URL: https://github.com/apache/tvm/issues/14877

   Each item in the features array in the auto_scheduler consists of some 
number of arrays of length 164. This number is not fixed and can be from 1 to 
8. For each of this items (consisting of multiple features vectors) there is 
one target value.

   But for the loss function it uses the sum of 
(f(x[i][1])+f(x[i][2])+…+f(x[i][len_i])-y[i])^2 for all i. Here f is our model, 
x[i][1], x[i][2], …, x[i][len_i] are vectors of features of object i, y[i] its 
target value of object i. So we sum the predictions for all feature vectors of 
the object and we want it to be close to the target value.

   Why we have the sum of the predictions in the loss function, but not mean 
value of them?
