PyTorch get_device_capability() Output Explanation
when running torch.cuda.get_device_capability() on my GTX 1070 I get the following output: (6, 1).
Could someone explain what this means?

As stated in the comment, those are actully your GPU's compute capability version/indicator.
To put it simply, it describes the features supported by your GPU. You can also view your GPU compute capability using GPU-Z if you are on windows.
For more information concerning the exact feature set differences you can have a look Here.

As you can see here, based on, these allows the developers to know which feature-set is available to them and thus enable some features for some hardwares if they support it and otherwise fall back to other implementations of them.
This may be useful as well.
