Access a compute instance terminal in your workspace

Access the terminal of a compute instance in your workspace to:

• Use files from Git and version files. These files are stored in your workspace file system, not restricted to a single compute instance.
• Install packages on the compute instance.
• Create extra kernels on the compute instance.

Prerequisites

• An Azure subscription. If you don't have an Azure subscription, create a free account before you begin.
• A Machine Learning workspace. See Create workspace resources.

Access a terminal

To access the terminal:

1. Open your workspace in Azure Machine Learning studio.

2. On the left side, select Notebooks.

3. Select the Open terminal image.

   

4. When a compute instance is running, the terminal window for that compute instance appears.

5. When no compute instance is running, use the Compute section on the right to start or create a compute instance.

In addition to the steps above, you can also access the terminal from:

• RStudio or Posit Workbench (formerly RStudio Workbench) (See Add custom applications such as RStudio or Posit Workbench)): Select the Terminal tab on top left.
• Jupyter Lab: Select the Terminal tile under the Other heading in the Launcher tab.
• Jupyter: Select New>Terminal on top right in the Files tab.
• SSH to the machine, if you enabled SSH access when the compute instance was created.

Copy and paste in the terminal

• Windows: Ctrl-Insert to copy and use Ctrl-Shift-v or Shift-Insert to paste.
• Mac OS: Cmd-c to copy and Cmd-v to paste.
• FireFox/IE may not support clipboard permissions properly.

Use files from Git and version files

Access all Git operations from the terminal. All Git files and folders will be stored in your workspace file system. This storage allows you to use these files from any compute instance in your workspace.

Note

Add your files and folders anywhere under the ~/cloudfiles/code/Users folder so they will be visible in all your Jupyter environments.

To integrate Git with your Azure Machine Learning workspace, see Git integration for Azure Machine Learning.

Install packages

Install packages from a terminal window. Install Python packages into the Python 3.8 - AzureML environment. Install R packages into the R environment.

Or you can install packages directly in Jupyter Notebook, RStudio, or Posit Workbench (formerly RStudio Workbench):

• RStudio or Posit Workbench(see Add custom applications such as RStudio or Posit Workbench): Use the Packages tab on the bottom right, or the Console tab on the top left.
• Python: Add install code and execute in a Jupyter Notebook cell.

Note

For package management within a notebook, use %pip or %conda magic functions to automatically install packages into the currently-running kernel, rather than !pip or !conda which refers to all packages (including packages outside the currently-running kernel)

Add new kernels

Warning

While customizing the compute instance, make sure you do not delete the azureml_py36 or azureml_py38 conda environments. Also do not delete Python 3.6 - AzureML or Python 3.8 - AzureML kernels. These are needed for Jupyter/JupyterLab functionality.

To add a new Jupyter kernel to the compute instance:

1. Use the terminal window to create a new environment. For example, the code below creates newenv:

   conda create --name newenv
   

2. Activate the environment. For example, after creating newenv:

   conda activate newenv
   

3. Install pip and ipykernel package to the new environment and create a kernel for that conda env

   conda install pip
   conda install ipykernel
   python -m ipykernel install --user --name newenv --display-name "Python (newenv)"
   

Any of the available Jupyter Kernels can be installed.

Remove added kernels

Warning

While customizing the compute instance, make sure you do not delete the azureml_py36 or azureml_py38 conda environments. Also do not delete Python 3.6 - AzureML or Python 3.8 - AzureML kernels. These are needed for Jupyter/JupyterLab functionality.

To remove an added Jupyter kernel from the compute instance, you must remove the kernelspec, and (optionally) the conda environment. You can also choose to keep the conda environment. You must remove the kernelspec, or your kernel will still be selectable and cause unexpected behavior.

To remove the kernelspec:

1. Use the terminal window to list and find the kernelspec:

   jupyter kernelspec list
   

2. Remove the kernelspec, replacing UNWANTED_KERNEL with the kernel you'd like to remove:

   jupyter kernelspec uninstall UNWANTED_KERNEL
   

To also remove the conda environment:

1. Use the terminal window to list and find the conda environment:

   conda env list
   

2. Remove the conda environment, replacing ENV_NAME with the conda environment you'd like to remove:

   conda env remove -n ENV_NAME
   

Upon refresh, the kernel list in your notebooks view should reflect the changes you have made.

Manage terminal sessions

Terminal sessions can stay active if terminal tabs are not properly closed. Too many active terminal sessions can impact the performance of your compute instance.

Select Manage active sessions in the terminal toolbar to see a list of all active terminal sessions and shut down the sessions you no longer need.

Learn more about how to manage sessions running on your compute at Managing notebook and terminal sessions.

Warning

Make sure you close any sessions you no longer need to preserve your compute instance's resources and optimize your performance.
