# cnvrg SDK V2

# Getting Started

The cnvrg SDK was developed in Python and is designed to help data scientists to interact with cnvrg from their code, experiments and models. Through the SDK, you can create experiments, manage models, automate your machine learning pipeline and more.

The topics in this page:

# Prerequisites

In order to run the pip commands, Python (version 3.6 or later) should be installed on the system.

# Download and Install the cnvrg SDK

    # Install options

    When on self-hosted cnvrg environemnt, you can specify an option for cnvrgv2, to fit the object storage you intend to work with in your cnvrg environment.

    For Metacloud, we'll use the default installation without any option.

    Add the options to the install command as needed, you can add multiple options by separating with comma:

    pip install "cnvrgv2[options]"

    available options are:

    • azure - Install packages relevant for Azure storage client
    • google - Install packages relevant for GCP storage client
    • python3.6 - Install specific dependencies for python version 3.6

    # SDK Operations

    # Authenticating the cnvrg SDK

    You can can authenticate when credentials as parameters:

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg(domain="https://app.cnvrg.io",
              email="Johndoe@acme.com",
              password="123123",
              )

    Login command parameters

    Parameter Value Type Description required default
    domain Text cnvrg domain/url starting from http/s, excluding the organization slug e.g. https://app.cnvrgdomain.com/ Yes
    email Text User email Yes
    password Text authenticate using password Password or token are required
    token Text authenticate using the API Token Password or token are required
    organization Text cnvrg organization, this can be used when the user is a member of multiple organizations No First organization the user was added to

    For Metacloud and self-hosted cnvrg environments with SSO authentication, The user's API Token must be used instead of the Password, with the token parameter. the token can be retrieved from the user settings page, under API Token field: API Token

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg(domain="https://app.domain.metacloud.cnvrg.io",
              email="Johndoe@acme.com",
              token="YOUR API KEY")

    NOTE

    As a security measure, please do not put your credentials into your code.

    # Inside a cnvrg job scope

    The cnvrg SDK will already be initialized and authenticated with cnvrgv2 using the account that is logged in. You can start using cnvrg SDK functions immediately by running:

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()

    # Authenticate using a local configuration file

    You can authenticate to the cnvrg SDK by creating a configuration file in your working directory

    • In your working directory create a directory called .cnvrg
      mkdir .cnvrg
    • Inside the directory .cnvrg create a configuration file named cnvrg.config
    • Edit the file and insert the following:
      check_certificate: <false/true>
domain: <cnvrg_full_domain>
keep_duration_days: null
organization: <organiztion_name>
token: <user_access_token>
user: <user_email>
version: null
    • Once you finish editing, save the file Now you can simply run the following in your code and it will log you in automatically:
    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()

    # Authenticate using environment variables

    You can authenticate to the cnvrg SDK by setting the following environment variable:

    • CNVRG_JWT_TOKEN: Your API token ( You can find it in your user settings page)
    • CNVRG_URL: Your cnvrg url that you use to view cnvrg through the browser, for example: https://app.prod.cnvrg.io
    • CNVRG_USER: Your email that you use to log in to cnvrg
    • CNVRG_ORGANIZATION: The organization name you use Once you set those environment variables, you can simply run the following and it will log you in automatically:
    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()

    NOTE

    The following documentation assume you have successfully logged in to the SDK and loaded the cnvrg object

    # User Operations

    # Verify you are logged in

    To get the logged in user object you can simply run:

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()
user = cnvrg.me()

    Once you have the user object you can get the user fields like: email, username, organizations, git_access_token, name, time_zone and more.

    For example:

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()
user = cnvrg.me()
email = user.email

    # Set the default organization

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()
cnvrg.set_organization("my-org")

    NOTE

    As a default, your current organization will be used

    # Project Operations

    # Create a new project

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()

    # Get the project's object:

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()
myproj = cnvrg.projects.get("myproject")

    Once you have the project object you can get the project fields like: title, slug, git_url, git_branch, last_commit, num_files and more.

    For example:

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()
myproj = cnvrg.projects.get("myproject")
title = myproj.title

    ws.tensorboard_url

    Stop the Tensorboard session:

    ws.stop_tensorboard()

    # Experiment Operations

    # Experiment slug

    In many commands, you will need to use an experiment slug. The experiment slug can be found in the URL for the experiment.

    For example, if you have an experiment that lives at: https://app.cnvrg.io/my_org/projects/my_project/experiments/kxdjsuvfdcpqkjma5ppq, the experiment slug is kxdjsuvfdcpqkjma5ppq.

    # Fetch the experiment object

    Once you have the experiment's slug you can fetch it with the 'get' command:

    from cnvrgv2 import Cnvrg
cnvrg = Cnvrg()
myproj = cnvrg.projects.get("myproject")

      # Charts

      You can create various charts by using the sdk, for example create a linechart showing the experiments loss:

      from cnvrgv2 import Cnvrg, LineChart
cnvrg = Cnvrg()
myproj = cnvrg.projects.get("myproject")
e = myproj.experiments.get("exp-slug")

loss_vals = []
# experiment loop:
for epoch in range(8):
    loss_vals.append(loss_func())

# attach the chart to the experiment
loss_chart = LineChart('loss')
loss_chart.add_series(loss_vals, 's1')
e.log_metric(loss_chart)

      You will immediately see the chart on the experiment's page:

      WARNING

      chart_name can't include "/"

      # Update existing chart:

      Use following command to update existing chart with added values:

      e.update_chart(key="loss",data=[1,2,3,4],series_name='s1')

      You can create all different types of charts:

      # Heatmap:

      In case of Heatmap, list of tuples that form a matrix. e.g, 2x2 matrix: [(0.5,1),(1,1)]

      from cnvrgv2 import Heatmap
heatmap_chart = Heatmap('heatmap_example2',
                        x_ticks=['x', 'y'], y_ticks=['a', 'b'], min=0,max=10)
heatmap_chart.add_series([(0.5,1),(1,1)], "s1")
e.log_metric(heatmap_chart)

      Example heat map

      Typing information: x_ticks and y_ticks must be a List and matrix is a list of tuples in struct (x,y,z). color_stops is optional and is a List of Lists with size 2, where the nested first value is a float 0 <= X <= 1, and the second value is the hex value for the color to represent matrix values at that point of the scale. min and max are optional and should be numbers corresponding to the minimum and a maximum values for the key (scaling will be done automatically when these values are not submitted).

      Each struct corresponds to a row in the matrix and to a label from the y_ticks list. The matrix is built from the bottom up, with the first struct and y_tick at the bottom edge. Each value inside the struct corresponds to each x_tick. Using steps and groups allow you to submit the same heatmap across different steps and visualize it in a single chart with a slider to easily switch between the charts. steps should be an integer and group should be a string.

      Steps and groups:

      Using steps and groups allow you to submit heatmaps across different steps and visualize it in a single chart with a slider to easily move between the steps. steps should be an integer and group. Multiple steps should be grouped with a single group.

      Animated Heatmap

      # Bar chart:

      • Single bar:

        from cnvrgv2 import BarChart
bar_chart = BarChart('bar_example', x_ticks=['bar1', 'bar2'])
bar_chart.add_series([1, 2],'s1')
e.log_metric(bar_chart)

      • Multiple bars:

        from cnvrgv2 import BarChart
bar_chart = BarChart('bar_example1', x_ticks=['bar1', 'bar2'])
bar_chart.add_series([1, 2, 3],'s2')
bar_chart.add_series([3, 4],'s3')
e.log_metric(bar_chart)

      Example bar chart

      The x_ticks list will populate the labels for the bars, and the corresponding series values will dictate the value of the bar for that category. min and max are optional and are numbers that correspond the lower and upper bounds for the y values. Optionally, you can set each bar to be a specific color using the colors list of hex values, with each hex value corresponding to each x value.

      Steps and groups:

      Using steps and groups allow you to submit bar charts across different steps and visualize it in a single chart with a slider to easily move between the steps. steps should be an integer and group. Multiple steps should be grouped with a single group.
