possible.


If "magma" is set then MAGMA will be used wherever possible.


If "default" (the default) is set then heuristics will be used
     to pick between cuSOLVER and MAGMA if both are available.


When no input is given, this function returns the currently
     preferred library.


Note: When a library is preferred other libraries may still be used
   if the preferred library doesn't implement the operation(s) called.
   This flag may achieve better performance if PyTorch's heuristic
   library selection is incorrect for your application's inputs.
