Saving model state_dict in PyTorch - Interactive Code Practice

Practice - 5 Tasks

Complete the code to save the model's state dictionary to a file.

PyTorch

torch.save(model.[1](), 'model.pth')

💡 Hint

Common Mistakes

Using 'parameters' instead of 'state_dict' causes an error because 'parameters' is a generator, not a dictionary.

Trying to call a non-existent method like 'save_state'.

The state_dict() method returns the model's parameters as a dictionary, which is what we save.

Complete the code to load the saved state dictionary into the model.

PyTorch

model.load_state_dict(torch.[1]('model.pth'))

💡 Hint

Common Mistakes

Using 'load_state_dict' as a torch function causes an error because it is a model method, not a torch function.

Using 'load_model' or 'load_file' which do not exist.

The torch.load() function loads the saved dictionary from the file.

Fix the error in saving the model's state dictionary by completing the code.

PyTorch

torch.save([1], 'model.pth')

💡 Hint

Common Mistakes

Trying to save the whole model object causes errors or large files.

Using 'model.parameters()' returns a generator, not a dictionary.

Only model.state_dict() returns the dictionary of parameters suitable for saving.

4fill in blank

hard

Fill both blanks to save the model's state dictionary and then load it back.

PyTorch

torch.[1](model.[2](), 'model.pth')
model.load_state_dict(torch.load('model.pth'))

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

💡 Hint

Common Mistakes

Using 'parameters' instead of 'state_dict' causes errors.

Using 'load' instead of 'save' for saving.

Use torch.save to save and model.state_dict() to get the parameters.

5fill in blank

hard

Fill all three blanks to save the model's state dictionary, load it, and update the model.

PyTorch

torch.[1](model.[2](), 'model.pth')
loaded_dict = torch.[3]('model.pth')
model.load_state_dict(loaded_dict)

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

💡 Hint

Common Mistakes

Mixing up save and load functions.

Using 'parameters' instead of 'state_dict' for saving.

First save with torch.save, get parameters with state_dict(), then load with torch.load.
