Set up python development environment 設定Python開發環境

Set up python development environment 設定Python開發環境

1.安裝Visual Studio或Visual Studio Core

https://code.visualstudio.com.

or

https://visualstudio.microsoft.com/

2.安裝Python

install Python from the Microsoft Store

3.確認Python安裝成功

4.啟動Visual Studio Core，安裝Python extension

5.選取 [Python 解譯器]
opening the Command Palette (Ctrl+Shift+P), start typing the command Python: Select Interpreter to search, then select the command

6.第一次啟動Python: Select Interpreter需要一些時間偵測此台主機已安裝的Python環境

7.選擇Python環境

8.在VS Code 終端機執行Python程式
   啟動終端機方法1，Terminal > New Terminal

    啟動終端機方法2，View > Terminal

9.若出現無法辨識conda命令

   輸入python若出現無法辨識python命令

    解決方法: 設定環境變數，在Path變數加入以下兩個路徑
    C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64\Scripts
    C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64

 
    正常啟動終端機的畫面如下

10.執行python，進入Python環境
     輸入印出Hello world的Python程式碼 print("Hello World")

11.測試執行python script檔
   新增一個py檔，並輸入以下Python script
   msg = "Hello World"
   print(msg)
   儲存後，按右鍵選擇[ Run Python File in Terminal]

 
    執行結果如下

SQL Server Machine Learning - Python client:

1.下載PowerShell script安裝Python for SQL Server Machine Learning Service/Server
https://aka.ms/mls93-py
or
https://aka.ms/mls-py

The script installs Anaconda 4.2.0, which includes Python 3.5.2, along with all packages listed previously.
Microsoft Python packages common to both client and server systems include the following:

• revoscalepy
• microsoftml
• azureml-model-management-sdk
• pre-trained models

This article describes how to install a Python interpreter (Anaconda) and Microsoft's Python packages locally on a client machine. Once installed, you can use all of the Python modules in Anaconda, Microsoft's packages, and any third-party packages that are Python 3.5 compliant. For remote compute context, you can only call the Python functions from packages in the above list.

2.若沒有指定安裝路徑，預設安裝在 C:\ProgramFiles\Microsoft\PyForMLS

3.設定環境Path變數
C:\Program Files\Microsoft\PyForMLS

4.IDE開發工具才能偵測到安裝號的Python環境
    Visual Studio Code

    Visual Studio須自訂這個新的Python環境
