How to Retrain Inception's Final Layer for New Categories

步驟：

一　Installing TensorFlow on Ubuntu   

https://www.tensorflow.org/install/install_linux

二　Install Bazel on Ubuntu

https://bazel.build/versions/master/docs/install-ubuntu.html

三　下載代碼　

git clone https://github.com/tensorflow/tensorflow.git

~/tensorflow$  ./configure

四　編譯

bazel build tensorflow/examples/p_w_picpath_retraining:retrain

五　注意事項：

1  bazel-bin/tensorflow/examples/label_p_w_picpath/label_p_w_picpath --graph=/tmp/output_graph.pb --labels=/tmp/output_labels.txt --output_layer=final_result --p_w_picpath=/home/camille/Desktop/timg.jpg

命令報錯：

017-06-20 12:52:52.774446: E tensorflow/examples/label_p_w_picpath/main.cc:350] Running model failed: Not found: FeedInputs: unable to find feed output input

解決方案：在后面加一句　--input_layer=Mul //this parameter update the input and output layer names to "Mul" and "final_result" respectively

２下載tensorflow 代碼時，

git clone https://github.com/tensorflow/tensorflow.git

直接執行　bazel build tensorflow/examples/p_w_picpath_retraining:retrain

報錯　build aborted

解決方案：　執行　./configure 

再執行　bazel build tensorflow/examples/p_w_picpath_retraining:retrain　就沒問題了。

３　　Bazel　安裝之前一定要安裝jdk

sudo apt-get install oracle-java8-installer

I recommend you to use Webup8 Oracle Java8 Installer

sudo add-apt-repository ppa:webupd8team/java

sudo apt update; sudo apt-get install oracle-java8-installer

or 

sudo apt update; sudo apt-get install oracle-java8-set-default

4 執行　

bazel-bin/tensorflow/examples/p_w_picpath_retraining/retrain --p_w_picpath_dir ~/flower_photos

時報錯：1)

   File "/home/karthik/tensorflow/bazel-bin/tensorflow/examples/p_w_picpath_retraining/retrain.runfiles/org_tensorflow/tensorflow/python/util/tf_should_use.py", line 28, in <module>
        from backports import weakref  # pylint: disable=g-bad-import-order
    ImportError: No module named backports

解決方案：安裝所需module

sudo pip install backports.weakref
sudo pip3 install backports.weakref

報錯2) 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named numpy
Is numpy installed?

解決方案： sudo apt-get install python-numpy

5 ImportError: No module named mock

實際上安裝了，所以只能先刪除再安裝了

解決方案：　

$ sudo rm -rf /usr/local/lib/python2.7/dist-packages/mock
$ sodo rm -rf /usr/local/lib/python2.7/dist-packages/mock-2.0.0.dist-info

then type the following command to install mock

$ sudo pip install --upgrade mock
