Python package providing easy to use gym environments and a simple data api for the MineRLv0 dataset. 

**To [get started please read the docs here](http://minerl.io/docs/)!**

![](http://www.minerl.io/docs/_images/demo.gif)
## Installation

With JDK-8 installed run this command
```
pip3 install --upgrade minerl
```

## Basic Usage

Running an environment:
```python
import minerl
import gym
env = gym.make('MineRLNavigateDense-v0')


obs = env.reset()

done = False
while not done:
    action = env.action_space.sample() 
 
    # One can also take a no_op action with
    # action =env.action_space.noop()
    
 
    obs, reward, done, info = env.step(
        action)

```

Sampling the dataset:

```python
import minerl

# YOU ONLY NEED TO DO THIS ONCE!
minerl.data.download('/your/local/path')

data = minerl.data.make(
    'MineRLObtainDiamond-v0',
    data_dir='/your/local/path')

# Iterate through a single epoch gathering sequences of at most 32 steps
for current_state, action, reward, next_state, done \
    in data.batch_iter(
        num_epochs=1, seq_len=32):

        # Print the POV @ the first step of the sequence
        print(current_state['pov'][0])

        # Print the final reward pf the sequence!
        print(reward[-1])

        # Check if final (next_state) is terminal.
        print(done[-1])

        # ... do something with the data.
        print("At the end of trajectories the length"
              "can be < max_sequence_len", len(reward))
```


Visualizing the dataset:

![viewer|540x272](http://www.minerl.io/docs/_images/cropped_viewer.gif)
```bash

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

# Visualizes a random trajectory of MineRLObtainDiamondDense-v0
python3 -m minerl.viewer MineRLObtainDiamondDense-v0

```
