# Unit 10 Exercises

## Exercise 1: Using Fabric

It’s been a while since we used pure PyTorch code in Unit 4. If you are interested in using Fabric, a good exercise is to convert the existing PyTorch code into Fabric — it only requires changing a handful of lines.

For this, you can use this template based on the MNIST classifier from Unit 4.

Remember, the conversion to Fabric involves

- Setting up the model and optimizer via
`fabric.setup(model, optimizer)`

- Converting the data loaders via
`fabric.setup_dataloaders`

Hint: If you prefer to run this code on a CPU instead of GPU, you don’t need to specify the accelerator. Or just set it to `accelerator="cpu"`

.

## Exercise 2: Confidence Intervals

If you want to practice using the confidence interval method introduced in this lecture, tru to compute a confidence interval for the MNIST classifier from Unit 4 using this template.

Hint: In this case, since it’s a relatively large test set, the confidence interval is less than a percentage point wide.

And for a more advanced challenge, you can also try to implement the other 3 confidence interval methods for this MNIST classifier.
