+    Computes pairwise distances between sets of vectors in tensors x1 and x2 using the p-norm. The function treats the last dimension
+    of x1 and x2 as feature dimensions, which must be identical for both inputs. The second-to-last dimensions can differ, reflecting
+    the number of vectors in each tensor. The dimensions preceding the last are considered as batch dimensions, and pairwise distances
+    are computed for each matching set in these dimensions.
+
+    The output tensor's shape is derived by matching the batch dimensions of x1 and x2, where the mismatched batch dimensions are
+    merged, and the resulting shape reflects the computed distances for each pair of vectors. It's crucial that the batch dimensions
+    (except for the size of sets of vectors to compare) of x1 and x2 either match or one of them is 1 (broadcasting).
+
+    Args:
+        x1 (Tensor): input tensor of shape B x P x M.
+        x2 (Tensor): input tensor of shape B x R x M.
+        p (float): p value for the p-norm distance to calculate between each vector pair
+        compute_mode (int): Controls the computation method based on the size of the input sets:
+            - None ('use_mm_for_euclid_dist_if_necessary'): Default mode. Uses matrix multiplication to calculate
+              Euclidean distance (p=2) if either the number of vectors in x1 or x2 exceeds 25 (P > 25 or R > 25).
+            - 1 ('use_mm_for_euclid_dist'): Always use matrix multiplication approach to calculate
+            euclidean distance (p = 2)
+            - 2 ('donot_use_mm_for_euclid_dist'): Never use matrix multiplication approach to calculate
+            euclidean distance (p = 2)
+
+    Example:
+    - If x1.shape = [2, 3, 10, 5] and x2.shape = [2, 3, 20, 5], both having the same batch dimensions [2, 3], the output shape will be [2, 3, 10, 20].
+      This represents computing distances in two batches of three groups, each comparing 10 vectors from x1 with 20 vectors from x2.
+    - For x1.shape = [10, 5] (10 vectors, each of 5 features) and x2.shape = [20, 5] (20 vectors, each of 5 features),
+      since there are no batch dimensions to match, the output shape is simply [10, 20], comparing all vectors from x1 against all vectors from x2.
+
+    Note: The `compute_mode` parameter is designed to optimize the performance of the Euclidean distance calculation,
+    especially useful when working with large datasets. This parameter allows you to control how the distances are computed,
+    with different modes available to leverage matrix multiplication for speed improvements.
