Very simple multi-layer perceptron (also called FFN)

Track a series of values and provide access to smoothed values over a window or the global series average.

Computes and stores the average and current value

ResNet backbone with frozen BatchNorm.

A basic Swin Transformer layer for one stage. Args: dim (int): Number of feature channels depth (int): Depths of this stage.

This is the Cross-Attention Detector module that performs object detection

Multilayer perceptron.

Image to Patch Embedding Args: patch_size (int): Patch token size. Default: 4. in_chans (int): Number of input image channels. Def

Absolute pos embedding, learned.

This is a more standard version of the position embedding, very similar to the one used by the Attention is all you need paper, generalized t

This module converts the model's output into the format expected by the coco api

Swin Transformer backbone. A PyTorch impl of : `Swin Transformer: Hierarchical Vision Transformer using Shifted Windows` - https://

Swin Transformer Block. Args: dim (int): Number of input channels. num_heads (int): Number of attention heads. window_size

Window based multi-head self attention (W-MSA) module with relative position bias. It supports both of shifted and non-shifted window. Args:

argparse action to split an argument into KEY=VALUE form on the first = and append to a dictionary. List options should be passed as comm

This class takes as input a set of embeddings of dimension C1 and outputs a set of embedding of dimension C2, after a linear transformation,

BatchNorm2d where the batch statistics and the affine parameters are fixed. Copy-paste from torchvision.misc.ops with added eps before rqsrt

Multi-Scale Deformable Attention Module used in Deformable-DETR `Deformable DETR: Deformable Transformers for End-to-End Object Detection. <h

Inherit from this class and define ``__nice__`` to "nicely" print your objects. Defines ``__str__`` and ``__repr__`` in terms of ``__nice__``

Patch Merging Layer Args: dim (int): Number of input channels. norm_layer (nn.Module, optional): Normalization layer. Default: nn

This is a more standard version of the position embedding, very similar to the one used by the Attention is all you need paper, generalized t

Randomly selects between transforms1 and transforms2, with probability p for transforms1 and (1 - p) for transforms2
