Installation

To install requirements:

pip install -r docker/requirements.txt

Evaluating ForgER++

To download pretrained weights:

python utils/load_weights.py

To run evaluation in ObtainDiamond task:

python main.py --config configs/eval-diamond.yaml

To run evaluation in Treechop task:

python main.py --config configs/eval-treechop.yaml

Training

Downloading MineRL dataset:

python utils/load_demonstrations.py 

Training ForgER on Treechop task:

python main.py --config configs/train-treechop.yaml

Training ForgER on ObtainDiamondDense task:

python main.py --config configs/train-diamond.yaml

Caution: We didn't test reproducibility of results after moving to TF2 version and updating code for MineRL version 0.4.
