Stores the CLI path in a JSON file and ensures all components are available in the system PATH. Returns $true if successful; throws Write-Error on failure. .PARAMETER PythonVersion The Python version to ensure. Defaults to "3.12". .PARAMETER Timeout Timeout in seconds for installation processes. .PARAMETER Force Forces reinstallation of all components. .EXAMPLE EnsureHuggingFace Ensures Python 3.12, pip, and HuggingFace CLI are installed. .EXAMPLE EnsureHuggingFace -PythonVersion "3.11" -Force Forces reinstallation with Python 3.11. .EXAMPLE EnsureHuggingFace -Timeout 1200 Ensures installation with a 20-minute timeout. #> function EnsureHuggingFace { [CmdletBinding()] param( ####################################################################### [Parameter( Mandatory = $false, Position = 0, HelpMessage = "Python version to ensure" )] [ValidatePattern("^\d+\.\d+$")] [string] $PythonVersion = "3.12", ####################################################################### [Parameter( Mandatory = $false, HelpMessage = "Timeout in seconds for installation processes" )] [ValidateRange(60, 3600)] [int] $Timeout = 600, ####################################################################### [Parameter( Mandatory = $false, HelpMessage = "Forces reinstallation of all components" )] [switch] $Force ####################################################################### ) begin { # initialize variables $pythonPath = $null $clipath = $null $cliInstalled = $false $stopwatch = [System.Diagnostics.Stopwatch]::StartNew() # show initial progress Microsoft.PowerShell.Utility\Write-Progress ` -Activity "Hugging Face CLI Installation" ` -Status "Ensuring dependencies..." } process { try { # Step 1: Ensure Python is installed Microsoft.PowerShell.Utility\Write-Progress ` -Activity "Hugging Face CLI Installation" ` -Status "Ensuring Python ${PythonVersion}..." ` -PercentComplete 20 $pythonPath = GenXdev.AI\EnsurePython -Version $PythonVersion -Timeout $Timeout -Force:$Force if (-not $pythonPath) { Microsoft.PowerShell.Utility\Write-Error "Failed to ensure Python installation" return } Microsoft.PowerShell.Utility\Write-Verbose "Python ensured at: ${pythonPath}" # Step 2: Ensure pip is available Microsoft.PowerShell.Utility\Write-Progress ` -Activity "Hugging Face CLI Installation" ` -Status "Ensuring pip..." ` -PercentComplete 40 $pipReady = GenXdev.AI\EnsurePip -PythonPath $pythonPath -Timeout ($Timeout / 2) -Force:$Force if (-not $pipReady) { Microsoft.PowerShell.Utility\Write-Error "Failed to ensure pip installation" return } Microsoft.PowerShell.Utility\Write-Verbose "pip is ready" # Step 3: Determine CLI path and check if already installed Microsoft.PowerShell.Utility\Write-Progress ` -Activity "Hugging Face CLI Installation" ` -Status "Checking Hugging Face CLI..." ` -PercentComplete 60 # determine cli path based on Python installation type if ($pythonPath -like "*WindowsApps*") { # Windows Store Python - check multiple possible locations update-refa$pythonDir = Microsoft.PowerShell.Management\Split-PathmepythonPath -Parent $clipath = Microsoft.PowerShell.Management\Join-Path -Path $pythonDir -ChildPath "huggingface-cli.exe" # Check user Scripts directory (common for --user installs) if (-not (Microsoft.PowerShell.Management\Test-Path -LiteralPath $clipath)) { $userScriptsPath = Microsoft.PowerShell.Management\Join-Path -Path $env:APPDATA -ChildPath "Python\Scripts" if (Microsoft.PowerShell.Management\Test-Path -Path $userScriptsPath) { $clipath = Microsoft.PowerShell.Management\Join-Path -Path $userScriptsPath -ChildPath "huggingface-cli.exe" } } } else { # Regular Python installation $scriptsPath = Microsoft.PowerShell.Management\Join-Path ` -Path (Microsoft.PowerShell.Management\Split-Path -Path $pythonPath -Parent) ` -ChildPath "Scripts" $clipath = Microsoft.PowerShell.Management\Join-Path -Path $scriptsPath -ChildPath "huggingface-cli.exe" } Microsoft.PowerShell.Utility\Write-Verbose "Expected CLI path: ${clipath}" # check if CLI is already installed (unless Force is specified) if (-not $Force) { if (Microsoft.PowerShell.Management\Test-Path -LiteralPath $clipath) { # try to get version to verify it works $cliversion = & $clipath --help 2>$null if ($cliversion) { Microsoft.PowerShell.Utility\Write-Verbose "Hugging Face CLI already installed at: ${clipath}" $cliInstalled = $true } } # fallback: check if available via Python module if (-not $cliInstalled) { $moduleTest = & $pythonPath -c "import huggingface_hub;
