[Unofficial] ROCM Installer TL;DR (see Pre-Install Steps for your OS Distro)

Steps to install/uninstall ROCm (multiple releases side-by-side or single version)

Pre-install step: Upgrade OS to get latest kernel headers, etc.

1. Download amdgpuinst.py script, install ROCm AMDGPU DKMS packages and reboot:

  wget -O amdgpuinst.py --no-cache --no-check-certificate https://raw.githubusercontent.com/srinivamd/rocminstaller/master/amdgpuinst.py

Example: Install ROCm DKMS/kernel packages amdgpu-dkms and amdgpu-dkms-firmware
  sudo python3 ./amdgpuinst.py --rev 5.5.0
  sudo reboot

2. Download rocminstall.py script to install ROCm User Level Packages:

  wget -O rocminstall.py --no-cache --no-check-certificate https://raw.githubusercontent.com/srinivamd/rocminstaller/master/rocminstall.py
Example: Install ROCm [add --nomiopenkernels to exclude pre-built miopenkernels]
  sudo python3 ./rocminstall.py --rev 5.5

UNINSTALL AMDGPU DRIVER

1. To uninstall AMDGPU driver, uninstall amdgpu-core, amdgpu-dkms and amdgpu-dkms-firmware packages and reboot:

On Ubuntu:
   sudo apt remove amdgpu-core amdgpu-dkms amdgpu-dkms-firmware
   sudo reboot
On RHEL, SLES:
   sudo yum remove amdgpu-core amdgpu-dkms amdgpu-dkms-firmware
   sudo reboot

UNINSTALL ROCM

1. To uninstall ROCm, download the rocmuninstall.sh script, run with version or "all":

 wget -O rocmuninstall.sh --no-cache --no-check-certificate https://raw.githubusercontent.com/srinivamd/rocminstaller/master/rocmuninstall.sh

Example: To uninstall ROCm 5.5 packages use (requires sudo):
    sudo sh ./rocmuninstall.sh 5.5.0  [use "all" to uninstall user AND kernel packages]

[Unofficial] V1.62 rocminstall.py Utility to install ROCm releases. Supports Ubuntu/Debian, CentOS/RHEL 7/8, SLES15 installation

NOTE: Install dkms, kernel headers, gcc packages on OS BEFORE installing ROCm Kernel

Section CentOS Pre-Install Steps (Install Perl dependencies)

CentOS 7/8 Preparing System for ROCm Kernel:

  sudo yum clean all
  sudo yum update (this would update kernel to latest. Do this before installing kernel-headers.)
  sudo reboot
  sudo yum install kernel-headers-`uname -r`
  sudo yum install gcc
  sudo yum install gcc-c++
  sudo yum install -y epel-release
  RHEL8:
    sudo subscription-manager repos --enable codeready-builder-for-rhel-8-$(arch)-rpms
    sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
  RHEL9:
    sudo subscription-manager repos --enable codeready-builder-for-rhel-9-$(arch)-rpms
    sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
  RockyLinux9:
    sudo dnf --enablerepo=crb install perl-File-BaseDir
  sudo yum install dkms
  sudo yum install kernel-devel-`uname -r`
  sudo yum install python3
  sudo yum install wget
  sudo yum install git
  sudo yum install perl
  sudo yum install perl-URI-Encode
  sudo reboot (for above updates to take effect)
  NOTE: install devtoolset-7 for CentOS7/RHEL7

To remove ROCm Kernel (amdgpu-dkms amdgpu-dkms-firmware) Packages:

CentOS/RHEL rpm Commands to UNINSTALL amdgpu-dkms amdgpu-dkms-firmware packages FIRST before install

  sudo rpm -evh amdgpu-dkms amdgpu-dkms-firmware (OR sudo rpm -evh --nodeps amdgpu-dkms amdgpu-dkms-firmware)
  sudo reboot

Section: Ubuntu Pre-Install Steps

Ubuntu 18 HWE Preparing System for ROCm Kernel

   sudo apt-get install --install-recommends linux-generic-hwe-18.04  (Use linux-generic-hwe-20.04 for Ubuntu 20.04 HWE.) 
   (Update to LTS HWE before installing linux-headers.)
   sudo reboot
   sudo apt install dkms
   sudo apt install gcc
   sudo apt install g++
   sudo apt upgrade (this may be needed for kernel updates to correspond with headers, etc.)
   sudo reboot (for above upgrade to take effect)
   sudo apt install linux-headers-`uname -r`
   sudo apt install linux-tools-`uname -r`
   sudo reboot

To Update ROCm Kernel (amdgpu-dkms amdgpu-dkms-firmware) Packages:

Ubuntu dpkg Commands to UNINSTALL ROCm amdgpu-dkms amdgpu-dkms-firmware packages FIRST before install

  sudo dpkg -r --force-all amdgpu-dkms amdgpu-dkms-firmware
  sudo dpkg --purge --force-all amdgpu-dkms amdgpu-dkms-firmware
  sudo reboot

NOTE: On SLES15, the script uses zypper and requires user interaction

Section: Install ROCm

Download Python3 rocminstall.py script:

wget -O rocminstall.py --no-cache --no-check-certificate https://raw.githubusercontent.com/srinivamd/rocminstaller/master/rocminstall.py

Example: Install ROCm, including kernel components (assumes dkms, kernel header, gcc preinstalled)
  wget -O rocminstall.py --no-cache --no-check-certificate https://raw.githubusercontent.com/srinivamd/rocminstaller/master/rocminstall.py

Example: Install ROCm, excluding pre-built miopenkernels (faster install)
  sudo python3 ./rocminstall.py --rev 5.5 --nomiopenkernels

Example: Install ROCm including pre-built miopenkernels
  sudo python3 ./rocminstall.py --rev 5.5

Example: Install ROCm packages in container (no kernel components)

Usage

usage: rocminstall.py [-h] [--rev REVSTRING] [--destdir DESTDIR] [--list]
                      [--repourl REPOURL] [--baseurl BASEURL] [--nokernel]
                      [--justkernel] [--justrdc] [--nomiopenkernels]

[V1.62]rocminstall.py: utility to download and install ROCm packages for
specified rev (dkms, kernel headers must be installed, requires sudo
privilege)

optional arguments:
  -h, --help         show this help message and exit
  --rev REVSTRING    specifies ROCm release repo to use as in
                     http://repo.radeon.com/rocm/{apt, yum, zyp,
                     centos8}/<REV> Example: --rev 3.5 for ROCm 3.5 repo
                     http://repo.radeon.com/rocm/{apt, yum, zyp, centos8}/3.5,
                     or --rev 3.3 for ROCm 3.3 repo
                     http://repo.radeon.com/rocm/{apt, yum, zyp}/3.3
  --destdir DESTDIR  specify directory where to download RPM before
                     installation. Default: current directory --destdir /tmp
                     to use /tmp directory
  --list             just list the packages that will be installed -- do not
                     download or install
  --repourl REPOURL  specify ROCm repo URL to use from where to download
                     packages Example: --repourl http://compute-
                     artifactory/build/xyz
  --baseurl BASEURL  specify early access ROCm repo URL to use from where to
                     download packages Example: --baseurl
                     http://repo.radeon.com/rocm/private/apt_3.6-priv/
  --nokernel         do not install amdgpu kernel packages, for example, used to
                     install ROCm in docker
  --justkernel       ONLY install amdgpu kernel packages of specified version -
                     undefined behavior if --nokernel also specified
  --justrdc          ONLY install ROCm Radeon Data Center Monitor tool -
                     attempts to install rdcX.Y.Z package corresponding to rev
  --nomiopenkernels  do not install pre-built miopenkernels packages - saves
                     space and installation time
