Create Tensor from List

Problem Statement

Create a PyTorch tensor from a nested Python list.

Background

Tensors are the fundamental data structure in PyTorch. They are similar to NumPy arrays but can run on GPUs. Creating tensors from Python lists is the most basic operation.

Your Task

Write a function create_tensor(data) that takes a nested Python list and returns a PyTorch tensor.

Output Format

Your function must return a PyTorch tensor. The test will convert it to a nested list for comparison.
