该分支内有两个部分,分别处理trainval和test数据,且都是通过nuscenes_data_prep()实现的,所以这里只看如何处理trainval的,主要是nuscenes_data_prep()这个函数。 3.nuscenes_data_prep() def nuscenes_data_prep(root_path,# ./data/nuscenes info_prefix, # nuscenes version, # v1.0-trainval dataset_name, ...
有一些常见的钩子是通过 default_hooks 注册的,它们是 IterTimerHook:记录 “data_time” 用于加载数据和 “time” 用于模型训练步骤的钩子。 LoggerHook:从Runner的不同组件收集日志并将它们写入终端、JSON文件、tensorboard和 wandb 等的钩子。 ParamSchedulerHook:更新优化器中一些超参数的钩子,例如学习率和动量。 C...

waymo dataset v1.3.1或者v1.3.2在github上有配套的waymo-open-dataset工程,里面有tutorial和data frame的protobuf定义,基于tensorflow实现了一些提取数据集的功能。 使用mmdetection(3d)框架跑waymo dataset的时候,需要用到上述工程提取waymo dataset数据,并转换成kitti格式,这样,mmdet3d里的pointpillar就能直接跑dataset了。

If you already have done the above, then the distributed data parallel module wasn’t able to locate the output tensors in the return value of your module’s forward function. Please include the loss function and the structure of the return value of forward...
或者你可以通过将 --cfg-options 设置为 --cfg-options data.test.samples_per_gpu=2 来开启它。 弃用ImageToTensor 在测试模式下,弃用 ImageToTensor 流程,取而代之的是 DefaultFormatBundle。建议在你的测试数据流程的配置文件中手动替换它,如: # (已弃用)使用 ImageToTensor pipelines = [ dict(type='LoadIma...
Once the data is all prepped and ready to go, it's time to get the Cascade model geared up for some serious training action! We're talking about picking out the perfect backbone network, anchor scales, and ratios – all the stuff that's going to make our model really shine. In MMDete...
