Installation

You can simply install Mars via pip:

pip install pymars

Create a default session

Mars needs to create a session to run tasks. You can use mars.new_session() to create a local session:

import mars
mars.new_session()

Then calling execute() on a Mars objects e.g. tensor, computation will be performed.

a = mt.random.rand(10, 10)
a.dot(a.T).execute()

If no default session is created, Mars will create a session for you when executing a task. You will see messages when the task is being created.

When you finish working with the local session, you can stop it using mars.stop_server():

mars.stop_server()
