Describe the bug
Hello! I am trying to add ML-Agents to my Unity Project and I ran into an issue. When ever I tried to use mlagents-learn and then clicked Play in Unity Editor I've got error like this:

C:\Users\Lix\Secret\venv\lib\site-packages\torch\__init__.py:696: UserWarning: torch.set_default_tensor_type() is deprecated as of PyTorch 2.1, please use torch.set_default_dtype() and torch.set_default_device() as alternatives.
