A: No! PyTorch Hub is centered around open research and that extends to the usage of open datasets to train these models on. If a pull request for a proprietary model is submitted, we will kindly ask that you resubmit a model trained on something open and available.
Q: Where are my downloaded models saved?
A: We follow the XDG Base Directory Specification and adhere to common standards around cached files and directories.
The locations are used in the order of:

Calling hub.set_dir(<PATH_TO_HUB_DIR>)
$TORCH_HOME/hub, if environment variable TORCH_HOME is set.
$XDG_CACHE_HOME/torch/hub, if environment variable XDG_CACHE_HOME is set.
~/.cache/torch/hub
