another para

python3 is better

THis is good. A paragraph.

![Image](../a.png)
:label:`a.png`

Assume A

$$
X^{(N)} = \sum_{i=1}^N X_i.
$$
:label:`adsf`

and

$$\|\boldsymbol{x}\|_2 = \sqrt{\sum_{i=1}^n x_i^2}.$$

Here is a list
- sadf
  wer
  - asdf sadf
    sd sdf
- asdf

1. wer asdf
  asdf asdf

1. Run the code in this section. Change the conditional statement `x == y` in this section to `x < y` or `x > y`, and then see what kind of tensor you can get.
1. Replace the two tensors that operate by element in the broadcasting mechanism with other shapes, e.g., 3-dimensional tensors. Is the result the same as expected?
