Issue not created when tag is pushed with changes

Almost 4 years ago

Oh I missed that part. This solved my issue. Thanks!

Issue not created when tag is pushed with changes

Almost 4 years ago

I edited run.py and pushed using

git push aicrowd master
git push aicrowd TAGNAME

But I do not see any issue being created in my repo, and it is also not shown in the list of recent submissions. What might be the issue?

🚉 Questions about the Flatland Environment

Almost 4 years ago

Hello!

I noticed that there the environment has a remove_agents_at_target parameter that defaults to True . Can we assume that this will always be True during evaluation?

How to use TreeObsForRailEnv in remote client?

Almost 4 years ago

When I initialize a TreeObsForRailEnv and pass it as the obs_builder_obj for the remote client, I get the following error:

# Relevant code chunk
tree_observation = TreeObsForRailEnv(max_depth=2)
observation, info = remote_client.env_create(obs_builder_object=tree_observation)
# Error
Traceback (most recent call last):

NeurIPS 2019 : MineRL Competition

Agent Behavior for conflicting actions?

Over 4 years ago

In the ObtainDiamond action space, there seems to be some action pairs that “conflict” (one cannot occur with another):

  1. Forward / Back, Left / Right
  2. nearbyCraft / nearbySmelt
  3. Attack / place

What happens when both are used in single action? (as in, what happens if an action a has both “Attack” and “Place” true?)

Can the agent get reward repeatedly?

Over 4 years ago

@shadowyzy you can find the information about environments here:

MineRLObtainDiamond-v0

During an episode the agent is rewarded only once per item the first time it obtains that item in the requisite item hierarchy for obtaining an iron pickaxe.

MineRLObtainDiamondDense-v0

During an episode the agent is rewarded every time it obtains an item in the requisite item hierarchy to obtaining a diamond.


If this is true, it might be that ObtainDiamond and ObtainDiamondDense is reversed? Not sure what’s going on exactly :thinking:

AIcrowd Submission Failed: 404 Tree Not Found (submission_hash: None)

Almost 5 years ago

Hello!

Indeed, the issue was resolved after submitting again. It seems like an one-off issue that can be closed safely.

FYI though,

  1. The repository was created in GitLab website.
  2. push master than push tag was used

Thanks for the great work!

It seems to me that the queue is stuck. Would you happen to know the reason why?

Hello :slight_smile:

I was trying to submit using the default provided template: https://github.com/minerllabs/competition_submission_starter_template

I just added my name to authors in aicrowd.json and pushed the tag, but this error came out.
Has anyone seen similar issue?

Thanks!

(Windows) Running MineRL Recording Mod Installer gives "Java Runtime Environment not found" error

It is indeed working now! Thank you for the help.

(Windows) Running MineRL Recording Mod Installer gives "Java Runtime Environment not found" error

About 5 years ago

I put the minerl.jar file in C:\Users\\[username]\AppData\Roaming\\.minecraft\mods.

When I try to connect to the MineRL server, it is stuck in Logging in… screen.


I attach a list of my mods:

I have a Ubuntu computer with the exact same versions, and that works well, so I don’t think it’s a version problem.

(Windows) Running MineRL Recording Mod Installer gives "Java Runtime Environment not found" error

About 5 years ago

I tried manually installing Mincraft Forge and downloading the mod (minerl.jar). This also doesn’t work, as double-clicking the jarfile does nothing.

When I run it on terminal, I get the following output:

$ java -jar .\minerl.jar
no main manifest attribute, in .\minerl.jar

NOTE: This is a question about MineRL Dataset, not about the competiton.

I have installed Minecraft and downloaded the MineRL Recording Mod installer from this page. However, when I run the downloaded installer-signed.exe, I get the error message below:

This is on Windows 10, and I have JRE installed:

How to "nudge" the admins

Hello! How am I suppose to “nudge” the admins on GitLab?

I also got the same error message: it seems like a temporary issue on the server side. I sent an email earlier today and @mohanty replied that he is working on it.

Problem with 1.1_windows

Ubuntu user here. I thought the blank small screen was intentional? I also get the same screen when I use the Obstacle Tower environment.

Simple action interpreter widget

I created a simple action interpreter widget for the Obstacle Tower Environment! You can change the numbers in the black input box to get an appropriate interpretation of each action.

Evaluation Error: Unable to orchestrate evaluation. Core services failed to start

That was weird? I changed nothing and just pushed a new tag and submitted, and it worked! :confused:

Thank you for your help @mohanty and @arthurj!
