How to Upload and Download Data #

You can upload your datasets to the Platform using Neuro CLI. Neuro CLI supports basic file system operations for copying and moving files to and from the Platform storage.

From your terminal or command prompt, change to the directory containing your dataset, and run:

neuro cp -r data/ storage:data/

The URI storage:data/ indicates that the destination is the Platform. In a similar fashion,

neuro cp -r storage:data/ data/

downloads dataset to your current directory locally.

You can access your dataset from within a container by giving --volume storage:data/:/var/storage/data/:rw to neuro run when starting a new job.

How to Browse Data with File Browser #

File Browser is a web-based file management interface. You can use it to view and manage your storage on Neuro Platform. To start the job and open the tool in your default browser, run the following command:

neuro run \ --name filebrowser \ --preset cpu-small \ --http 80 \ --detach \ --browse \ --volume storage::/srv:rw \ filebrowser/filebrowser

File Browser requires logging in; the default credentials are admin/admin. For more complex user setup, please refer to File Browser documentation.

How to Connect to a Running Job #

To work with your dataset from within a container, or to troubleshoot a model, or to get shell access to a GPU instance, you can execute a command shell within a running job in interactive mode.

To do so, copy the job id of a running job (you can run neuro ps to see the list), and run:

neuro exec <job-id or job-name> bash

For example,

neuro exec training bash

This command starts bash within the running job and connects your terminal to it.

How to Run a Job in a Custom Environment #

Assuming you have a local Docker image named helloworld built on your local machine, you can push it into Neuro Platform by running:

neuro push helloworld

After that, you can start the job by running:

neuro run image:helloworld

How to Kill All Running Jobs #

To kill all jobs that are currently running on your behalf, run the following command:

neuro kill `neuro -q ps -o <user>`

For example,

neuro kill `neuro -q ps -o mariyadavydova`

How to Run Two or More Commands In a Job #

Sometimes you want to execute two or three commands in a job without having to connect to it. For example, you may want to change the working directory and to run training. To achieve this, you need to wrap your commands in ”bash -c ‘<commands>’” call, like this:

"bash -c 'cd /project && python mnist/train.py'"

How to Get Output from a Running Job #

There are two ways to get the output of your running job:

  • Run it without --detach option.
  • Connect to a running job output with neuro log <JOB>, where JOB is either an id or a name of your job.

In some cases Python cashes the output of the scripts, so that you won’t get any output until the job finishes. To overcome this problem provide -u option to python, like this:

"bash -c 'cd /project && python -u mnist/train.py'"
