树莓派4B安装Tensorflow的方法步骤

1.写作背景

Tensorflow官方在2018年宣布，正式发布支持树莓派版本的Tensorflow，编者开始直接用：

pip install tensorflow

进行安装，在安装成功后使用import进行验证时:

import tensorflow as tf

出现了如下所示报错：

E tensorflow/core/platform/hadoop/hadoop_file_system.cc:132] HadoopFileSystem load error: libhdfs.so: cannot open shared object file: No such file or directory

在花费了大量时间查询资料后，最终得到的解决，故做一个记录。

2.开始前的系统环境与设备

设备：树莓派4B一枚

系统：Raspberry PI OS 2020-5-27版

3.安装过程

Python 3.x + Tensorflow v1 系列

（1）安装必要的依赖项

$ 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 openmpi-bin libopenmpi-dev libatlas-base-dev python3-dev

(2) 安装相关python包

$ sudo pip install keras_applications==1.0.8 --no-deps
$ sudo pip install keras_preprocessing==1.1.0 --no-deps
$ sudo pip install h5py==2.9.0
$ sudo pip install pybind11
$ pip install -U --user six wheel mock

(3)如果之前安装过tensorflow，卸载

$ sudo pip3 uninstall tensorflow

(4)下载Tensorflow

传送门1tensorflow-on-arm

传送门2Tensorflow-bin

选择你要的版本，我选择传送门2的tensorflow-1.15.0-cp37-cp37m-linux_armv7l.whl

$ wget https://github.com/PINTO0309/Tensorflow-bin/raw/master/tensorflow-1.15.0-cp37-cp37m-linux_armv7l.whl

$ sudo pip install tensorflow-1.15.0-cp37-cp37m-linux_armv7l.whl

（4）验证安装是否成功

安装成功后重启终端，运行Python后输入

>>import tensorflow as tf
>>tf.__version__

应该没有报错且正常输出版本信息。

Python 3.x + Tensorflow v2 系列

Tensorflow2系列的安装过程与1系列类似，不再赘述，直接上过程：

$ 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
$ wget "https://raw.githubusercontent.com/PINTO0309/Tensorflow-bin/master/tensorflow-2.2.0-cp37-cp37m-linux_armv7l_download.sh"
$ ./tensorflow-2.2.0-cp37-cp37m-linux_armv7l_download.sh
$ sudo pip3 uninstall tensorflow
$ sudo -H pip3 install tensorflow-2.2.0-cp37-cp37m-linux_armv7l.whl
