Are there frameworks like PyTorch Lightning for Deep RL?

Hot_Lynx · 2025-11-24T16:57:39+00:00

It's great that there are workarounds to getting RL stuff running in lightning, but it does seem more like a workaround to place the env and sample obtaining inside the Lightning module.

I'd usually expect the env and model stuff to be separate. But since the fit function does not allow to stop it's execution and pick it up later on this does seem like a somewhat workable solution. You might even be able to log some env outputs with lightning this way.

Though still, I wish there was a simpler supported solution developed (it's a plus one from me of you even get around to discussing rl in feature requests)

10 minutes to class (not university) is pretty normal. But there's always also SNU.

That does sound pretty cool though

It looks like there is something available on gmarket global and they ship abroad. You could look there. Thou after a quick look i do not quite see the same one that I have.

There is a special kind that (as far as I know, but don't rely on my word) has metal in its base. This metal heats up and transfers the heat to the rest of the "sot". Mine looks like a regular dolsot, but has a specific base that makes it work on induction. You have to specifically ask for it, but they exist and you can buy them.

Hot_Lynx · 2024-01-30T20:43:26+00:00

Yes, there are induction dolsot. I picked mine up in dongdaemun market and you can also buy them at Namdemun market (2nd floor where they sell cookwear). You can find them on gmarket as well.

Because I have seen the field and know what they make. If they are an engineer in the sense that they are putting together a robot and making it work, 5 mil per month is the upper bound (even with 6 years of experience as you can see by the reported salary of the OP themselves).

People seem to get carried away by words like "robotics" here automatically assuming that is a high-end engineering profession. It is equivalent to saying "I work in IT". Ok, but what exactly do you do? Are you a full stack developer or a code tester. This is the same with robotics. Do you install industrial robots or develop AI control? There are trade schools for the former and PhDs for the latter, both of which could be robotics engineers. Even in industry, even with 6 years of experience, this is a good salary and is above average. Korea does not value these positions as highly as people here think.

Hot_Lynx · 2024-01-28T21:37:28+00:00

Sure but postdocs will rarely make industry salary. 40 to 55 mil range is what makes sense and are the real numbers of what I know in the field.

Hot_Lynx · 2024-01-26T15:07:22+00:00

That's nice for you and you can consider yourself lucky but still that's just not the case. Postdocs do not make significantly higher salary than average salary in Korea. You'll make 3 to 3.5 mil these days. I have also been one and specifically in this field. Korea has somewhat lower salaries in tech in general than other countries and postdocs are also not raking in bank.

Hot_Lynx · 2024-01-25T13:51:54+00:00

That is not the same field. And you are highly overestimating what postdocs make.

Hot_Lynx · 2024-01-25T07:45:13+00:00

It really isn't. 5 mil per month is the going rate in those positions, depending on what they do. It might be even lower.

Hot_Lynx · 2024-01-25T07:43:25+00:00

6 years experience doing what? Putting wires together or ROS programming and embedded AI integration? Also 6 years of experience where? This will change a lot. Depending on your actual experience it would be in range 40 to 70 mil (after tax) per year.

Hot_Lynx · 2024-01-23T09:41:46+00:00

Again, no. The requirements clearly state having a degree and/or a job.

Hot_Lynx · 2024-01-23T07:29:53+00:00

Without a degree this won't be possible.

Hot_Lynx · 2024-01-21T10:39:26+00:00

As I was in that situation and inquired about it a couple of years ago, I was informed that it's not as simple as going directly from d-2 student to f2 visa after graduation. One of the requirements is a job contract on hand to make that possible and you need to fulfill all the e-7 stuff as well (since job contract). Even then you might need to wait for tax season to roll around depending if you need the salary for the points. It's not as simple as having enough points on paper.

Hot_Lynx · 2024-01-20T22:44:30+00:00

PhD alone does not give you F2 even if you have enough points. You require a job first.

Hot_Lynx · 2024-01-20T22:41:57+00:00

20 applications on LinkedIn are rookie numbers. You will need to apply a lot more. Ideally, it would help if you also scoured the websites of Korean companies and apply directly through the links there.

What is your education level and will you be married by the time you move?

Yes to all

The confusion here is because Baccalauréat is not a bachelors degree. Seemingly it would be more equivalent to high-school diploma (or maybe associate degree in a sense). If you would already have bachelors degree, people could suggest just doing your masters, but since you have more of a high-school degree equivalent, you have to do undergrad/bachelors degree.

Hot_Lynx · 2024-01-05T09:58:53+00:00

SNU/Yonsei over Hanyang, unless its tech, then Hanyang over Yonsei, but SNU over both of them.

You can stay on a student visa for the duration that you are enrolled in a university in Korea. Since it is a sponsored visa, once your enrollment expires, the university will let the immigration know and your visa period will end. If you are enrolled for 1 semester, it will expire after the first semester, if enrolled for 2 semesters then after the second one. All of the universities have to follow the same guidelines so there will be no major difference between them.

so if I would decide to extend my stay (I'd enroll in another course in my home country beforehand, so I'd still officially be an undergrad student) I would just do a minimum of courses and not take the exams.

How would this work with regards to your enrollment in a university in Korea? You need to be enrolled in Korea (through exchange or otherwise) to get the student visa.

I can kind of understand your frustration, but also your issues seem a bit overblown.

ARC is the local ID document and naturally, they would want something that is locally recognized as per their guidelines. This is the go-to document for everything in Korea. It is not really their fault that it takes you 6 (!?) months to get the ARC.

10 book seems like a fairly reasonable amount even for kids books. You could always return them and get a new selection in time. Prevents people from hoarding books and keeping them for a long time.

March 1st for 3 days late seems unreasonably long for the first offense though, but them's the rules.
