Client code consists of two parts: the Meeshkan agent controlled with command-line interface and the Python library meeshkan.

Using the client requires signing up at If you want to control your jobs via Slack, you also need to set up the Slack integration as explained in the documentation.

How it works

The Meeshkan agent

The agent is a daemonized process running in the background. Agent is responsible for scheduling jobs (Python scripts) and interacting with them. Agent is responsible for, e.g.,

  1. sending job notifications so that you know how your jobs are doing and
  2. listening to instructions from the server. If you remotely execute the command to, for example, stop a job, the agent gets the instruction to stop the job from the server and stops the job.

The agent is managed using the command-line interface (CLI).

The Meeshkan Python library

The Python library imported with import meeshkan is used in scripts to control the notifications you get. For example, by including a command such as

import meeshkan
meeshkan.report_scalar("Train loss", loss)

in your Python script you specify that notifications you get should contain the value for loss. Similarly, meeshkan.add_condition can be used to send notifications for arbitrary events. For detailed documentation of the library usage, see below.

Note that using meeshkan in your Python scripts is optional (though recommended). If you do not specify reported scalars, you will only get notifications for when jobs start or finish.

Quick start

Please see the instructions in

Command-line interface

To list available commands, execute meeshkan or meeshkan help:

Usage: meeshkan [OPTIONS] COMMAND [ARGS]...

  -h, --help  Show this message and exit.
  --version   Show the version and exit.

  clean          Alias for `meeshkan clear`
  clear          Clears Meeshkan log and job directories in ~/.meeshkan.
  help           Show this message and exit.
  list           Lists the job queue and status for each job.
  logs           Retrieves the logs for a given job.
  notifications  Retrieves notification history for a given job.
  report         Returns latest scalar from given job identifier
  setup          Configures the Meeshkan client.
  sorry          Send error logs to Meeshkan HQ.
  start          Starts Meeshkan service daemon.
  status         Checks and returns the service daemon status.
  stop           Stops the service daemon.
  submit         Submits a new job to the service daemon.

In all instances used, a JOB_IDENTIFIER can be either the job's UUID, the job number, or a pattern to match against the job's name. In the latter case, the first match is returned.

Start the agent


meeshkan start

starts the agent as daemonized service. If you get Unauthorized error, please check your credentials. Also check known issues. If the problem persists, please contact Meeshkan support.

Submit a script for execution

Submit a Python script as job:

meeshkan submit [--name job_name] [--report-interval 60] examples/

The agent runs submitted jobs sequentially in first-in-first-out order. By default, the submit command will run your code without time-based notifications (see below). When presented with the -r/--report-interval flag, the service will notify you with recent updates every time the report interval has elapsed. The report interval is measured in seconds. The default argument (if none are provided) is 3600 seconds (i.e. hourly notifications).

List submitted jobs

meeshkan list

Retrieve stdout and stderr for a job

meeshkan logs JOB_IDENTIFIER

Here JOB_IDENTIFIER can be either the job's UUID, the job number, or a pattern to match against the job's name.

You will get a complete output of stderr and stdout for the given job, and it's output path for any additional files.

Review job notification history

meeshkan notifications JOB_IDENTIFIER

Review latest scalar reports

meeshkan report JOB_IDENTIFER

Canceling a job

meeshkan cancel JOB_IDENTIFIER

If the job is currently running, you will be prompted to verify you want to abruptly cancel a running job.

Stop service

meeshkan stop

Remote Control with Slack


A core functionality of the Meeshkan agent is it's seamless integration with common platforms. For our first integration, we chose to focus on Slack.

Setup and Security

When signing up to the first, you may integrate your agent to a specific workspace and channel (the channel may also be a specific user!). From that moment on, you are considered the de-facto admin for that integration, and by default, you are the only user with remote access to the agent. We take security very seriously, and would never expose your machine, code or data to any 3rd party API.

Every Slack channel may have several integrations. When issuing a remote controlled command (as opposed to responding to one), the command is assigned to the agent you integrated. If no such agent exists, it is assigned to the agent for which you are authorized to run remote commands. If more than one such agent exists - well, that shouldn't happen.

Slash Commands

Remote controlling from Slack means using /slash commands. All Meeshkan-related commands are prefixed with /mk-*. As we continue development, we will roll out more and more interactive commands. Eventually, we intend on making things even easier with simple NLP mechanisms.

Controlling Authorized User List

To grant users other than yourself remote access to your agent, you can use the /mk-auth command where you integrated the agent. The /mk-auth command has 3 subcommands:

  1. /mk-auth list (also /mk-auth ls): lists the users allowed to run commands remotely.
  2. /mk-auth add @user1 [@user2 ...] (also /mk-auth allow and /mk-auth permit): adds user(s) to the authorized list
  3. /mk-auth rm @user1 [@user2 ...] (also /mk-auth del, /mk-auth delete, /mk-auth remove): removes matching users from the list.

Running code from GitHub

You may issue a remote command to run code from GitHub (if you are authorized to do so) using: /mk-gitrun repo[@commit/branch] entrypoint [job name] [report interval]. Where you may choose a specific commit/branch to use, but you have to specify a repository and entry point (the file to run). Job name can be extended to multiple words using qutoation marks. Examples include:

/mk-gitrun Meeshkan/meeshkan-client examples/
/mk-gitrun Meeshkan/meeshkan-client@release-v-0.1.4 examples/ "some long job name"
/mk-gitrun Meeshkan/meeshkan-client examples/ 10

To run code from private repositories, you would need to input a GitHub Access Token with running meeshkan setup (see the documentation for more information).

Stopping a command

Finally, sometimes you may want to issue a remote command to stop a scheduled or running job. This is done with a simple /mk-stop job_identifier, where job_identifier corresponds to the same usage as the CLI (it may be a job name, number, UUID, pattern, etc...)

Usage as Python library

For detailed API reference, see


The purpose of the Python API is to be as intuitive, minimal and least invasive as possible. Once the agent has been started using meeshkan start, you can communicate with it from your Python scripts through meeshkan library.

To begin, import meeshkan.

Starting, stopping and restarting the agent

As alternatives for the CLI interface, you may use meeshkan.init(token=...) to start the agent with a new token.
If the agent is already set up via the CLI (meeshkan setup), you may simply call meeshkan.init() or meeshkan.start().
You may further restart the agent with meeshkan.restart() and stop the agent completely with meeshkan.stop()

Reporting scalars

You can report scalars from within a given script using meeshkan.report_scalar(name1, value1, name2, value2, ...). The command allows reporting multiple values at once, and giving them self-documenting names (you may use anything, as long as it's a string!).

Some examples include (assume the mentioned variables exist, and are updated in some loop, e.g. a training/evaluation loop):

meeshkan.report_scalar("train loss", train_loss)  # Adds a single value for this process
# Or add multiple scalars simulatenously
meeshkan.report_scalar("train loss", train_loss, "evaluation loss", eval_loss, "evaluation accuracy", eval_acc)
# Or possibly combine them for a new metric
meeshkan.report_scalar("F1", 2*precision*recall/(precision+recall))

Adding conditions

The agent only notifies you on either a scheduled notification (using the --report-interval/-r flag, e.g. hourly notifications), or when a certain criteria has been met. You can define these criteria anywhere in your code (but outside of loops, these conditions only need to be set once!), even before your scalars have been registered. When a scalar is used before it is registered, a default value of 1 is used in its place.

Consider the following examples:

# Notify when evaluation loss and train loss are significantly different.
meeshkan.add_condition("train loss", "evaluation loss", lambda train_loss, eval_loss: abs(train_loss - eval_loss) > 0.2)
# Notify when the F1 score is suspiciously low
meeshkan.add_condition("F1", lambda f1: f1 < 0.1)

Submitting notebooks and/or functions

When working with Jupyter notebooks, one may want to test the entire notebook as a long running task, or test individual long running functions. With Meeshkan, you can easily achieve both of these!
From a notebook instance, you may submit the entire notebook with:

meeshkan.submit_notebook()  # Default job name, report interval, for a password-free notebook
# If your notebook server is password protected, you may need to supply the password:
# Finally, you can customize the job's name and report interval as well! The full argument list is:
meeshkan.submit_notebook(job_name=..., report_interval=..., notebook_password=...)

Sometimes, we only need to test out an individual function, or perhaps you would like to skip the time it took to download, parse and process a dataset. Meeshkan also offers a solution for that via meeshkan.submit_function. Consider:

def train(optional_args=DEFAULT_VALUES):
    # some training process with global dataset, model, optimizer, etc...

meeshkan.submit_function(train, args=[50])  # Sends 50 to optional_args
meeshkan.submit_function(train, args=[[50]])  # Sends [50] to optional_args
meeshkan.submit_function(train, kwargs={'optional_args': [50]})  # Sends [50] to optional_args via kwargs

Working with Amazon SageMaker

For an example of how to use Meeshkan to monitor Amazon SageMaker jobs, see the example notebook.

Known issues

Start occasionally fails in macOS

In macOS, running meeshkan start may fail with

objc[60320]: +[NSValue initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.

This happens because of threading restrictions introduced in macOS High Sierra. You can read more about it here, here, here, and here. We hope to find a permanent fix for this, but in the meanwhile you can run


before starting the client and then try again. If this does not fix the issue, please contact
