整体来看,TensorFlow还是有点繁琐的 Pytorch Pytorch 也有一个类似的基类,只不过名字更加直接点,就叫torch.utils.data.Dataset,顾名思义,这个是用来创建自定义的数据集类。其文档链接如下 Writing Custom Datasets, DataLoaders and Transforms Datasets & DataLoaders torch.utils.data - PyTorch 1.10.0 documentation 关...

anaconda安装 1.百度搜索anacounda直接安装 2.注意:下载文件后直接下一步下一步就好了,(要选择的全部打勾:尤其是环境变量添加到路径中) CUDA安装 1.百度搜索:CUDA download进入官网查找,或者选择https://developer.nvidia.com/cuda-toolkit-archive,来选择对于的版本。 2.安装下载后的exe文件,一直点击下一步下一...

支持多模态/单模态检测器,包括 MVXNet,VoteNet,PointPillars 等。 支持户内/户外的数据集 支持室内/室外的3D检测数据集,包括 ScanNet, SUNRGB-D, Waymo, nuScenes, Lyft, KITTI. 对于nuScenes 数据集, 我们也支持nuImages 数据集. 与2D 检测器的自然整合 ...
This change is transparent to Python users, but the whole C++ backend for video reading (which needs torchvision to be compiled from source for it to be enabled for now) has been refactored into more modular abstractions. The core abstractions are in https://github.com/pytorch/vision/tree/ma...
