Question

我是ML和Colab的新手。尝试在https://github.com/tkarras/progressive_growing_of_gans处玩这个项目，但是很难在Colab中运行它。

当我从项目中运行import_example.py脚本时，我立即收到与未加载Tensorflow有关的错误。因此，我尝试退后一步，只是做import tensorflow as tf。运行此命令时，出现以下错误。我已将运行时设置为GPU。我昨天在Colab演示GPU代码中遇到了同样的问题，但是今天可以正常工作。

有人可以给我任何指示吗？似乎应该在环境中正常工作的基本内容。

Answer 1

即使我也面临同样的问题。后来我意识到我忘了在笔记本设置中启用 GPU 。

我启用了它并安装了 TensorFlow-GPU （GPU版本）。

您可以在编辑> 笔记本设置中找到笔记本设置。

Here's the screenshot

Answer 2

检查是否已在Colab中安装所需的tensorflow版本？（也许您安装了其他版本的tensorflow-gpu，但尚未安装相应的tensorflow版本。在这种情况下，我遇到了相同的错误）

!pip list

如果列表中没有tensorflow，则应同时安装tensorflow和tensorflow-gpu，如下所示：

!pip install tensorflow=='enter version here'
!pip install tensorflow-gpu=='enter same version as the previous one here'

Answer 3

您只需要仔细阅读错误即可：

注意：如果由于缺少软件包而导致导入失败，则可以使用！pip或！apt手动安装依赖项。

尝试运行：

<script 
src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div class="cursor cursor-a"></div>
<div class="cursor cursor-b"><div class="cursor-v"></div></div>

<div class="cont">
   <a class="link" href="#">custom link, hover me!</a>
</div>

在笔记本中，然后使用导入重新运行单元格。

Answer 4

TensorFlow默认包含在Colab中。因此，我怀疑您已经以某种方式破坏了现有安装。

您可以通过选择“运行时->重置所有运行时...”菜单来请求新的后端。然后，再次尝试import tensorflow as tf。

Tensorflow不会在Colab中导入
