Visual Studio Code Extensions for Python¶

Start Visual Studio Code on your host computer.
Connect to your SDK build environment.
Open the folder of a Python sample under samples-python/
Install the extension 'Python from Microsoft': Install in SSH:...

Working with a Python Sample Project¶

From the main menu click File --> Open Folder and select the folder of your desired Python project.
Start a bash terminal within the main menu item - Terminal - New Terminal.
Install or upgrade the ctrlX Data Layer build and runtime environment.

sudo dpkg -i ../..deb/ctrlx-datalayer*.deb

Install a Virtual Environment¶

We recommend to create and activate a virtual Python environment for your project. Furthermore all required packages have to be installed.

Call this script from the command line:

./install-venv.sh

The script runs following commands:

virtualenv -p python3 venv
source venv/bin/activate
pip3 install -r requirements.txt

A subfolder venv/ will be created and activated as virtual environment which contains the Python runtime and all required packages.

Hints: The terminal console path begins with (venv). With Ctrl+Shift+P open the "Command Palette..." and select "Python: Select Interpreter", then 'venv/bin/python' from the virtual environment.

Debugging with Visual Studio Code¶

Open main.py
Select the Python interpreter: Shift+Ctrl+P --> Select 'Python ... ('venv':venv) ... Recommended' *)
Set a breakpoint to the first code line e.g. import ...
Press F5 (Start Debugging)

*) Click update icon if 'Python ... ('venv':venv) ... Recommended' doesn't appear.

Troubleshooting¶

Enable SSH access to your ctrlX CORE.
Watch trace of your snap on the ctrlX CORE e.g.: $ sudo snap logs -f sdk-py-provider-alldata
Debugging Python code on the ctrlX CORE is described here Remote Debugging Python.
