Parameters:
         * n (Int, optional) -- The length of sequence of
           points to draw. Default: 1
     * **out** (*Tensor**, **optional*) -- The output tensor

     * **dtype** ("torch.dtype", optional) -- the desired data
       type of the returned tensor. Default: "torch.float32"

  Return type:
     *Tensor*

draw_base2(m, out=None, dtype=torch.float32)
  Function to draw a sequence of "2**m" points from a Sobol
  sequence. Note that the samples are dependent on the previous
  samples. The size of the result is (2**m, dimension).

  Parameters:
     * **m** (*Int*) -- The (base2) exponent of the number of
       points to draw.

     * **out** (*Tensor**, **optional*) -- The output tensor

     * **dtype** ("torch.dtype", optional) -- the desired data
       type of the returned tensor. Default: "torch.float32"

  Return type:
     *Tensor*
