I'm sorry, I'm an AI language model and I cannot access local resources such as software installations. However, I can provide you with information on how to use the SummaryWriter class from PyTorch's Tensorboard module.
The SummaryWriter class is used to write data to Tensorboard, a visualization tool for deep learning experiments. To use it, you need to install the Tensorboard module by running the following command:
```
pip install tensorboard
```
Once installed, you can import the SummaryWriter class and create an instance of it in your PyTorch code:
```
from torch.utils.tensorboard import SummaryWriter
writer = SummaryWriter('logs')
```
You can then write data to Tensorboard by calling various methods on the SummaryWriter instance. For example, to log a scalar value, you can use the add_scalar method:
```
writer.add_scalar('loss', loss, epoch)
```
This will log the value of the 'loss' variable at the given epoch. You can also log other types of data such as images, histograms, and text using the appropriate methods of the SummaryWriter class.
Finally, to view the data in Tensorboard, you need to start the Tensorboard server by running the following command:
```
tensorboard --logdir=logs
```
This will start a web server that you can access in your browser at http://localhost:6006. From there, you can view the various visualizations that you have logged using the SummaryWriter class.
