Box2boxtransform
WebThe transformation is parameterized by 5 deltas: (dx, dy, dw, dh, da). The transformation scales the box's width and height by exp (dw), exp (dh), shifts a box's center by the offset … WebIf the above script is called disable_jit_example.py, we can invoke it like so: $ PYTORCH_JIT=0 python disable_jit_example.py. and we will be able to step into the @torch.jit.script function as a normal Python function. To disable the TorchScript compiler for a specific function, see @torch.jit.ignore.
