我想在 aarch64(Ubuntu 16.04；Linux on DeX)上安装 Tensorflow。
尝试 1:遵循与经典 x86_64 架构相同的程序(在那里工作)；见here
sudo apt update
sudo apt install python3-dev python3-pip virtualenv # the latter was required under aarch64, not under x86_64
sudo -H pip3 install --upgrade virtualenv
mkdir /usr/local/tensorflow
virtualenv --system-site-packages -p python3 /usr/local/tensorflow
source /usr/local/tensorflow/bin/activate
pip3 install --upgrade tensorflow # fails with 'Error: Could not find a version that satisfies the requirement tensorflow (from versions: none)' and 'Error: No matching distribution found for tensorflow'
尝试 1 的相关帖子但适用于 Windows 是 this here .还可以找到其他帖子(类似标题)，但似乎都没有涉及 ARM 体系结构。
尝试 2:关注 these instructions
sudo apt update
sudo apt install python3-dev python3-pip
mkdir /usr/local/tensorflow
cd /usr/local/tensorflow
wget https://github.com/lhelontra/tensorflow-on-arm/releases/download/v1.8.0/tensorflow-1.8.0-cp35-none-linux_aarch64.whl
sudo -H pip3 install tensorflow-1.8.0-cp35-none-linux_aarch64.whl
# => reports 'Failed building wheel for ...'. Still seems to somehow progress
# but then 'import tensorflow as tf' in a Python 3.5.2 session produces a lot
# of traceback output and essentially shows that the installation did not work.
在第三次尝试中，我试图跟随 these instructions但 无法将 Bazel 安装为来自 here 的第 2 步失败，因为没有 aarch64 版本(即使下载 .tar.gz，编译也会失败并显示 ERROR: Must specify PROTOC if not bootstrapping from the distribution artifact...
更多信息:python --version 显示 2.7.12 和 python3 --version 显示 3.5.2
更新
我尝试了 hoefling 对尝试 1 的建议。运行 pip3 install tensorflow --extra-index-url=https://www.piwheels.org/simple就在 pip3 install --upgrade tensorflow 使后者工作没有明显错误之前，但是启动 python3 并使用 import tensorflow as tf 我仍然获得了一个大回溯输出:

请您参考如下方法:
我在 https://github.com/lhelontra/tensorflow-on-arm/issues/13 上发现了这个问题。简而言之，我错过了 aarch64 下的某些准备工作。这是解决方案:
# Preliminaries
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-4.9
sudo apt install --only-upgrade libstdc++6
# Installation similar to Ubuntu on x86_64
sudo apt update
sudo apt install python3-dev python3-pip virtualenv
sudo -H pip3 install --upgrade virtualenv
mkdir /usr/local/tensorflow
virtualenv --system-site-packages -p python3 /usr/local/tensorflow/
source /usr/local/tensorflow/bin/activate
pip3 install --upgrade tensorflow
deactivate
# Test
source /usr/local/tensorflow/bin/activate
$ python3
>>> import tensorflow as tf
>>> hello = tf.constant("Hello, World!")
>>> sess = tf.Session()
>>> print(sess.run(hello))
