convert tf.reshape to pytorch

To convert `tf.reshape` to PyTorch, you can use the `view` method in PyTorch. Here's an example:

# TensorFlow code:
import tensorflow as tf

x = tf.constant([[1, 2], [3, 4], [5, 6]])
y = tf.reshape(x, [2, 3])

# PyTorch equivalent:
import torch

x = torch.tensor([[1, 2], [3, 4], [5, 6]])
y = x.view(2, 3)

In this example, `x` is a 3x2 tensor, and `y` is the reshaped tensor with shape 2x3. The `view` method in PyTorch works similarly to `tf.reshape` in TensorFlow.
