Question about test AVA dataset

I want to run the pretrained model on test datset of ava. However it shows that cannot find such file.
`No such file or directory: 'ava/frames/xxxxxxxxxx/xxxxxxxx.jpg'`
but i have downloaded ava as dataset.md said.
So is that because it doesn't include test dataset? If so, how can i run the model on validation dataset？
Still thank you for your great codebase.
