Tensorflow Object Detection

聽同學說Tensorflow 

最近才開始學習不過沒關西還是完成他，下一個框架，可能挑PyTorch 之類的可以去找看看。

Clone TensorFlow Models



PIP Install

pip install pillow
pip install lxml
pip install jupyter
pip install matplotlib





Install protoc
"C:/Program Files/protoc/bin/protoc" object_detection/protos/*.proto --python_out=.



Cd D:\Programming\python\protoc-3.4.0-win32\bin



切錯囉


跟影片有出入新版的下載完research 才是影片的models

錯誤情況 0x1

Traceback (most recent call last):
File "C:\Users\x2132\Desktop\pyhton\tesorflow\test1\test2.py", line 33, in <module>

這邊可以看到我跟影片的不一樣，額切到D:\Programming\python\model\research並且下指令
python setup.py build
python setup.py install

然後再切到這邊可以看到我們的python也自動裝上了

接下來我們跑一下程式碼可以看到我們安裝的python 套件資料夾有了一個object_detection-0.1-py3.6.egg 然後呢我們點進去。
這邊裡面原本沒有data 這個資料夾，所以呢,我們呢從我們下載下來的tensorflow/research/data我們把它複製過去非常重要。


PATH_TO_LABELS = os.path.join('C:/Users/x2132/AppData/Local/Programs/Python/Python36/Lib/site-packages/object_detection-0.1-py3.6.egg/object_detection/data', 'mscoco_label_map.pbtxt')


 pip install -e slim


然後呢這就是以上兩種可能發生的錯誤。stackoverflow.com 挖了 1天呢。

啟動

python D:\Programming\python\model\research\object_detection\builders\model_builder_test.py


可以發現運行得非常順利我們來上代碼。
