How to get Pytorch Working in Fedora 40 with WSL2

Install WSL2: Ensure you have WSL2 installed and set up on your Windows machine. You can follow the official Microsoft guide to install WSL2.

Install Fedora 40: If you haven’t already installed Fedora 40, you can do so using the following command:

wsl --install -d fedora

Enable Systemd: By default, WSL2 doesn’t use systemd. However, you can enable it with some modifications.

sudo dnf install -y systemd systemd-sysv systemd-libs

Create a Script to Launch Systemd: Create a script that will start systemd when your WSL2 session starts. You can name this script start-systemd.sh.

#!/bin/bash
export WSL_DISTRO_NAME=$(basename $(cat /etc/os-release | grep '^NAME=' | cut -d '"' -f 2))
if [ "$WSL_DISTRO_NAME" == "Fedora" ]; then
  exec sudo /usr/sbin/init
fi

Make the script executable:

sudo chmod +x /usr/local/bin/start-systemd.sh

To get to your %UserProfile% directory, in PowerShell, use cd ~ to access your home directory (which is typically your user profile, C:\Users\<UserName>) or you can open Windows File Explorer and enter %UserProfile% in the address bar. The directory path should look something like: C:\Users\<UserName>\.wslconfig.

in the WSL config, run these configurations:

[wsl2]
guiApplications=false
systemd=true

Step 2: Setup Systemd in Fedora on WSL2

Create a Systemd ScriptOpen your Fedora WSL2 terminal and create a script to start systemd:

sudo nano /usr/sbin/enter-systemd-namespace

Add the following content to the script:

#!/bin/bash

if test -n "$WSL_INTEROP"; then
    export WSL_INTEROP
    /usr/bin/nsenter -m -u -i -n -p -t 1 sudo /usr/sbin/init
fi

exec /usr/bin/nsenter -m -u -i -n -p -t 1 "$@"

Save and close the file.

Make the Script Executable

Make the script executable:

sudo chmod +x /usr/sbin/enter-systemd-namespace

Modify your Shell configuration

if test -z "$WINDOWS_PATH"; then
    WINDOWS_PATH=$(wslpath "$(wslvar PATH)")
fi

alias sudo='sudo env "PATH=$WINDOWS_PATH"'
alias systemctl="sudo /usr/sbin/enter-systemd-namespace systemctl"

Source your shell configuration to apply the changes:

source ~/.bashrc

Install Cockpit and its dependencies:

sudo dnf install -y cockpit cockpit-podman

sudo /usr/sbin/enter-systemd-namespace systemctl enable --now cockpit.socket

Open a Web Browser

Open a web browser and navigate to http://localhost:9090. You might need to replace localhost with your WSL2 instance’s IP address if accessing it from another machine.
