1. What is PyTorch?
- A Python library
- A data analysis tool
- Open-source machine learning framework developed by Facebook
- A web framework
Show answer
Answer: Open-source machine learning framework developed by Facebook. PyTorch is an open-source machine learning framework developed by Facebook AI Research. It provides tensor computation and deep learning capabilities.
2. What is a tensor in PyTorch?
- A matrix
- A vector
- A scalar
- Multi-dimensional array similar to NumPy ndarray
Show answer
Answer: Multi-dimensional array similar to NumPy ndarray. A tensor is a multi-dimensional array, similar to NumPy ndarray but can run on GPUs. It is the fundamental data structure in PyTorch.
3. How do you create a tensor from a Python list?
- torch.from_list([1, 2, 3])
- torch.array([1, 2, 3])
- torch.tensor([1, 2, 3])
- tensor.create([1, 2, 3])
Show answer
Answer: torch.tensor([1, 2, 3]). Use torch.tensor([1, 2, 3]) to create a tensor from a Python list. torch.Tensor() is also available but torch.tensor() is preferred.
