Flatland Challenge

Evaluation server hardware specifications

About 1 year ago

Is GPU available on evaluation server?
I think GPU is necessary if we want to experiment with global observation.

NeurIPS 2019 : MineRL Competition

The evaluation result does not match my local testing

About 1 year ago

My code is also running on TF 1.13.1.
But TF version 1.13.1 is specified on my environment.yml file.
I’m still confused about what went wrong.

The evaluation result does not match my local testing

I have a same problem.
Evaluation successful but only 1 episode with 4 steps.

Sample efficiency and human dataset

Over 1 year ago

Let me ask another question about MINERL_TRAINING_MAX_INSTANCES = 5 in competition_submission_starter_template. I’m not quite sure how INSTANCE is defined.
Does it mean that max 5 gym env could be run in parallel while training?
Or max 5 parallel trainer perform update function independently and somehow merge gradients periodically?
Or max 5 processes (regardless of doing what kind of job) can be deployed while training?

Evaluation successful but actually it is not

Could you look into this issue?

Is submission system stuck?

Over 1 year ago

Hello. I’m Sungbin Choi. I’m participating at Unity Obstacle Tower Challenge.
Usually before, it took less than an hour to get evaluation results,
but today now it’s been more than 3 hours and I still cannot get evaluation results back.
I need to see evaluation results to choose and submit best one at last.
Since today is last day of the challenge, I’m worried I cannot choose one.

How can I get my evaluation error log?

Over 1 year ago

Oh, now I found the problem. It was about file permission issue.
Thanks~

How can I get my evaluation error log?

Over 1 year ago

Hello. I’m SungbinChoi participating at Unity Obstacle Tower Challenge.
I tried to submit a few runs today but evaluation error occurred every time.
I want to see error logs ASAP to fix the problem.
https://gitlab.aicrowd.com/sungbinchoi/obstacle-tower-challenge

I’m also wondering what should I do if I encounter evaluation error again.
Do I need to send direct message to request error log again or is there any other way around?

I think it’s stuck again.

Possible bug with tower-seed in env 2.0

Over 1 year ago

Yes, I guess the bug is not fixed yet.
I’ll post a comment on that github issue link.
->
Now I got the answer.
They said tower-seed value range is intentionally limited to 100 in Round 2.

Possible bug with tower-seed in env 2.0

Over 1 year ago

Although I defined specific tower-seed when I reset the environment,
random seed is assigned instead
when tower-seed >= 100.
It looks like env 2.1 has the same problem.
