Introduction

In this tutorial, you can learn how to set up remote debugging with PyCharm Professional on the Neuro Platform using the Neu.ro project template.

Initializing a new project

First, make sure that you have the Neu.ro CLI client installed and configured:

> pip install -U neuro-cli neuro-flow
> neuro login

Then, initialize an empty project:

> neuro project init

This command will prompt you to enter some info about your project:

project_name [Name of the project]: Neuro PyCharm
project_slug [neuro-pycharm]: 
code_directory [modules]:

Next, switch to the new project's folder and configure the project's environment on the Neuro Platform:

> cd neuro-pycharm 
> neuro-flow build myimage

Setting up PyCharm

Open the project you have just created in PyCharm Professional and add the code you want to debug as a new main.py file (in this example, we use a code snippet from the JetBrains documentation).

Then, you will need to exclude all directories that don't contain Python code (in an empty Neu.ro project, only the modules folder will contain code). PyCharm doesn't synchronize excluded directories. Select all directories to exclude, right-click, and select Mark Directory as -> Excluded. As a result, you will see a configured project:

Run these commands to upload your code to the Neuro Platform storage:

> neuro-flow mkvolumes
> neuro-flow upload ALL

Now, we are ready to start a GPU-powered development job on the Neuro Platform. Run the following command:

> neuro-flow run remote_debug

This command starts a remote_debug job on the Neuro Platform. This job uses the cluster's default preset and forwards the local port 2211 to the job's SSH port. All running jobs consume your quota, so please don't forget to terminate your jobs when they are no longer needed. You can use neuro-flow kill remote_debug to kill the job you created in the previous step or neuro-flow kill ALL to kill all your running jobs.

Then go back to the PyCharm project and navigate to Preferences -> Project -> Project interpreter (you can also search for "interpreter"). Click the gear icon to view the project interpreter options and select Add... In the new window, select SSH Interpreter and set up the following configuration:

• Host: localhost

• Port: 2211

• Username: root

When this is done, click Next.

In the new window, specify the paths for the interpreter and synced folders:

Interpreter: /opt/conda/bin/python
Sync folders: <Project root> -> /neuro-pycharm

Note that, within the job, your project's root folder is available at the root of the filesystem: /{project_name} .

Click Finish, and your configuration is ready:

Click OK.

Once you apply the remote interpreter configuration, PyCharm will start file synchronization.

Your PyCharm project is now configured to work with a remote Python interpreter running in a Neu.ro job.

Debugging

In this example, we're working with the main.py file. To enter debug mode, right-click the file and click Debug 'main':

Now, you can interact with the file in debug mode:
