でOpencv2.7いれて

http://arkouji.cocolog-nifty.com/blog/2016/08/tensorflowraspb.html

でclassfy_image.pyがない（そもそもmodelsディレクトリがない）ので、TensorFlowのソースみて

nano classify_image.py

"""Simple image classification with Inception.

Run image classification with Inception trained on ImageNet 2012 Challenge data
set.

This program creates a graph from a saved GraphDef protocol buffer,
and runs inference on an input JPEG image. It outputs human readable
strings of the top 5 predictions along with their probabilities.

Change the --image_file argument to any jpg image to compute a
classification of that image.

Please see the tutorial and website for a detailed description of how
to use this script to perform image recognition.

python classify_image.py

やって

giant panda, panda, panda bear, coon bear, Ailuropoda melanoleuca (score = 0.89107)
indri, indris, Indri indri, Indri brevicaudatus (score = 0.00779)
lesser panda, red panda, panda, bear cat, cat bear, Ailurus fulgens (score = 0.00296)
custard apple (score = 0.00147)
earthstar (score = 0.00117)

パンダ89%　インドリ（サル）0.7%、レッサーパンダ0.2%、custard apple（リンゴの仲間？）0.14％、アーススターって謎の花0.11%　じゃないって出る

わかりやすい解説

WEBアプリ化する

いろいろ入れるの

http://qiita.com/PonDad/items/9fbdf4d694f825dd1b6e

make runtest

で

.build_release/tools/caffe: error while loading shared libraries: libglog.so.0: cannot open shared object file: No such file or directory

が出る

対策？

sudo nano /etc/ld.so.conf

して、

末尾に

/usr/local/lib
/usr/lib

を追加

sudo ldconfig

する。

おわり

runtestで

[  FAILED  ] SGDSolverTest/0.TestSnapshotShare, where TypeParam = caffe::CPUDevice<float>

出るので

cd /etc

sudo nano profile

export CUDA_VISIBLE_DEVICES=0
export MKL_CBWR=AUTO
