Can't find linalg_lu_factor functions

In the c++ documentation there are many alternatives for lu factorizations. However, the only lu factorization function I can find in my project is at::_lu_with_info. Maybe there is some extra header I have to include. I have looked inside /include/ATen/Functions.h and the only function I find there is again at::_lu_with_info. Im looking specifically for linalg_lu_factor_ex_out, but all similar functions are also gone. I downloaded 1.10.2 with cuda 11.3
