2. 预置条件
为了顺利按照本手册安装tensroflow object detection api,请参考Windows部署Docker GPU深度学习开发环境安装必备的工具。
若自行创建安装条件,请确保已经满足以下条件
• 支持python3.8以上版本• 支持cuda、cudnn(可选)• 支持git
本手册使用docker运行环境。
3. 安装步骤3.1 Docker环境3.1.1 启动docker
启动docker桌面客户端,如图所示:
1
3.1.2 启动容器
在windows平台可以启动命令行工具或者windows terminal工具(App Store下载),这里使用terminal工具。
输入以下命令,查看当前存在的images列表
PS C:\Users\xxxxx> docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEdocker/getting-started latest bd9a9f733898 5 weeks ago 28.8MBtensorflow/tensorflow 2.8.0-gpu-jupyter cc9a9ae2a5af 6 weeks ago 5.99GB
可以看到之前安装的tensorflow-2.8.0-gpu-jupyter镜像,现在基于这个镜像启动容器
docker run --gpus all -itd -v e:/dockerdir/docker_work/:/home/zhou/ -p 8888:8888 -p 6006:6006 --ipc=host cc9a9ae2a5af jupyter notebook --no-browser --ip=0.0.0.0 --allow-root --NotebookApp.token= --notebook-dir='/home/zhou/'
命令释义:docker run:表示基于镜像启动容器 --gpus all:不加此选项,nvidia-smi命令会不可用 -i: 交互式操作。-t: 终端。-d:后台运行,需要使用【docker exec -it 容器id /bin/bash】进入容器 -v e:/dockerdir/docker_work/:/home/zhou/:将windows平台的e:/dockerdir/docker_work/目录映射到docker的ubuntu系统的/home/zhou/目录下,实现windows平台和docker系统的文件共享 -p 8888:8888 -p 6006:6006:表示将windows系统的8888、6006端口映射到docker的8888、6006端口,这两个端口分别为jupyter notebook和tensorboard的访问端口 --ipc=host:用于多个容器之间的通讯 cc9a9ae2a5af:tensorflow-2.8.0-gpu-jupyter镜像的IMAGE ID jupyter notebook --no-browser --ip=0.0.0.0 --allow-root --NotebookApp.token= --notebook-dir='/home/zhou/': docker开机启动命令,这里启动jupyter
3.1.3 使用vscode访问docker container
启动vscode后,选择docker工具栏,在启动的容器上,右键选择附着到VsCode
2
3.1.4 更换docker容器ubuntu系统的安装源为国内源
在vscode软件界面上,选择【文件】-【打开文件夹】,选择根目录【/】,找到【/etc/apt/sources.list】,将ubuntu的安装源全部切换为aliyun源,具体操作为:将【archive.ubuntu.com】修改为【mirrors.aliyun.com】即可,修改后如下:

从nvcc -V的日志,可以看出cuda版本为11.2
• 输入以下命令,查询cuDNN版本
python -c "import tensorflow as tf;print(tf.reduce_sum(tf.random.normal([1000, 1000])))"
输出结果如下:
root@cc58e655b170:/usr# python -c "import tensorflow as tf;print(tf.reduce_sum(tf.random.normal([1000, 1000])))"2022-03-22 15:26:13.281719: I tensorflow/core/common_runtime/gpu/gpu_device.cc:1525] Created device /job:localhost/replica:0/task:0/device:GPU:0 with 3951 MB memory: -> device: 0, name: NVIDIA GeForce GTX 1660 Ti, pci bus id: 0000:01:00.0, compute capability: 7.5tf.Tensor(-2613.715, shape=(), dtype=float32)
从输出日志,可以看到GPU:NVIDIA GeForce GTX 1660 Ti已经加载到docker,cuDNN版本为7.5
3.2 Windows开发环境
同Docker环境,验证cuda和cuDNN安装情况。
3.3 下载tensorflow object detection api项目源码• 在home/zhou目录下创建tensorflow的目录
cd /home/zhou; mkdir tensorflow; cd tensorflow• 下载源码
git clone
下载完毕后,默认文件名名称为models-master, 将文件名重命名为models,保持文件名和平台一致
mv models-matser models
如果网速不好,直接下载zip压缩包吧
3
下载完毕后的文档结构如图所示:
tensorflow/└─ models/ ├─ community/ ├─ official/ ├─ orbit/ ├─ research/ └── ...3.4 安装配置protobuf
Tensorflow对象检测API使用Protobufs来配置模型和训练参数。在使用框架之前,必须下载并编译Protobuf库。
• 回到用户目录
cd /home/zhou• 下载protobuf 这里下载的已经预编译好的protobuf
wget -c• 解压 先执行mkdir protoc-3.19.4创建目录,然后执行unzip protoc-3.19.4-linux-x86_64.zip -d protoc-3.19.4/解压到制定目录protoc-3.19.4
root@cc58e655b170:/home/zhou# mkdir protoc-3.19.4root@cc58e655b170:/home/zhou# unzip protoc-3.19.4-linux-x86_64.zip -d protoc-3.19.4/Archive: protoc-3.19.4-linux-x86_64.zip creating: protoc-3.19.4/include/ creating: protoc-3.19.4/include/google/ creating: protoc-3.19.4/include/google/protobuf/ inflating: protoc-3.19.4/include/google/protobuf/wrappers.proto inflating: protoc-3.19.4/include/google/protobuf/source_context.proto inflating: protoc-3.19.4/include/google/protobuf/struct.proto inflating: protoc-3.19.4/include/google/protobuf/any.proto inflating: protoc-3.19.4/include/google/protobuf/api.proto inflating: protoc-3.19.4/include/google/protobuf/descriptor.proto creating: protoc-3.19.4/include/google/protobuf/compiler/ inflating: protoc-3.19.4/include/google/protobuf/compiler/plugin.proto inflating: protoc-3.19.4/include/google/protobuf/timestamp.proto inflating: protoc-3.19.4/include/google/protobuf/field_mask.proto inflating: protoc-3.19.4/include/google/protobuf/empty.proto inflating: protoc-3.19.4/include/google/protobuf/duration.proto inflating: protoc-3.19.4/include/google/protobuf/type.proto creating: protoc-3.19.4/bin/ inflating: protoc-3.19.4/bin/protoc inflating: protoc-3.19.4/readme.txt• 配置protoc 在~/.bashrc文件的末尾添加如下代码
export PATH=$PATH:/home/zhou/protoc-3.19.4/bin
执行如下命令,使其生效
source ~/.bashrc
执行echo $PATH查看是否生效
root@cc58e655b170:/home/zhou/protoc-3.19.4/bin# echo $PATH/home/zhou/protoc-3.19.4/bin:/home/zhou/protoc-3.19.4/bin:/home/zhou/protoc-3.19.4/bin:/root/.vscode-server/bin/c722ca6c7eed3d7987c0d5c3df5c45f6b15e77d1/bin/remote-cli:/usr/local/nvidia/bin:/usr/local/cuda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/zhou/protoc-3.19.4/bin
可以看到protoc的安装目录/home/zhou/protoc-3.19.4/bin已经添加到PATH了。
3.5 将proto后缀文件转换为python可识别格式• 切换目录
cd /home/zhou/tensorflow/models/research/• 查看转换前的目录文件列表
ls object_detection/protos/•4转换proto文件格式为python可识别序列化文件
protoc object_detection/protos/*.proto --python_out=.• 转换后,如下所示
ls object_detection/protos/
5
3.6 安装coco api
从TensorFlow 2.x开始, pycocotools包被列为对象检测API的依赖项。理想情况下,这个包应该在安装对象检测API时安装,如下面安装对象检测API一节所述,但是由于各种原因,安装可能会失败,因此更简单的方法是提前安装这个包,在这种情况下,稍后的安装将被跳过。
pip install cythonpip install git+
默认指标是基于Pascal VOC评估中使用的那些指标。要使用COCO对象检测指标,在配置文件的eval_config消息中添加metrics_set: "coco_detection_metrics"。要使用COCO实例分割度量,在配置文件的eval_config消息中添加metrics_set: "coco_mask_metrics"。
3.7 安装object detection api• 当前的工作路径应为
root@cc58e655b170:/home/zhou/tensorflow/models/research# pwd/home/zhou/tensorflow/models/research• 安装object detection api
cp object_detection/packages/tf2/setup.py .python -m pip install --use-feature=2020-resolver .
安装过程会持续一段时间,安装完毕后,可以执行如下代码,测试安装是否完成。
python object_detection/builders/model_builder_tf2_test.py
输出如下:
