ARM64 aarch64 3399开发板等 安装新版tensorflow,解决版本不兼容问题
由于目前的TensorFlow版本比较老旧导致很多算法和语法不通用编译报错,且没有几个贴详细说明如何在arm64上安装TensorFlow。
---from中山
注意,安装的过程中会自动下载必须的包,需要连接好网络。脱机安装很可能失败。
1.安装必要的python环境
sudo apt-get install libpython3.5-dev wget python3-pip python3-dev python3.5
2.下载和安装别人编译好的arm(aarch64)版本tensorflow(因为自己编译需要配大量环境和占用很多资源,对于嵌入式板上编译就变得非常不可能,且现有的方法更为简便)
网上有别人编译好的TensorFlow,找到相应的文件。https://github.com/lhelontra/tensorflow-on-arm/releases
#使用wget下载tensorflow-1.9.0-cp35-none-linux_aarch64.whl到当前目录
#命名规则:cp35对赢python3.5,aarch64表示架构信息
wget https://github.com/lhelontra/tensorflow-on-arm/releases/download/v1.9.0/tensorflow-1.9.0-cp35-none-linux_aarch64.whl
#必须制定使用python3.5安装tensorflow-1.9.0-cp35-none-linux_aarch64.whl
sudo python3.5 -m pip install tensorflow-1.9.0-cp35-none-linux_aarch64.whl
到此为止,TensorFlow已经安装完成了
3.修改python默认为python3.5
为了因为C++调用python时,默认是调用python2.7,这导致很多python3.5的语法报错。所以需要更改python默认软连接
查看路径python,python3.5路径
aaa@qq.com#: which python python3.5
/usr/bin/python
/usr/bin/python3.5
aaa@qq.com#:rm /usr/bin/python
#创建python3.5软连接到python
aaa@qq.com#: ln -s /usr/bin/python3.5 /usr/bin/python
测试调用一下:
aaa@qq.com:~/opencv-3-2$ python
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow as tf
>>> hello = tf.constant('Hello world!')
>>> sess = tf.Session()
>>> print(sess.run(hello))
b'Hello world!'
4.出现的错误
有时候可能会出现缺少库额问题 bstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by /usr/local/lib/python3.5/dist-packages/tensorflow/python/_pywrap_tensorflow_internal.so
