Raspberry Pi を利用した機械学習について試す。

OpenCV、TensorFlow、Kerasをインストール

3 wget https://github.com/mt08xx/files/raw/master/opencv-rpi/libopencv3_3.4.0-20180115.1_armhf.deb
4 sudo apt install -y ./libopencv3_3.4.0-20180115.1_armhf.deb
5 sudo ldconfig
6 pip3 install numpy==1.13
7 sudo apt-get install libblas-dev liblapack-dev python3-dev libatlas-base-dev gfortran python3-setuptools
8 sudo pip3 install https://github.com/lhelontra/tensorflow-on-arm/releases/download/v1.8.0/tensorflow-1.8.0-cp35-none-linux_armv7l.whl
10 sudo apt-get install python3-h5py
11 sudo pip3 install keras==2.1.6

画像判別サンプル

12 git clone https://github.com/karaage0703/keras-pi
13 cd keras-pi

テスト用のカメラ画像を用いて判別（１）

14 python3 pred.py -l ./model/labels.txt -m ./model/mnist_deep_model.json -w ./model/weights.99.hdf5 -t ./data/test.jpg

次のエラーで撃沈

RuntimeError: module compiled against API version 0xc but this version
of numpy is 0xb
RuntimeError: module compiled against API version 0xc but this version
of numpy is 0xb
RuntimeError: module compiled against API version 0xc but this version

numpyをアップデートして、再度試す。

15 python3 -c “import jupyter, matplotlib, numpy, scipy, sklearn
16 pip install -U numpy
17 python3 pred.py -l ./model/labels.txt -m ./model/mnist_deep_model.json -w ./model/weights.99.hdf5 -t ./data/test.jpg

同じエラーで撃沈

RuntimeError: module compiled against API version 0xc but this version
of numpy is 0xb
RuntimeError: module compiled against API version 0xc but this version
of numpy is 0xb
RuntimeError: module compiled against API version 0xc but this version
of numpy is 0xb

では、keras==2.1.6にしたら、どうでしょうか？

23 sudo pip3 install keras==2.1.6

結果は同じエラー。
