💯 MineRL 0.2.0 released (new data, update now)!

We are excited to announce a HUGE update for minerl and the dataset UPGRADE FOR FIXED DATA!

The package is now on minerl-0.2.0, and we have released a new version of the dataset! To upgrade:

pip3 install --upgrade minerl

Then get the new dataset by running the following in python3!

import minerl
minerl.data.download('your/dataset/path`) 

Changes in minerl-0.2.0:

 # Make sure your MINERL_DATA_ROOT is set!
 export MINERL_DATA_ROOT='/your/local/path'

 # Visualizes a random trajectory 
 python3 -m minerl.viewer MineRLObtainDiamondDense-v0
  • Fixes an issue where the camera values are outside the interval [-180, 180] (#66)
  • Fixes an issue where there were invalid enum fields in the craft actions (#67)
  • Fixes an issue where the compass angle of a demonstration in the navigate task was always non-positive. (#75)
  • Fixes an issue where NavigateExtremeDense-v0 had extreme rewads (#76)
  • Adds a suppressor for the BrokenPipe error in seq_iter (#83)
  • Deprecates seq_iter for a new function sarsd_iter which returns state, action, reward, next_state, is_next_state_terminal
  • Fixes an issue where trajectories would complete the challenge but additional frames would be in the data (#127)
  • Removes a corrupted data stream (tempting_capers_shapeshifter-14_…) (#130)
  • Fixes an issue with the data downloader where the read operation would time out (#131)
  • Adds resuming of downloads to the data downloader!
  • Fixes massive issue with data alignment!
  • Frames at the beginning of experiments with teleportation are (mostly) removed!
  • Fixes an issue where random rewards would appear during experiments (opening a furnace).
  • Adjusts the brightness levels of the simulator and dataset to gamma=2.
  • Adds ambient occlusion to the dataset and the simulator to slightly improve graphical quality!
  • Fixes an issue where items would sometimes disappear from the inventory of player trajectories while they crafted.
  • Adds a versioning system to the dataset, requiring that you use the latest version associated with your MineRL package.

SUBMISSIONS SHOULD BE OPEN NEXT WEEK SO GET EXCITED! 💯💯💯

ChainerRL Baselines for Auxiliary Environments released!

The awesome folks over at PFN have released some initial baselines in their framework ChainerRL on some of the auxiliary envrionments (Treechop + Navigate)!

Check out their amazing work here!

They’ve released DDDQN, Rainbow, & PPO, and they solved MineRLTreechop! Feel free to ask them if you have any questions!

Note: when AIcrowd releases the competition submission and evaluation kit these baselines will be converted into that format an appear on the leaderboard. So check back for updates.
