How to install multiple Tensorflow - CUDA versions on the same machine

As Tensorflow is continuously evolving, it is normal to find a situation in which you require multiple versions of Tensorflow to coexist on the same machine. Those versions can be different enough to have different CUDA library dependencies. In this case, you can be tempted to upgrade to the latest release but maybe some of your solutions are still in production or just there are not more holes in your calendar.

In this gist I will cover how to install several CUDA libraries to support different tensorflow verions. However, there are some red lines that you have to respect as the GCC versions, that must be the same, and the nvidia drivers that must support the target CUDA versions. You can check that information in the Tensoroflow website.

The basic idea is to install the CUDA libraries and abuse of the linux system to find the correct libraries when executing the target tensorflow version

List of Linux Tips

Kill all the process defined by a process name:

ps -aux | grep 'myProcessName' | grep -v grep | awk '{print $2}' | xargs -r kill -9

Check a line from multiple files:

find . -name 'process.sh' | xargs sed -i 's/..\/load_env.sh/modules\/load_env.sh/g'

Install Tensorflow2 with GPU in Ubuntu 24.04

Installation of Tensorflow2 with GPU support is easy and the only complication can be arisen from the CUDA compability which in turns depends on the Nvidia driver version. Before going farther, please check if your Nvidia Video Card is compatible with the required versions that are defined in this gist, use this link.

Tensorflow offers in its website a table of the compatibility between libraries for the target OS. You can visit that website in the following COMPATIBILITY TABLE that points to the Tensorflow installation from source for linux. For the time writing this gist, Tensorflow2 v2.17.0 requires CUDA v12.3 and CUDNN v8.9. As CUDA v12.6 gives support for Ubuntu 24.04, I've replaced CUDA v12.3 with CUDA v12.6, but maintaining CUDNN v8.9. It is really important to match the exact version of CUDNN, otherwise tensorflow will have proble

How to install in windows 10 a linux distribution in dualboot

UEFI mode appearance has made more difficult the dualboot installation of linux in conjunction with windows. This gist is a brief guide to accomplish this goal.

It is assumed that Windows 10 has been installed. First steps before the linux installation is to disable the windows fast start, hibernation mode and hybrid sleep to avoid future problems. Windows fast start must be unchecked from the power options in the control panel under the section 'What power buttons do'. The hibernation must be disabled using a windows command prompt with admin privileges and typing:

*powercfg.exe /h off*

Configure a working environment to easily Deploy your project using Git

This gist explains how to set a working environment to deploy easily your project in your production server. To this aim a git bare repository is set in the remote server which is used for control versions as well as to upload and deploy your progress to the production server.

The structure of the proposed environment consists of 3 parts:

1. Working directory (Local)
2. Deployment directory (Remote Server)
3. Git bare repository (Remote Server)

How to install Tensorflow with CUDNN on Ubuntu Distro 14.04 or higher with CUDA 8.0 and CUDNN 6.0

This gist shows how to install Tensorflow with CUDNN support and how to check the correct installation. This gist is based on the Tensorflow installation guide and following the LearnOpencv blog entry Installing Deep Learning Frameworks on Ubuntu with CUDA support that is more complete that this gist but there are sometimes misleading/hidden steps that can be covered in this gist.

First prerequisite is the CUDA Toolkit installation. You can check this gist for the CUDA installation. As a difference from the CUDA installation CUDNN is very easy to install. We only have to deploy the downloaded libraries in your system. At the time I am writing this guide current toolkit version is 8.0.
