 ### Pre-trained parameters
-Our QPIC have to be pre-trained with the COCO object detection dataset. For the HICO-DET training, this pre-training can be omitted by using the parameters of DETR. The parameters can be downloaded from here for [ResNet50](https://dl.fbaipublicfiles.com/detr/detr-r50-e632da11.pth), and for [ResNet101](https://dl.fbaipublicfiles.com/detr/detr-r101-2c7b67e5.pth). For the V-COCO training, this pre-training has to be carried out because some images of the V-COCO evaluation set are contained in the training set of DETR. We excluded the images and pre-trained QPIC for the V-COCO evaluation.

 After downloading or pre-training, move the pre-trained parameters to the `params` directory and convert the parameters with the following command (e.g. downloaded ResNet50 parameters).
