Stateful Distributed Computing in Python with Ray Actors

[@cansucandan4124]

Thanks! I can't wait for you to share more videos about Ray for more practice.

[@TheDevildragon95]

Good introduction to the topic, now I will be able to migrate my application to a distributed system.

[@dantedt3931]

This is good. Would like to see more videos on Ray.

[@jamesmckeown2746]

Thanks for the clear explanations! I'd be interested to see an example of recovery in a multi node cluster where a node fails and its actors are recovered on another node.

[@AkshatDobhal-m3h]

its a crime to not release an entire playlist and just 5 videos for ray.

[@timharris72]

This was a really good explanation. Thanks for posting this!

[@feifeizhang7757]

Very informative video. Short and clear!

[@ramirotapia2217]

Amazing i was searching for this explanation. is there a way to make only a method inside a class remote? maybe thinking to override the remote method accordingly

[@jonathanuniversity]

hmmmm, I actually haven't tried that ever. You can try using a regular (un-decorated) Python class but then use the @ray.remote decorator just on a single method of the class. The thing to keep in mind though is what variables/state from the main class the remote method might access.

[@mojtabatorabi3724]

thanks for the content. I have a question how can I set a timeout for executing a task for a given Actor ?

[@skysavani7095]

Thanks for the clear explanations! can you please make a video for how to debug code with ray

[@jnevercast]

are there any guarantees when you call ray.get() to get age, that all of the grow_older invocations have resolved? I presume yes for each actor (keeping in-line with each actor is syncronous)

[@jonathanuniversity]

yeah that is the case for a specific actor but not guaranteed between actors necessarily. To synchronize between actors you usually pass object references between them using remote() function calls.

[@ybbyang]

how to get people[0]'s value like age or name on host. using pepple[0].age report errors.

[@jonathanuniversity]

I don't believe you can directly access an Actor's attributes (unless things have changed in a recent version of Ray) unfortunately. To access people[0] age you would need to define a getter method on the class and call it like people[0].get_age.remote()

[@Nick-tv5pu]

Just found out Ray doesn't ship types? At least not for anything except (sometimes) tasks? Wtf? I thought this was supposed to be a modern and developer-friendly library?
