  整體架構可參考上圖，mlflow可以針對你模型訓練的參數、loss與model進行追蹤與管理的工具，也提供deploy api來對續的部署進行串接。本文將會快速地介紹如何建立一個tracking server，若只是要本地端的試用，直接參考官方文件的quickstart即可。 其架構大致如上圖，client訓練模型可以log參數、loss、把訓練好的模型上傳，參數部分可存到本地端、或資料庫，model需要有文件儲存空間，像是S3、Azure blob、FTP server等等。 Server設定 Conda 環境下安裝 python 套件 pip install mlflow pip install azure-storage-blob pip install mysqlclient 安裝 MYSQL 建立 user create user 'mlflow'@'%' identified by 'chase0024’; Blob 設定環境變數 Windows(cmd) setx AZURE_STORAGE_CONNECTION_STRING "<yourconnectionstring>" setx AZURE_STORAGE_ACCESS_KEY "<youraccesskey>" Linux(bash) export AZURE_STORAGE_CONNECTION_STRING="<yourconnectionstring>" export AZURE_STORAGE_ACCESS_KEY "<youraccesskey>" 啟動 Server mlflow server --backend-store-uri mysql://dbname:password@127.0.0.1:3306/mlflow --default-artifact-root wasbs://containername@blobaccount.blob.core.windows.net/ --host=0.0.0.0   Client設定 Conda 環境下安...
