argmax with axis return argmin in 0.24.2 if expression dimension == 1 #2550
Description
Minimal code to reproduce:
#include <iostream>
#include <xtensor/xtensor.hpp>
#include <xtensor/xsort.hpp>
int main() {
xt::xtensor<double, 1> xtest{0, 1, 2, 3, 4};
std::cout << xt::argmax(xtest)(0) << std::endl;
std::cout << xt::argmax(xtest, 0)(0) << std::endl;
return 0;
}
0.24.1 output:
4 4
0.24.2 output:
4 0
With the debugger I noticed that the compare function is ignored if dimension is 1 and an argmin implementation is called:
