Hello! I'm trying to run this example:

import ray
import time

ray.init()
@ray.remote
def f(i):
    time.sleep(1)
    return i

futures = [f.remote(i) for i in range(4)]

print(ray.get(futures))

However I received this error:

o 2.75 GiB for objects. You can adjust these settings with ray.init(memory=<bytes>, object_store_memory=<bytes>).

Can someone help me? What am I doing wrong?

Can you make sure /home/fasr/.local/lib/python3.7/site-packages/ray-0.8.2-py3.7-linux-x86_64.egg/ray/core/src/ray/thirdparty/redis/src/redis-server has an execution permission?

Hi, I'm a bot from the Ray team :)

To help human contributors to focus on more relevant issues, I will automatically add the stale label to issues that have had no activity for more than 4 months.

If there is no further activity in the 14 days, the issue will be closed!

You can always ask for help on our discussion forum or Ray's public slack channel.
