MLiS2 VM Setup Guide — PiCar Kaggle Challenge

1. SSH into the Machine

ssh [uni username]@mlis2.nottingham.ac.uk

2. Install Anaconda

bash /shared/Anaconda3-2024.10-1-Linux-x86_64.sh

% Why not miniconda?

  • Press ENTER to confirm default install location (/home/[uni username]/anaconda3)
  • Type yes when asked to initialize conda
  • Then run:
source ~/.bashrc

3. Create Conda Environment

conda create --name picar2 python=3.9 -y
conda activate picar2

4. Install Dependencies

pip install numpy pandas matplotlib scikit-learn opencv-python pillow tensorflow kaggle

5. Set Up Kaggle API

Get your API token from kaggle.com → Settings → API → Generate New Token, then:

export KAGGLE_API_TOKEN=KGAT_xxxxxxxxxxxxxxxxxxxx

To make it persist across sessions:

echo 'export KAGGLE_API_TOKEN=KGAT_xxxxxxxxxxxxxxxxxxxx' >> ~/.bashrc

6. Download Competition Data

mkdir -p ~/picar-kaggle/data
kaggle competitions download -c machine-learning-in-science-ii-2026
unzip machine-learning-in-science-ii-2026.zip -d ~/picar-kaggle/data/

% fix this to save data into project, where scripts expect it

7. Set Up SSH Key for GitHub

ssh-keygen -t ed25519 -C "your_email@example.com"

Press Enter for all prompts (default location, no passphrase). Then copy the public key:

cat ~/.ssh/id_ed25519.pub

Copy the entire output line, go to github.com → Settings → SSH and GPG keys → New SSH key, paste it in, and save.

Test the connection:

ssh -T git@github.com

Type yes when prompted about host authenticity. You should see: Hi <username>! You've successfully authenticated...

8. Clone the Repo & Copy Data

cd ~
git clone git@github.com:lldvdll/PiCar.git
cd PiCar
cp -r ~/picar-kaggle/data/ ./data/

Watch for nested folders — cp -r can create data/data/. Fix with:

mv data/data/* data/
rmdir data/data

Also check for double-nested image folders (training_data/training_data/).

9. Configure Git

git config --global user.email "your_email@example.com"
git config --global user.name "Ningqian"

Set remote to SSH (if cloned via HTTPS):

git remote set-url origin git@github.com:lldvdll/PiCar.git

Reconnecting After Disconnect

Every time you reconnect to the VM:

source ~/.bashrc
conda activate picar2
cd ~/PiCar
