KeyError: 'radar'`

[chg0901]

I have an error when I try to use your code.

File "/home/user/Documents/GitHub/bevfusion/mmdet3d/datasets/pipelines/loading.py", line 728, in __call__ radars_dict = results['radar'] KeyError: 'radar'

And I found a simiar iusse in another project

Is it because I put the mmdetection3d github folder into the project and install it before I run python setup.py develop so the mmdetection3d could affect the result?

The following are the outputs after I run python setup.py develop

Removing mmdet3d 1.0.0rc0 from easy-install.pth file

did you know how to solve this problem? Thank you very much for your help and reply~

Here I want to share what I have done with nuscene mini dataset and this code (even it is with some Chinese, I help this could help people want to use this code)

conda create --name fusionbev python=3.8 -y

pip install lyft-dataset-sdk

conda install pytorch==1.10.1 torchvision==0.11.2 torchaudio==0.10.1 cudatoolkit=11.3 -c pytorch -c conda-forge

#下载openmpi 见最下面

git clone https://github.com/open-mmlab/mmsegmentation.git

## 创建pkl文件
# https://mmdetection3d.readthedocs.io/zh_CN/dev-1.x/advanced_guides/datasets/nuscenes.html

# cd到mmdetection3d文件夹，注意root path多位置和version的设置
# ./tools/create_data.py  line 120
#     elif args.dataset == "nuscenes" and args.version == "v1.0-mini":

python ./tools/create_data.py nuscenes --root-path ../data/nuscenes --out-dir ../data/nuscenes --extra-tag nuscenes --version v1.0-mini

## mmdet3d 1.0.0rc0 requires numba==0.53.0, but you have numba 0.58.0 which is incompatible.
pip install numba==0.53.0
pip install numpy==1.23.4

#下载openmpi
# 参考 https://blog.csdn.net/qq_26822029/article/details/107930758
到openmpi官网下载openmpi，这里我使用的是4.0.4版本，也可以使用wget下载：

wget https://download.open-mpi.org/release/open-mpi/v4.0/openmpi-4.0.4.tar.gz

下载完成之后解压：

tar -zxvf openmpi-4.0.4.tar.gz

进入openmpi-4.0.4文件夹之后检查配置文件

cd openmpi-4.0.4
./configure

在漫长的等待之后编译安装

sudo make all install

编译完成之后需要配置一下openmpi的环境变量

vim /etc/profile

# 在这个文件末尾添加如下两行
export PATH=/usr/local/path:$PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

编辑完成之后需要执行source /etc/profile使其生效

进入到examples文件夹中，执行make编译一下测试代码，如果编译没有报错执行下面的测试语句

make # 先make再执行下面一句 ！！！！！
mpirun -np 4 hello_c

如果正常输出结果则说明安装完成~
