Tensor creation (torch.tensor, zeros, ones, rand) in PyTorch - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a tensor from a list of numbers.

PyTorch

import torch

my_tensor = torch.[1]([1, 2, 3, 4])
print(my_tensor)

💡 Hint

Common Mistakes

Using torch.zeros or torch.ones instead of torch.tensor.

Trying to call torch.rand with a list argument.

The torch.tensor function creates a tensor from a Python list or array.

2fill in blank

medium

Complete the code to create a 3x3 tensor filled with zeros.

PyTorch

import torch

zero_tensor = torch.[1]((3, 3))
print(zero_tensor)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using torch.ones instead of torch.zeros.

Passing a list instead of a tuple for the shape.

torch.zeros creates a tensor filled with zeros of the given shape.

3fill in blank

hard

Fix the error in the code to create a 2x4 tensor filled with ones.

PyTorch

import torch

one_tensor = torch.[1]([2, 4])
print(one_tensor)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using torch.tensor instead of torch.ones.

Using torch.zeros which creates zeros instead of ones.

torch.ones creates a tensor filled with ones. The shape must be passed as a tuple, but a list also works here.

4fill in blank

hard

Fill both blanks to create a 4x2 tensor with random values between 0 and 1.

PyTorch

import torch

random_tensor = torch.[1]([2])
print(random_tensor)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using torch.ones instead of torch.rand.

Passing the shape as a list instead of a tuple.

torch.rand creates a tensor with random values between 0 and 1. The shape must be a tuple like (4, 2).

5fill in blank

hard

Fill all three blanks to create a tensor from a list, then create zeros and ones tensors with the same shape.

PyTorch

import torch

base_tensor = torch.[1]([5, 6, 7])
zeros_tensor = torch.[2](base_tensor.[3])
ones_tensor = torch.ones(base_tensor.shape)

print(base_tensor)
print(zeros_tensor)
print(ones_tensor)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using torch.ones instead of torch.zeros for the zeros tensor.

Using .size() instead of .shape (both work but .shape is more common).

Using torch.rand instead of torch.tensor for the base tensor.

First, torch.tensor creates a tensor from a list. Then torch.zeros creates a zeros tensor with the same shape accessed by shape.
