安装后找不到火炬模块

Question

我正在尝试在我的 ubuntu 服务器上安装 torch-geometric-temporal。 但我不断遇到错误

ModuleNotFoundError: No module named 'torch'

。 您能给我一个提示，我可以做什么来解决这个错误吗？

以下是我迄今为止执行的步骤：

更新和升级 Ubuntu 20.04.6 LTS

sudo apt update && sudo apt upgrade -y

为我的 Python 3.10.13 设置 venv

python3 -m venv venv

激活venv

source venv/bin/activate

安装火炬和火炬几何时间

pip install torch
pip install torch-geometric-temporal

这是我收到的完整错误消息

Answer 1

看起来

torch

已成功安装在您的虚拟环境 (

venv

) 中，但是当

torch-geometric-temporal

尝试安装时，它在尝试构建轮子时遇到错误，特别是当它获得构建轮子的要求时轮子。

问题可能是

torch-geometric-temporal

依赖于

torch-sparse

，并且可能缺少一些依赖项或安装出现问题。

您可以尝试执行以下几个步骤来解决此问题：

1. 重新安装torch-sparse：尝试手动重新安装

   torch-sparse

   ，看看安装过程中是否有错误。

   pip install torch-sparse --no-build-isolation
   

   --no-build-isolation

   标志可以帮助安装过程访问可能丢失的系统级依赖项。

2. 检查是否缺少依赖项：确保您拥有构建所需的所有依赖项

   torch-sparse

   。有关任何特定依赖项，请参阅

   torch-sparse

   或

   torch-geometric-temporal

   的文档。

3. 升级 pip 和 setuptools：有时，此类问题可以通过将

   pip

   和

   setuptools

   升级到最新版本来解决。

   pip install --upgrade pip setuptools
   

4. 检查系统要求：验证您的系统是否满足安装和运行

   torch-geometric-temporal

   及其依赖项的所有要求。

5. 更新系统软件包：确保您的所有系统软件包都是最新的。有时，过时的系统包可能会导致与 Python 包发生冲突。

6.检查Python版本兼容性：确保您使用的Python版本与

torch-geometric-temporal

及其依赖项兼容。

尝试这些步骤，看看是否可以解决问题。如果问题仍然存在，您可能需要提供更多详细信息或查阅文档或支持渠道

torch-geometric-temporal

以获得进一步帮助。
