Kubeflow 簡介

Kubeflow 讓使用者能夠透過網頁介面的方式, 簡單的建置一個能夠進行機器學習的環境, 可以直接用已經包裝好的環境進行實驗, 不用再從零開始把一個環境安裝起來。

我們目前的集群內有10台機器, 總共156顆核心和 660GB以及備載GPU運算能力的伺服器。在 Kubeflow上, 使用者可以選擇自己想要的編譯器(目前支援的編譯器:Codeserver、Rstudio以及Jupyterhub),配上需要的機器環境, 以及需要的資源(如:CPU、記憶體、GPU以及儲存容量),就可以進行實驗。


登入教學

以下是服務連結:

申請帳號請至 服務->帳號申請 , 按表單填寫資料, 並選擇Kubeflow 平台, 成功申請後會提供帳號密碼。若需要GPU, 則選擇 Kubeflow(with GPU) 平台。

注意

因為大數據運算平台會有許多使用者共享運算資源,因此不使用時請關閉 notebook 以釋放運算資源,關閉 Notebook 有兩種方式:

  1. 點擊方塊圖示,關閉 notebook 但保留資源配置、掛載的 volume 等設定
  2. 點擊垃圾桶圖示,關閉 notebook 且刪除所有設定

如果沒有要更換編譯環境的話,建議點擊方塊圖示以節省下一次使用時重新設定環境的時間
