    "  - Narzędzie podobne do omawianego na poprzednich zajęciach Sacred\n",
    "  - Nieco inne podejście: mniej ingerencji w istniejący kod\n",
    "  - Bardziej kompleksowe rozwiązanie: 4 komponenty, pierwszy z nich ma funkcjonalność podobną do Sacred\n",
    "  - Działa \"z każdym\" językiem. A tak naprawdę: Python, R, Java + CLI API + REST API\n",
    "  - Popularna wśród pracodawców - wyniki wyszukiwania ofert pracy: 20 ofert (https://pl.indeed.com/), 36 ofert (linkedin). Sacred: 0\n",
    "  - Integracja z licznymi bibliotekami / chmurami\n",
    "  - Rozwiązanie OpenSource, stworzone przez firmę Databricks\n",
    "  - Dostępna [odpłatna wersja \"Managed\"](https://databricks.com/product/managed-mlflow) (w ordóżnieniu od \"self-hosted\")\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."
