Saving entire model in PyTorch - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to save the entire PyTorch model to a file.

PyTorch

import torch

# Assume model is a PyTorch model
torch.save(model, [1])

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

Amodel.state_dict()

B"model.pth"

C"weights.pth"

Dtorch.nn.Module()

💡 Hint

Common Mistakes

Using model.state_dict() instead of the whole model.

Not providing a filename as a string.

Passing a model class instead of an instance.

To save the entire model in PyTorch, use torch.save(model, 'filename') where the filename is a string.

2fill in blank

medium

Complete the code to load the entire PyTorch model from a file.

PyTorch

import torch

model = torch.load([1])

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

A"model.pth"

Bmodel.state_dict()

Ctorch.nn.Module()

D"weights.pth"

💡 Hint

Common Mistakes

Passing model.state_dict() instead of a filename.

Using the wrong filename string.

Trying to load weights only instead of the whole model.

To load a saved entire model, use torch.load('filename') with the filename as a string.

3fill in blank

hard

Fix the error in the code to save the entire model correctly.

PyTorch

import torch

# Incorrect saving code
torch.save([1], "model.pth")

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

Atorch.nn.Module()

Bmodel.state_dict()

💡 Hint

Common Mistakes

Saving model.state_dict() when intending to save the whole model.

Passing a string instead of the model object.

Passing a new model instance instead of the trained model.

To save the entire model, pass the model instance itself, not its state dictionary.

4fill in blank

hard

Fill both blanks to save and then load the entire PyTorch model.

PyTorch

import torch

# Save model
torch.save([1], [2])

# Load model
loaded_model = torch.load("model.pth")

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

Amodel

Bmodel.state_dict()

C"model.pth"

D"weights.pth"

💡 Hint

Common Mistakes

Saving model.state_dict() instead of the whole model.

Using wrong filename strings.

Mixing up save and load functions.

Use torch.save(model, 'model.pth') to save and torch.load('model.pth') to load the entire model.

5fill in blank

hard

Fill all three blanks to save the entire model, load it, and print its type.

PyTorch

import torch

# Save the model
torch.save([1], [2])

# Load the model
loaded_model = torch.load([3])

print(type(loaded_model))

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

B"model.pth"

Dmodel.state_dict()

💡 Hint

Common Mistakes

Using different filenames for saving and loading.

Saving model.state_dict() instead of the whole model.

Passing wrong arguments to torch.load.

Save the model with torch.save(model, 'model.pth'), load it with torch.load('model.pth'), then print its type.
