Question

我正在尝试安装Tensorflow 2.0。这些是我正在运行的命令：

$ pip3 install tensorflow-gpu

当我打开Python控制台（在Jetbrains PyCharm中）

import tensorflow as tf

我立即收到一堆弃用警告：

当我尝试通过以下方式检查Tensorflow的版本时：

tf.__version__

它输出：

'1.14.0'

我是Python的新手，我不确定是什么问题。

Answer 1

python3 -m pip install --upgrade tensorflow-gpu>=2

我真的没有解释为什么它不能正常安装2.0。这些命令之间应该没有任何区别，但是该命令有效而pip3 install却没有。

此外，最好先更新pip本身：

pip3 install --upgrade pip

UPD，根本原因： TF2需要pip19。在大多数情况下，简单的pip升级应该会有所帮助。

此外，在最新版本中，pip3可执行文件已损坏，已通过使用python3 -m pip进行了修复。这个问题已经解决。

pip3 install tensorflow-gpu安装tensorflow版本1.14.0
