### Linux ROCm Module Installation and Configuration For the installation of ROCm on a Linux system, particularly focusing on Ubuntu distributions, several key points must be considered to ensure successful setup. The process involves ensuring compatibility between different versions of ROCm and other software components such as CMake. When building RCCL ( Radeon Collective Communications Library ) with ROCm version 3.5, manual installation might become necessary due to specific requirements or issues encountered with earlier versions like ROCm 3.3 which had known problems when used alongside certain tools including an outdated CMake version 3.6[^1]. To proceed correctly: #### Prerequisites Verification Before starting the ROCm installation, verify that the operating system meets all prerequisites. For instance, while newer images may come pre-configured for easier integration with frameworks like PyTorch within environments tailored towards deep learning applications [^3], older systems require careful attention to dependencies and environment configurations. #### Installing ROCm Modules The official documentation recommends installing ROCm through package managers available in supported Linux distributions. However, for offline setups where internet access is restricted, one would need to download packages manually from AMD's website or another trusted source before transferring them onto the target machine. This approach applies especially to isolated networks similar to those described in scenarios involving laboratory servers running older OS releases [^4]. Once downloaded, follow these general steps adjusted according to your exact distribution and version: - Update existing repositories. - Install required kernel headers if not already present. - Add the ROCm repository URL into `/etc/apt/sources.list.d/rocm.list`. - Import GPG keys associated with this new repository. - Execute `apt-get update` followed by `apt-get install rocm-dkms`. After completing the above procedures successfully, rebooting will load the newly installed drivers automatically during startup. #### Post-installation Setup Following driver installation, configuring ROCm entails setting up environment variables properly so that subsequent installations of libraries depending on it can locate essential files without errors. An example includes specifying Python site-packages directories explicitly using paths compatible with installed interpreters [^2]: ```bash export PYTHONPATH=/usr/local/lib/python3.7/site-packages:$PYTHONPATH ``` This command ensures any additional modules added later are accessible globally across sessions after being placed inside designated folders recognized by both ROCm and relevant programming languages utilized throughout development workflows. --related questions-- 1.
