💯 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'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.


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.
