# 8.2 安装 Detectron2
python -m pip install 'git+https://github.com/facebookresearch/detectron2.git'# 9 下载预训练模型
# 9.1 进入bevformer目录
cd bevformer
# 9.2 创建并进入ckpts文件夹
mkdir ckpts && cd ckpts
# 9.3 下载预训练权重r101_dcn_fcos3d_pretrain.pth，github加速代理https://ghproxy.com/
wget https://github.com/zhiqi-li/storage/releases/download/v1.0/r101_dcn_fcos3d_pretrain.pth
1.2 运行报错汇总
# 报错1 ImportError: libGL.so.1: cannot open shared object file: No such file or directory
# 修改：安装libsm6 libxext6 libgl1-mesa-glx
apt-get install libsm6 libxext6 libgl1-mesa-glx# 报错2 ImportError: libgthread-2.0.so.0: cannot open shared object file: No such file or directory
# 修改：安装libglib2.0-dev
apt-get install libglib2.0-dev# 报错3 ModuleNotFoundError: No module named 'tools'
# 修改：添加python环境变量
export PYTHONPATH="./"# 报错4
# from data_converter import indoor_converter as indoor
# File "/home/lin/Documents/BEVFormer/tools/data_converter/indoor_converter.py", line 6, in <module>
# from tools.data_converter.s3dis_data_utils import S3DISData, S3DISSegData
# ModuleNotFoundError: No module named 'tools.data_converter'修改：./tools/data_converter/indoor_converter.py的6-8行位置左右
将from tools.data_converter.s3dis_data_utils import S3DISData, S3DISSegData改成由from data_converter.s3dis_data_utils import ...
也就是tools.data_converter换成data_converter# 错误5 TypeError: FormatCode() got an unexpected keyword argument 'verify'
# 修改：更新yapf版本为0.40.1
pip install yapf==0.40.1# 错误6 显存爆炸
# 修改：samples_per_gpu=1, 48G显存设2显存就炸了, bev没钞能力还是不要玩 我没用use_can_bus将配置文件中use_can_bus改为False,生成数据use_can_bus有关的代码注释掉
