1. windows系统解决方案，powershell执行下面的脚本

while ($true) {
    $modelExists = ollama list | Select-String "deepseek-r1:8b"
    if ($modelExists) {
        Write-Host "model is ready"
        break
    }


    Write-Host "download..."
    $process = Start-Process -FilePath "ollama" -ArgumentList "run", "deepseek-r1:8b" -PassThru -NoNewWindow

    Start-Sleep -Seconds 60

    try {
        Stop-Process -Id $process.Id -Force -ErrorAction Stop
        Write-Host "kill and restart..."
    }
    catch {
        Write-Host "error"
    }
}

2.Linux 或 Mac 可使用如下 Shell 脚本

#!/bin/bash

MODEL_NAME="deepseek-coder-v2:16b"

while true; do
MODEL_EXISTS=$(ollama list | grep "$MODEL_NAME")
if [ -n "$MODEL_EXISTS" ]; then
echo "The model $MODEL_NAME is downloaded."
exit 0
fi

ollama run "$MODEL_NAME" &
PID=$!
sleep 120

kill $PID

sleep 3
done
