Each element contains ``C`` feature maps of dimensions ``H x W``. boxes (Tensor[K, 5] or List[Tensor[L, 4]]): the box coordinates in (x1, y1, x2, y2) format where the regions will be taken from. The coordinate must satisfy ``0 <= x1 < x2`` and ``0 <= y1 < y2``. If a single Tensor is passed, then the first column should contain the index of the corresponding element in the batch, i.e. a number in ``[0, N - 1]``. If a list of Tensors is passed, then each Tensor will correspond to the boxes for an element i in the batch. output_size (int or Tuple[int, int]): the size of the output after the cropping is performed, as (height, width) spatial_scale (float): a scaling factor that maps the box coordinates to the input coordinates. For example, if your boxes are defined on the scale of a 224x224 image and your input is a 112x112 feature map (resulting from a 0.5x scaling of the original image), you'll want to set this to 0.5. Default: 1.0 Returns: Tensor[K, C, output_size[0], output_size[1]]: The pooled RoIs. rr )torchjit is_scripting is_tracingr roi_poolrr r isinstancerr ops torchvision)rrrrroisoutput_s j/var/www/tools.fuzzalab.pt/emblema-extractor/venv/lib/python3.11/site-packages/torchvision/ops/roi_pool.pyrrs< 9 ! ! # #&EI,@,@,B,B&H%%%%   D $$K dEL ) )1*400 %..udM;WX>[fgh[ijjIFA McteZdZdZdeedeffd Zdede ee efdefdZ de fd Z xZS) RoIPoolz See :func:`roi_pool`. rrctt|||_||_dSN)super__init__r rr)selfrr __class__s r r'zRoIPool.__init__=s= D!!!&*r!rrrc:t|||j|jSr%)rrr)r(rrs r forwardzRoIPool.forwardCstT%5t7IJJJr!cD|jjd|jd|jd}|S)Nz (output_size=z, spatial_scale=))r)__name__rr)r(ss r __repr__zRoIPool.__repr__Fs1~& l lT5E l lW[Wi l l lr!)r. __module__ __qualname____doc__rintfloatr'rrlistr+strr0 __classcell__)r)s@r r#r#8s+$5c$:+5++++++ KVK5f1E+FK6KKKK#r!r#)r)typingrrtorch.fxrrtorch.jit.annotationsrtorch.nn.modules.utilsrtorchvision.extensionrutilsr _utilsr r fxwrapr6r4r5rModuler#r!r rDsG 333333((((((111111''''''FFFFFFFF  && & f% &&#3'& &  &&&&Rbir!
