is one of ('gelsd', 'gelss'), otherwise it is an empty
     tensor.
Note:
 This function computes *X = *"A"*.pinverse() @ *"B" in a faster
 and more numerically stable way than performing the computations
 separately.

Warning:
 The default value of "rcond" may change in a future PyTorch
 release. It is therefore recommended to use a fixed value to
 avoid potential breaking changes.

Parameters:
      * A (Tensor) -- lhs tensor of shape (, m, n)* where ***
        is zero or more batch dimensions.
  * **B** (*Tensor*) -- rhs tensor of shape *(*, m, k)* where ***
    is zero or more batch dimensions.

  * **rcond** (*float**, **optional*) -- used to determine the
    effective rank of "A". If "rcond"*= None*, "rcond" is set to
    the machine precision of the dtype of "A" times *max(m, n)*.
    Default: *None*.

Keyword Arguments:
      driver (str, optional) -- name of the LAPACK/MAGMA
