Editor.py missing package jpy_canvas

Hello @pf1, @hagrid67 is the authority on this matter!

Metadata.csv is missing from the latest testset

7 months ago

Hello Sahil, which archive are you referring to? I see the metadata.csv in both test-neurips2020-round2-v0.tar.gz and test-neurips2020-round1-v1.tar.gz from the Resources page.

edit: This was an error in the doc that we’ve now corrected, thanks for the report!

Hey @jakob_stigenberg, yes the event was recorded, we will release the video publicly soon!

🏆 NeurIPS 2020 Flatland Winners

8 months ago

Round 2 has finished, concluding the NeurIPS 2020 edition!

We have received over 2’000 submissions from over 700 participants coming from over 51 countries! We have been thrilled by your contributions and enthusiasm.

And the winners are… :drum:

RL Track

  • :1st_place_medal:JBR_HSE, 214.15 points
  • :2nd_place_medal:ai-team-flatland, 181.497 points
  • :3rd_place_medal:SSG-RL, 143.985 points

Non-RL Track

  • :1st_place_medal:An_Old_Driver, 297.507 points
  • :2nd_place_medal:MasterFlatland, 296.347 points
  • :3rd_place_medal:vetrov_andrew, 273.339 points

Congratulations to all of them! The race was intense :tada: :clap:

Community Prizes

In parallel to the competition, participants also competed for Community Prizes, contributing to the Flatland ecosystem by building tools and implementing ideas that will help other participants.

And the winners are:

The submissions were few, but they were very impressive and inspiring. We warmly congratulate all four winners.

What’s next?

This competition may be finished, but Flatland is just getting started!

We are happy to announce that not only will we apply for a new competition at NeurIPS next year, but we are also organizing another challenge before that in the context of the AMLD 2021 conference, which will take place in Lausanne, Switzerland. :switzerland::steam_locomotive::mountain:

Beyond competitions, Flatland will also become a long-term benchmark, accepting submissions on a permanent basis. Our goal is to measure the progress around the real-world problem of train scheduling, and progress doesn’t happen only twice a year!

For this purpose, a new “post-challenge” round will be open soon and will stay open until next competition to allow the community to keep searching.

Thank you all again for your participation, and see you soon on the next leaderboard!

The official results will be announced at NeurIPS

8 months ago

Hello everyone,

The review process has been long and complex!

We will ultimately present the official results during the NeurIPS conference, as part of the competition track.

🚇 5 days left! Final tips & tricks for the home stretch

8 months ago

Hey @harshadkhadilkar, the review process took more time than expected, as it was challenging to establish if each solution was using RL in a meaningful way.

We will announce the official results at NeurIPS.

Will the leaderboard remain open?

9 months ago

Hello @guillaume_alleon,

Yes we plan to keep the submissions open! For now new submissions will appear under “post-challenge submissions” (go to “Leaderboard filters” -> “Include post-challenge submissions” to show them).

We will also announce the launch of the new Flatland event at NeurIPS :smiley:

This challenge has raised a lot of interest from both participants and partners, the adventure is just getting started! :rocket:

Cheers,
Florian

Submission error: weird error during conda clean

9 months ago

This is probably related to this: Build problem with the current `environment.yml` file

Make sure your requirements.yml only contains what’s strictly necessary!

It’s (a): you can submit until the deadline!

Different CUDA version

9 months ago

But, as the evaluation environment doesn’t include a GPU, do you really need to setup CUDA in your submissions?

Flatland-Visualization: Visual Analytics of Flatland Episodes

9 months ago

Wow, amazing work :star_struck: :clap:

It’s not clear to me how to create new regions: it seems that I need to select multiple cells by keeping my mouse pressed on the Map View? I don’t see the gray overlay on the Map View or the edges between the vertices on the Graph View

Evaluation took too long

9 months ago

Hello,

How do I deal with the fact that my 8h of evaluation time ran out and the percentage complete is still > 0.25

This is fine, this means your submission stopped because it reached the overall time limit instead of the “percentage done” limit. Most OR submissions reach the overall timeout (you can see on the leaderboard that their mean “% Done” is very high).

An early submit on the remote client results in an error and doing nothing also results in an error : Timeout : Evaluation took too long.

I don’t understand what you mean?
