[樹莓] 樹莓派3B+ 安裝Keras

直接下指令pip install keras，會出現keras requires tensorflow 2.2 or higher.

總之要使用keras需要tensorflow 2.2以上的版本。

在此做一下記錄，注意！我是在樹莓派3B+上實作的。

指令安裝tensorflow 2.4.0-cp37-none-linux_armv7l版本：

$ sudo apt-get install -y libhdf5-dev libc-ares-dev libeigen3-dev gcc gfortran python-dev libgfortran5 \
                          libatlas3-base libatlas-base-dev libopenblas-dev libopenblas-base libblas-dev \
                          liblapack-dev cython libatlas-base-dev openmpi-bin libopenmpi-dev python3-dev
$ sudo pip3 install keras_applications==1.0.8 --no-deps
$ sudo pip3 install keras_preprocessing==1.1.0 --no-deps
$ sudo pip3 install h5py==2.9.0
$ sudo pip3 install pybind11
$ pip3 install -U --user six wheel mock

$ pip3 install -U --ignore-installed wrapt enum34 simplejson netaddr （這行不執行會出現：Cannot uninstall 'wrapt'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.）

到此下載：https://github.com/lhelontra/tensorflow-on-arm/releases
（點選tensorflow-2.4.0-cp37-none-linux-armv7l.whl, 或參考資料裡有備份此檔供下載）

$ sudo -H pip3 install tensorflow-2.4.0-cp37-none-linux_armv7l.whl

安裝完tensorflow以後再下指令安裝keras:

sudo pip3 install keras

就可以了

目前import 以下keras的LIB是沒問題的：

import keras

from keras.layers import Dense, Dropout, Input

from keras.models import Model,Sequential

from keras.datasets import mnist

from tqdm import tqdm

from keras.layers.advanced_activations import LeakyReLU

from keras.optimizers import Adam

PS: Adam的A要大寫喔，輸入adam會出錯
