Offline installation for Machine Learning Server for Windows

  • Artículo

Important

This content is being retired and may not be updated in the future. The support for Machine Learning Server will end on July 1, 2022. For more information, see What's happening to Machine Learning Server?

Applies to: Machine Learning Server 9.2.1 | 9.3 | 9.4

By default, installers connect to Microsoft download sites to get required and updated components for Machine Learning Server for Windows. If firewall constraints prevent the installer from reaching these sites, you can use an internet-connected device to download files, transfer files to an offline server, and then run setup.

Before you start, review the following article for requirements and general information about setup: Install Machine Learning Server on Windows.

9.4.7 Downloads

On an internet-connected computer, download all of the following files.

Component Download Used for
Machine Learning Server setup Get Machine Learning Server for Windows (en_machine_learning_server_for_windows_x64_.zip) from Volume Licensing Service Center (VLSC) ML Server
MLM MLM_9.4.7.0_1033.cab Pre-trained models, R or Python
Microsoft R Open SRO_3.5.2.0_1033.cab R
Microsoft Python Open SPO_4.5.12.0_1033.cab (see note below) Python
Microsoft Python Server SPS_9.4.7.0_1033.cab Python
Python script Install-PyForMLS Python

Note

If you are performing offline installation using the Python script Install-PyForMLS.ps1, then after you download SPO_4.5.12.0_1033.cab, rename the file to SPO_9.4.7.0_1033.cab. The installation script expects this filename.

9.3.0 Downloads

On an internet-connected computer, download all of the following files.

Transfer and place files

Use a tool or device to transfer the files to the offline server.

  1. Put the unzipped en_machine_learning_server_for_windows_x64_.zip file in a convenient folder.
  2. Right-click Extract All to unpack the file. You should see a folder named MLS93Win. This folder contains ServerSetup.exe.
  3. Put the CAB files in the setup user's temp folder: C:\Users<user-name>\AppData\Local\Temp.

Tip

On the offline server, run ServerSetup.exe /offline from the command line to get links for the .cab files used during installation. The list of .cab files appears in the installation wizard, after you select which components to install.

Run setup

After files are placed, use the wizard or run setup from the command line:

Check log files

If there are errors during Setup, check the log files located in the system temp directory. An easy way to get there is typing %temp% as a Run command or search operation in Windows. If you installed all components, your log file list looks similar to this screenshot:

Machine Learning Server setup log files

Set environment variables

Create an MKL_CBWR environment variable to ensure consistent output from Intel Math Kernel Library (MKL) calculations.

  1. In Control Panel, click System and Security > System > Advanced System Settings > Environment Variables.

  2. Create a new User or System variable.

  • Set variable name to MKL_CBWR
  • Set the variable value to AUTO

This step requires a server restart.

Connect and validate

Machine Learning Server executes on demand as R Server or as a Python application. As a verification step, connect to each application and run a script or function.

For R

R Server runs as a background process, as Microsoft ML Server Engine in Task Manager. Server startup occurs when a client application like Rgui.exe connects to the server.

  1. Go to C:\Program Files\Microsoft\ML Server\R_SERVER\bin\x64.
  2. Double-click Rgui.exe to start the R Console application.
  3. At the command line, type search() to show preloaded objects, including the RevoScaleR package.
  4. Type print(Revo.version) to show the software version.
  5. Type rxSummary(~., iris) to return summary statistics on the built-in iris sample dataset. The rxSummary function is from RevoScaleR.

For Python

Python runs when you execute a .py script or run commands in a Python console window.

  1. Go to C:\Program Files\Microsoft\ML Server\PYTHON_SERVER.

  2. Double-click Python.exe.

  3. At the command line, type help() to open interactive help.

  4. Type revoscalepy at the help prompt, followed by microsoftml to print the function list for each module.

  5. Paste in the following revoscalepy script to return summary statistics from the built-in AirlineDemo demo data:

    import os
import revoscalepy 
sample_data_path = revoscalepy.RxOptions.get_option("sampleDataDir")
ds = revoscalepy.RxXdfData(os.path.join(sample_data_path, "AirlineDemoSmall.xdf"))
summary = revoscalepy.rx_summary("ArrDelay+DayOfWeek", ds)  
print(summary)

    Output from the sample dataset should look similar to the following:

    Summary Statistics Results for: ArrDelay+DayOfWeek
File name: /opt/microsoft/mlserver/9.4.0/libraries/PythonServer/revoscalepy/data/sample_data/AirlineDemoSmall.xdf
Number of valid observations: 600000.0

Verify CLI

Note

Before you continue, reboot the machine.

  1. Open an Administrator command prompt.

  2. Enter the following command to check availability of the CLI: az ml admin --help. If you receive the following error: az: error argument _command_package: invalid choice: ml, follow the instructions to re-add the extension to the CLI.
