Getting Started with Ray
|
||
------------------------
|
||
|
||
Check out :ref:`gentle-intro` to learn more about Ray and its ecosystem of libraries that enable things like distributed hyperparameter tuning,
|
||
reinforcement learning, and distributed training.
|
||
|
||
Ray uses Tasks (functions) and Actors (Classes) to allow you to parallelize your Python code:
|
||
|
||
.. code-block:: python
|
||
|
||
# First, run `pip install ray`.
|
||
|
||
import ray
|
||
ray.init()
|
||
|
||
@ray.remote
|
||
def f(x):
|
||
return x * x
|
||
|
||
futures = [f.remote(i) for i in range(4)]
|
||
print(ray.get(futures)) # [0, 1, 4, 9]
|
||
|
||
@ray.remote
|
||
class Counter(object):
|
||
def __init__(self):
|
||
self.n = 0
|
||
|
||
def increment(self):
|
||
self.n += 1
|
||
|
||
def read(self):
|
||
return self.n
|
||
|
||
counters = [Counter.remote() for i in range(4)]
|
||
[c.increment.remote() for c in counters]
|
||
futures = [c.read.remote() for c in counters]
|
||
print(ray.get(futures)) # [1, 1, 1, 1]
|
||
|
||
|
||
You can also get started by visiting our `Tutorials <https://github.com/ray-project/tutorial>`_. For the latest wheels (nightlies), see the `installation page <installation.html>`__.
