我想在aarch64(Ubuntu 16.04; Linux on DeX)上安装Tensorflow。

尝试1:按照与经典x86_64体系结构相同的步骤进行操作(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'


与尝试1相关的帖子,但对于Windows是this here。也有人找到其他文章(标题相似),但似乎都没有涉及ARM体系结构。

尝试2:跟随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,我尝试遵循these instructions,但是
无法从here步骤2中安装Bazel失败,因为没有aarch64版本(即使下载了.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,而python3 --version显示3.5.2

更新资料

我尝试了hoefling关于尝试1的建议。在pip3 install tensorflow --extra-index-url=https://www.piwheels.org/simple之前运行pip3 install --upgrade tensorflow使后者工作时没有明显的错误,但是启动python3并使用import tensorflow as tf仍然可以获得较大的回溯输出:

During handling of the above exception, another exception occurred:

最佳答案

我在https://github.com/lhelontra/tensorflow-on-arm/issues/13上发现了问题。简而言之,我在aarch64下缺少某些预备知识。解决方法如下:

# 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))
