][j][k] << endl;
			if (srcdata[i][j][k] > max_value) {
				max_value = srcdata[i][j][k];
				max_index = k;
			}

		}

i use accessor as above:but i can not  get the value by cout <<srcdata[i][j][k
