下載完後解壓，放在哪裡是一個問題，推薦地址： /home/zhangjun/miniconda3/envs/tensorflow 下面。我一開始在 /home/zhangjun/ 目錄下建立了一個資料夾 Tensorflow ,放在這個資料夾下面了

2. Tensorflow Object Detection API 以來以下庫檔案
   Tensorflow Object Detection API depends on the following libraries:

   Protobuf 3.0.0
   Python-tk
   Pillow 1.0
   lxml
   tf Slim (which is included in the “tensorflow/models/research/” checkout)
   Jupyter notebook
   Matplotlib
   Tensorflow (>=1.9.0)
   Cython
   contextlib2
   cocoapi

The remaining libraries can be installed on Ubuntu 16.04 using via apt-get:

sudo apt-get install protobuf-compiler python-pil python-lxml python-tk
pip install --user Cython
pip install --user contextlib2
pip install --user jupyter
pip install --user matplotlib
 

3）手動安裝 protobuf， protobuf 3.6 可能有問題，我後來又用了 protobuf3.0.0
If you are on linux:

Download and install the 3.0 release of protoc, then unzip the file.

# From tensorflow/models/research/
wget -O protobuf.zip https://github.com/google/protobuf/releases/download/v3.0.0/protoc-3.0.0-linux-x86_64.zip
unzip protobuf.zip

Run the compilation process again, but use the downloaded version of protoc

# From tensorflow/models/research/
./bin/protoc object_detection/protos/*.proto --python_out=.

4. Add Libraries to PYTHONPATH

   From tensorflow/models/research/

export PYTHONPATH=$PYTHONPATH:`pwd`:`pwd`/slim

5） python object_detection/builders/model_builder_test.py
報錯
ubuntu16.04 ‘No module named ‘object_detection’’
https://blog.csdn.net/weixin_41683218/article/details/81214785

/home/zhangjun/miniconda3/envs/tensorflow/lib/python3.6/site-packages
建立檔案
tensorflow_model.pth
檔案內容如下：
/home/zhangjun/Tensorflow/models/research
/home/zhangjun/Tensorflow/models/research/slim

再執行 python object_detection/builders/model_builder_test.py
沒有問題了

Ran 7 tests in 0.024s

OK

6）接下來，跑一個demo，你可以在這個路徑下執行jupyter notebook
報錯： jupyter: command not found
路徑問題
~/.local/bin/jupyter-notebook

找不到 /object_detection/object_detection_tutorial.ipynb

在 /home/zhangjun/Tensorflow/models/research/object_detection
下面執行 ~/.local/bin/jupyter-notebook
就可以看到了 /object_detection/object_detection_tutorial.ipynb
