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 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.

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.
