    "  - Działa \"z każdym\" językiem. A tak naprawdę: Python, R, Java + CLI API + REST API\n",

    "## Komponenty\n",
    "\n",
    "MLflow składa się z czterech niezależnych komponentów:\n",
    " - **MLflow Tracking** - pozwala śledzić zmiany parametrów, kodu, środowiska i ich wpływ na metryki. Jest to funkcjonalność bardzo zbliżona do tej, którą zapewnia Sacred\n",
    " - **MLflow Projects** - umożliwia \"pakowanie\" kodu ekserymentów w taki sposób, żeby mogłby być w łatwy sposób zreprodukowane przez innych\n",
    " - **MLflow Models** - ułatwia \"pakowanie\" modeli uczenia maszynowego\n",
    " - **MLflow Registry** - zapewnia centralne miejsce do przechowywania i współdzielenia modeli. Zapewnia narzędzia do wersjonowania i śledzenia pochodzenia tych modeli.\n",
    " \n",
    "Komponenty te mogą być używane razem bądź oddzielnie."
