# Pt Index Select
Extracts elements from the input tensor along a specified dimension using an index tensor.

`dim` specifies the dimension along which the selection occurs.
* For example, for 2D tensors:
** If `dim=0`, `index` selects rows.
** If `dim=1`, `index` selects columns (for 2D tensors).

`index` is a list of indices that will be converted into a tensor.

Example:
```
Input Tensor:
[[1, 2, 3],
 [40, 50, 60],
 [700, 800, 900]]

index = "[0, 2]"
dim = 0

Output Tensor:
[[1, 2, 3],
 [700, 800, 900]]
```
