如何在 Google Colab 上安装以前版本的 Tensorflow？

Question

!pip uninstall tensorflow -y我通过使用然后卸载了 Google Colab 上预装的 Tensorflow 版本!pip uninstall tensorflow-gpu -y。然后我安装了我想要的版本!pip install tensorflow-gpu==1.4.1，它似乎可以工作并且输出Successfully installed tensorflow-gpu-1.4.1。但是，当我运行时!pip show tensorflow，我收到警告：未找到软件包：tensorflow。

我已经尝试在安装 Tensorflow 后重新启动运行时，但这不起作用。我还运行 GPU 运行时。

另外，当我跑步时：

import tensorflow as tf print(tf.__version__)

我收到以下错误：

如何解决这个问题以正确安装 Tensorflow 1.4.1？我已经尝试在安装 Tensorflow 后重新启动运行时，但这不起作用。我还运行 GPU 运行时。

Answer 1

尝试使用以下命令重新安装tensorflow

!pip uninstall tensorflow -y
!pip install  tensorflow==1.14

然后在 colab 中询问时重新启动运行时。您应该能够导入正确版本的 TensorFlow。

%tensorflow_version 1.x
import tensorflow as tf
print(tf.__version__)

1.14.0
