*TensorflowCaffeのTutorialを試してみる (2016-03-28〜 ) [#m8f810c5]

[[Download and Setup:https://www.tensorflow.org/versions/r0.7/get_started/os_setup.html#test-the-tensorflow-installation]]

**インストール [#b7282b02]
Pip installで済ませる。CUDAやdecunnはインストール済み
Pip installで済ませる。CUDAやcuDNNはインストール済み

cuDNNのインストールは、まず登録してlinux用のtgzファイルをダウンロード。/usr/local/cuda/の下へ追加する形でdynamic libraryファイルやinclude headerファイルを置いただけ。

Run a TensorFlow demo modelを試してみる
 $ python -c 'import os; import inspect; import tensorflow; print(os.path.dirname(inspect.getfile(tensorflow)))'

MNISTデータを試してみる。(convolutionらしい)
 python /usr/local/anaconda/lib/python2.7/site-pack
ages/tensorflow/models/image/mnist/convolutional.py

結果は、
