如何降级cuda版本 [英] How to do downgrading cuda version

问题描述

我目前使用的是cuda版本4.2，但我需要将其更改为3.1。是否可以卸载当前版本（ver 4.2），然后安装以前的版本（ver 3.1）？

I'm currently using the cuda version 4.2 but I need to change it to 3.1. Is it possible to uninstall the current version (ver 4.2) and then install the previous version (ver 3.1) ?

编辑：请参考我的os系统是linux ubuntu 10.04 64位。

EDIT : Please refer that my os system is linux ubuntu 10.04 64bit.

编辑：我找到了如何获得3.1的版本。我必须发送电子邮件到[e-mail]以请求这个旧版本。现在，请让我知道如何卸载4.2然后安装3.1。

EDIT : I found how to get the version of 3.1. I have to send e-mail to "[e-mail]" to request this old version. Now, please let me know how to uninstall 4.2 then install 3.1.

编辑：我下载cuda 3.1通过请求nvidia，然后安装工具包和SDK。当安装cuda 3.1工具包有关于卸载当前版本的问题。对于SDK，我们可以直接删除〜/ NVIDIA_GPU_Computing_SDK目录，以卸载它。删除后，我可以安装cuda 3.1 SDK。

EDIT : I downloaded cuda 3.1 by request to nvidia, then installed toolkit and SDK. When install the cuda 3.1 toolkit there comes the question about uninstallation of current version. For SDK, we can just delete ~/NVIDIA_GPU_Computing_SDK directory directly for the uninstallation of it. After deleting I could install the cuda 3.1 SDK. I'm done, thanks all.

推荐答案

是的，如果您没有使用CUDA，您可以轻松地降级CUDA版本

Yes, you can easily downgrade the CUDA version provided you aren't using the CUDA toolkit functions which are only present in version greater than 3.1.

此外，您必须修改项目设置以使用CUDA规则版本3.1。

Also you would have to modify your project settings to use CUDA Rules version 3.1.
