Collect Minecraft Video and actions

This repo is forked from https://github.com/wilson1yan/collect-minecraft.git. The code is used to collect Minecraft video and actions.

Setup

First you need to install xvfb. On Ubuntu, you can run:

sudo apt install xvfb

Then, you need to install minerl library. The latest version of minerl is 1.0.2. But this version sometimes crashes, which was also reported in https://github.com/minerllabs/minerl/issues/725.

So I recommend to use the version 0.4.4. But while installing this version, one of the dependencies cannot be accessed. So you need to follow the steps in https://github.com/minerllabs/minerl/issues/744.

You may also need to install a specific version of jdk. You can just install it in your conda environment.

Usage

sh xvfb_run.sh python collect.py -o <output_dir>

More configuration options can be found in the collect.py file. The default configuration is to collect 3000 videos of 1200 frames each. n_parallel is the number of parallel processes to run. The default is 24, and I recommend to request 32 CPU cores.

You can also configure the parameters in SimpleAgent class in collect.py.

The action dimension collected by collect.py is 4, which represents forward, backward, jump and turn.

If you set --save_pos to True, the action dimension will be 8, which represents forward, backward, jump, turn, x, y, z and yaw.
