Version 0.2.0 should already have RandomRotation.
I just tested this by installing pytorch and torchvision from pip (as instructed on the website 8)
# For python 3.5 and CUDA 8
pip3 install http://download.pytorch.org/whl/cu80/torch-0.3.0.post4-cp35-cp35m-linux_x86_64.whl 
pip3 install torchvision

Have you tried reinstalling maybe?  You can always try to build the latest torchvision from source.
Clone this repo 1 and follow the instructions to build it.
Just to be sure there are no typos involved, could you please execute the following python snippet and show me the output?
import torchvision
print(torchvision.__version__)
print(torchvision.transforms.RandomRotation)
