Setting up PyCharm¶
Note: This documentation is based onKedro 0.14.2
, if you spot anything that is incorrect then please create an issue or pull request.
This section will present a quick guide on how to configure PyCharm as a development environment for working on Kedro projects.
Open a new project directory in PyCharm. You will need to add your Project Interpreter, so go to PyCharm | Preferences for macOS or File | Settings for Windows and Linux:
Choose Project Interpreter:
Click the cog on the right-hand side and click Add:
Select Conda Environment:
Choose Existing environment and navigate your way to find your existing environment. If you don’t see your conda
environment in the dropdown menu then you need to open a terminal
/ command prompt
with your conda
environment activated and run:
# macOS / Linux
which python
# Windows
python -c 'import sys; print(sys.executable)'
Paste the interpreter path into the file picker and click OK:
Finally, in the Project Explorer right-click on src
and then go to Mark Directory as | Sources Root:
Set up Run configurations¶
PyCharm Run configurations allow you to execute preconfigured scripts rapidly in your IDE with a click of a button. This may be useful for testing, running and packaging your Kedro projects.
Here we will walk you through an example of how to setup Run configuration for Kedro CLI run
command, however it is also applicable to other Kedro commands: test
, install
, package
, build-docs
.
Go to Run | Edit Configurations:
Add a new Python Run configuration:
Create a Run / Debug Configuration for kedro run
and get the path to the Kedro CLI script:
# macOS / Linux
which kedro
# Windows (in `cmd`)
python -c 'import sys, os.path; print(os.path.join(os.path.dirname(sys.executable), "kedro"))'
Edit the new Run configuration as follows:
Replace Script path with path obtained above and Working directory with the path of your project directory and then click OK.
To execute the Run configuration, select it from the Run / Debug Configurations dropdown in the toolbar (if that toolbar is not visible, you can enable it by going to View > Toolbar). Click the green triangle:
You may also select Run from the toolbar and execute from there.
For other kedro
commands, follow same steps but replace run
in the Parameters
field with the other commands that are to be used (e.g., test
, package
, build-docs
etc.).
Debugging¶
To debug, simply click the line number in the source where you want execution to break:
Then click the bug button in the toolbar () and execution should stop at the breakpoint:
For more information about debugging with PyCharm take a look at the debugging guide on jetbrains.com.
Advanced: Remote SSH interpreter¶
Note: This section uses the features supported in PyCharm Professional Edition only.
Firstly, add an SSH interpreter. Go to Preferences | Project Interpreter as above and proceed to add a new interpreter. Select SSH Interpreter and fill in details of the remote computer:
Click Next and add the SSH password or SSH private key:
Click Next and add the path of the remote interpreter. Assuming a Unix-like OS, this can be found by running which python
within the appropriate conda
environment on the remote computer.
Click Finish. Go to Run / Debug Configurations to add a Remote Run. Select the remote interpreter that you have just created. For the script path, get the path of the Kedro CLI on the remote computer by running which kedro
(macOS / Linux) in the appropriate environment.
Click OK and then select Remote Run from the toolbar and click Run to execute remotely.
To remotely debug, click the debugger button as described above.
