problem with gym while installing minerl

[1Sep7]

so i decided to try minerl and before even starting i found this problem while doing "pip install minerl"

Preparing metadata (setup.py) ... error
error: subprocess-exited-with-error

note: This error originates from a subprocess, and is likely not a problem with pip.

Hey. Installing from pip does not work with newer Python versions sadly. You need to install MineRL from the github with the settings in the README: https://github.com/minerllabs/minerl

Which version of Python do we need? I don't see where in the README the instructions for the correct python version are.

[Miffyli]

Yes, those were never added as "the current Python version was the right at the time" 😅 . You can try using e.g., Python 3.8, but I think this leads to issues with other dependencies not supporting older Pythons. This is a dependency-mess that makes installation of the older MineRLs difficult, and maintainers have not had time to fix these issues

[lukedoma1]

Okay, thank you. Yeah, I wasn't able to figure out how to install v0.3.7, but I eventually got v1.0.0 to work with python 3.10 using Ubuntu VM.

If you find an install combination that works, also please feel free to open up a PR documenting it to help others get set up!

I managed to get MineRL 0.4.4 working on Ubuntu 18.04.6 with Python 3.11. Here’s the step-by-step installation guide that worked for me. I've also shared this setup in my GitHub repository.

Take a look at this guide if you have issues with MixinGradle while installing MineRL 0.4.4.

Take a look at this table to check the latest GCC your OS supports.

# Step 1: Create a Conda environment with Python 3.11
conda create -n exp_minerl044 python=3.11
conda activate exp_minerl044

# Step 2: Install dependencies (Gym 0.19.0)
conda install conda-forge::openjdk=8 
pip install setuptools==65.5.0 pip==21 wheel==0.38.0
pip install gym==0.19.0
pip install --upgrade pip

# Step 3: Update GCC (if required). You need gcc >= 9.1.
# Take a look at this table https://askubuntu.com/a/1163021/901082 to check the latest GCC your OS supports
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install -y software-properties-common
sudo apt-get install gcc-10 g++-10
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 120
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-10 120

# Step 4. Install Dev Dependencies
sudo apt install -y libxml2-dev libxslt1-dev gfortran libopenblas-dev

# Step 4: Download and install MineRL 0.4.4
OPENSSL_ROOT_DIR=$CONDA_PREFIX pip download --no-binary :all: minerl==0.4.4
tar -xvf minerl-0.4.4.tar.gz
cd minerl-0.4.4

# Step 5: Fix compatibility issues in requirements and build.gradle
# - Remove the gym line from requirements.txt
# - Edit minerl-0.4.4/minerl/Malmo/Minecraft/build.gradle:L19 as per this guide:
#   https://github.com/MineDojo/MineDojo/issues/113#issuecomment-1908997704
#   Add the following Maven repository:
#   maven { url 'file:/absolute-path/to/that/repo's/parent' }

pip install -r requirements.txt
pip install .

# Step 6: Install additional tools for your experiments
pip install wandb tensorboard moviepy stable-baselines3
pip install --upgrade git+https://github.com/DLR-RM/stable-baselines3.git # Ensures correct video rendering

# Step 7: Run MineRL (for headless environment, you should prepend vglrun to the command
python experiments/minerl044.py --image_width 64x64 --load simulation

To install vglrun, take a look at these guides:

• MineRL documentation
• Detailed Troubleshooting Guide

So, I tried installing on my windows system instead of the Ubuntu VM, and these were the exact steps I followed:

this is for MineRL-1.0.2, on Windows, using git bash

https://docs.google.com/document/d/1C0SI3YShkjO1t-yqURLVF_7Uj5ynvLqrDkMA8uZinqw/edit?usp=sharing

It was giving an error at the end that I couldn't figure out, saying:
Could not get unknown property 'jar' for task ':universalJar' of type org.gradle.api.tasks.bundling.Jar.

However, I tried running "pip install git+https://github.com/minerllabs/minerl"
instead of "pip install git+https://github.com/minerllabs/[email protected]" and that seemed to work.
I guess it's because minerl-1.0.2 is working, but not 1.0.0?

[Miffyli]

@lukedoma1 Yup! v1.0.0 installation does not work. Was this an instruction somewhere outside github issues (e.g,. on a webpage/readme)? That needs to be fixed :)

[lukedoma1]

@Miffyli I was following the install command on this page: https://minerl.readthedocs.io/en/latest/notes/versions.html
Not realizing there was anything after v1.0.0

[Miffyli]

Thanks! I have updated the instructions (will take some time for it to reflect on the live site) :)
