Paperspace Python

Project description

Paperspace Python

Release 0.2.0

See for details on the current release, as well as release history.

Getting Started

  1. Make sure you have a Paperspace account set up. Go to to register.

  2. Use pip, pipenv, or conda to install the paperspace-python package, e.g.:

    pip install -U paperspace

    To install/update prerelease (Alpha/Beta) version version of paperspace-python, use:

    pip install -U --pre paperspace

  3. Enable autocomplete:

    Add following to your .bashrc (or .zshrc) to enable autocomplete anytime you activate your shell. If paperspace-python was installed in a virtual environment, the following has to be added to the activate script:

    eval "$(_PAPERSPACE_PYTHON_COMPLETE=source paperspace-python)"

    Alternatively, you can create activation script by:

    (_PAPERSPACE_PYTHON_COMPLETE=source paperspace-python) > ~/

    and then add . ~/ to your .bashrc, .zshrc or activate script.


  4. Download your api key by executing the following:

    paperspace-python login

    Follow the prompts to enter your Paperspace email and password.

    You can also enter your credentials directly on the command line as follows:

    paperspace-python login <email> <password> [<api_token_name>]

    Note: your api key is cached in ~/.paperspace/config.json You can remove your cached api key by executing:

    paperspace-python logout

  5. Run the sample script using Python:


    The source of this sample script shows how a script can automatically run itself on the Paperspace job cluster node:

    import paperspace
    print('hello paperspace-python!')

    Note: the source is modified before transfer to the job cluster in order to remove imported paperspace references.

  6. Use paperspace-python to run a python script remotely:

    paperspace-python run

    The script will be run on the Paperspace job cluster node, and its output will be logged locally.

Create/create and start experiment

To create new experiment use:

paperspace-python experiments create [type] [--options]

The two available experiment types are singlenode and multinode.

To create and immediately start new experiment use:

paperspace-python experiments createAndStart [type] [--options]

For a full list of available commands run paperspace experiments --help. Note that some options are required to create new experiment.

Specifying jobs options within a script

This example shows how a script can specify paperspace jobs options for itself, such as project name, machineType, and a container reference:

# tests/ - runs itself on paperspace, demonstrates setting jobs create options
import os
import paperspace{'project': 'myproject', 'machineType': 'P5000',
                'container': 'paperspace/tensorflow-python'})

print('something useful')

Automatic running of a python script remotely

The above example demonstrates running a python script locally and having that script transmit itself to the paperspace jobs cluster for further execution. To do this a copy of the local script is modified before transmission to the jobs cluster, in order to strip out the import paperspace statements and other paperspace library references. There are also some limitations on the types of import statements that are supported, and the dependencies that are supported in each environment (local vs. remote):

  1. You need to use a bare import statement, import paperspace, and not use the import paperspace as ... form.
  2. The import form from paperspace import ... is currently not supported.
  3. Everything after the function call is ignored when running locally (when no script name is provided). The local script execution stops after the call.
  4. Dependencies that are included before must be available locally.
  5. If you need to reference dependencies that are not available locally but are available remotely, those should be imported after the call.
  6. Dependencies that are needed remotely need to either be already installed in the container used for the job, or need to be installed using one of the techniques below in the section Dependency Options

Because of these limitations it may not always be appropriate to run python scripts automatically from within the same script file. As an alternative you can run your python scripts unmodified using the techniques below.

Running a python script by name

You can run an python script on paperspace from the command line as follows:

paperspace-python run

You can also provide additional jobs options on the command line:

paperspace-python run --project myproject --machineType P5000 \
 --container paperspace/tensorflow-python`

Alternatively you can use the fuction in code with a script file name as the first argument:

import paperspace'') # runs myscript on paperspace

In code you can provide additional paperspace jobs create options in a dict in the second argument to run():'', {'project': 'myproject', 'machineType': 'P5000',
                               'container': 'paperspace/tensorflow-python'})

See the Paperspace API jobs create documentation for the full list of jobs create options that can be specified.

Using paperspace-python run

The paperspace-python run command provides a number of options to run python code and other commands remotely, as well as copy files and set up python dependencies:

paperspace-python run [options] [[-m] <script> [args] | -c "python code" | --command "shell cmd"]
  [--python 2|3]
  [--init [<>]]
  [--req [<requirements.txt>]]
  [--workspace .|<workspace_path>]
  [--ignoreFiles "<file-or-dir>,..."]
  [jobs create options]

Basic Run Scenarios

  1. Run a python script remotely:

    paperspace-python run <> [args]


    paperspace-python run a b c

  2. Run a python module remotely using the -m option:

    paperspace-python run -m <module_path> [args]


    paperspace-python run -m pip --version

  3. Run a python command remotely using the -c option:

    paperspace-python run -c "python_statement;..."


    paperspace-python run -c "import os; print(os.getcwd())"

  4. Run an executable or shell command remotely using the --command option:

    paperspace-python run --command "<executable or shell command>"


    paperspace-python run --command "ls -al"

Run Options

The <script> option is a python script or path to a python module. The script or module will be uploaded if it exists on the local file system.

Other scriptargs can be provided after the python script or module path. You can use the - option to suppress interpretation of the list of script args as paperspace-python run options.

The -m <module path> option runs the specified library module as a script. This is equivalent to the -m option of the python executable. Further paperspace run option processing is disabled after the -m option.

The -c "python_statement;..." option runs the specified python statements. This is equivalent to the -c option of the python executable. Further paperspace run option processing is disabled after the -c option.

The - option disables further run command option processing and passes the remaining arguments to the script specified. This allows you to pass arguments to your script that might otherwise conflict with run command options or jobs create options.

The --command "shell cmd" option is used to run an arbitrary executable or shell command inside the container. Note: the executable or shell command must already be available inside the container image, or be copied over using the --workspace option.

Job Options

The --workspace option allows you to specify a workspace file or directory to upload, or a git repo link to download and merge with the container. For example, to upload the current directory along with a script file run:

paperspace-python run --workspace .

See the Paperspae API jobs create documentation for more details on the --workspace option and related options.

The --ignoreFiles "<file-or-dir>,..." option can be used specify a simple comma separated list of files and directories to ignore for the workspace upload:

paperspace-python run --workspace . --ignoreFiles ",paperspace"

The following files and directories are ignored by default: .git, .gitignore, __pycache__.

Other jobs create options can be specified, such as --machineType <machine type>, --container <container image reference>, and --project <project name>.

Here are some of the other jobs create options available:

  • --project "<project name>" (defaults to 'paperspace-python')
  • --machineType [GPU+|P4000|P5000|P6000|V100] (defaults to P5000)
  • --container <docker image link or paperspace container name> (defaults to
  • --name "<job name>" (defaults to 'job for project <project name>')
  • --projectId "<existing paperspace project id>"
  • --registryUsername "<username>" (for access to a private docker registry)
  • --registryPassword "<secretpw>" (for access to a private docker registry)
  • --workspaceUsername "<username>" (for access to a private git repo)
  • --workspacePassword "<secretpw>" (for access to a private git repo)

See the Paperspae API jobs create documentation for a complete description of these options.

Dependency Options

When running python scripts on paperspace you may need to provide additional dependencies to your scripts or specify the python version. The paperspace-python run command has several options to support this: --python, --init, --pipenv, and --req. In addition you can use the --workspace option above to upload file dependencies.

The --python 2|3 option allows you specify whether to use python2 or python3 when running the script on paperspace. If ommitted, the script will be run with the same major version as is being used to run paperspace-python locally.

The --init [<>] option is used to specify a script to be run on the remote machine, inside the container, before the python script is run. If the init script name is ommitted, it is assumed to be the script named in the current directory. The script is run using source in the container bash shell. You can use this option to provide a list of commands to run to set up the dependencies for the script, such as running a list of pip install commands. However, if you are using pipenv or a requirements.txt file we recommend you use one of the options below. Multiple dependency setup options can be combinded however.

The --pipenv option is used to upload and run the Pipfile and Pipfile.lock files in the current directory, if found. These files are used on the paperspace machine to initialize the python environment using the pipenv tool, by running pipenv install within the container. Note: pipenv must already be installed in the container for this option to work. The default container used by paperspace-python already has the pipenv package installed.

The --req [<requirements.txt>] option is used specify that a requirements.txt file should be used to install the required python dependencies using pip. By default this option looks for a file named requirements.txt in the current directory, but you can override this by specifying a different file name. Note: pip must already be installed in the container for this option to work. The default container used by paperspace-python already has the pip package installed.

The --dryrun option allows you to see the resultant script that will be run on the paperspace job runner without actually running it.

All of the above options can be combined in any combination, however, the order of operations is fixed to the following:

  1. source <> is run if --init <> is specified
  2. pipenv [--two|--three] install is run if --pipenv is specified
  3. pip[2|3] install -r requirements.txt is run if --req <requirements.txt> is specified
  4. python[2|3] is run

As mentioned above, you can use the --dryrun option to see the resultant commands that will be run on the paperspace jobs cluster node for a given set of options, without actually running the commands.

Default Container

If no container option is specified when using paperspace run <> or the function the default container image used is paperspace/tensorflow-python on Docker Hub. This container has the tensorflow-gpu libraries installed for both python2 and python3, as well as several other popular packages, including numpy, scipy, scikit-learn, pandas, Pillow and matplotlib. It is based off the Google docker image with the addition of support for python3, pip3, and pipenv.

A Dockerfile for building this container image is here.

Other examples

See the scripts in the tests folder for other examples.

Other Authentication options

  1. Specify your apiKey explicitly on the function or any of the methods, e.g.:{'apiKey': '1qks1hKsU7e1k...', 'project': 'myproject',
                            'machineType': 'P5000', 'container': 'paperspace/tensorflow-python'})
  2. Set the package paperspace.config option in your python code:

    paperspace.config.PAPERSPACE_API_KEY = '1qks1hKsU7e1k...'

  3. Set the PAPERSPACE_API_KEY environment variable:

    (on linux/mac:) export PAPERSPACE_API_KEY=1qks1hKsU7e1k...

    (on windows:) set PAPERSPACE_API_KEY=1qks1hKsU7e1k...

    Note: the above methods take precedence over use of the cached api key in ~/.paperspace/config.json

  4. Set the key in the ~/.paperspace/config.json file from the command line by running:

    paperspace-python apikey 1qks1hKsU7e1k...

Using SAML, AD or GitHub credentials

Currently only email login is supported in the CLI - if you're using AD, SAML or GitHub to login to Paperspace, you will need an API key to log in with the CLI.

You can create an API key from within your Paperspace console under the API section. Login to your Paperspace console, scroll to the API section in the left navigation bar, and click CREATE AN API KEY. Follow the instructions there. You will need to pick and API token name for your API key, and also provide a description. You can copy the API key value associated with the API token name only at the time of initial creation. If you need to access your API key in the future, you can instead access it by API token name using the 'paperspace-python login' command.
