Supported OS

Currently, we only support MacOS and Linux operating systems. Windows users have the possibility to install and use ivadomed via Windows Subsystem for Linux (WSL). The steps below (about updating bashrc) are strongly recommended for MacOS users in the installation process but are optional for Linux users.

Open your bash/zsh script file with editor on your computer.

If you are using bash shell

vim ~/.bashrc

If you are using zsh shell

vim ~/.zshrc

Write in your .bashrc/.zshrc file with following line.


Save this change and restart your terminal to apply the change.

There are fundamentally two different approaches to install IvadoMed:

  1. Install via Conda
    This is the easiest way for personal computers.
  2. Install via Venv/VirtualEnv
    This is compatible with ComputeCanada cluster environment.

Approach 1: Conda

Step 1: Clone the ivadomed repository.

git clone
cd ivadomed

Step 2: Create new Conda Env called IvadoMedEnv (may take 5 to 15 minutes)

conda env create --file environment.yml

Step 3 : Activate environment and use

conda activate IvadoMedEnv

Step 4 : Install from source

pip install -e .

Approach 2: Venv

Step 1: Setup Python Virtual Environment.

ivadomed requires Python >= 3.6 and <3.9 (If you are using Compute Canada, you can load modules (e.g. python 3.9) as mentioned here and also here ). We recommend working under a virtual environment, which could be set as follows:

virtualenv venv-ivadomed
source venv-ivadomed/bin/activate


If the default Python version installed in your system does not fit the version requirements, you might need to specify a version of Python associated with your virtual environment:

virtualenv venv-ivadomed --python=python3.6

Step 2: Clone the ivadomed repository.

git clone
cd ivadomed

Step 3: Install PyTorch 1.5 and TorchVision

If you have a compatible NVIDIA GPU that supports CUDA, run the following command:

pip install -r requirements_gpu.txt

If you do not have a compatible GPU, run the following installer to use ivadomed with CPU.

pip install -r requirements.txt

(Optional) Alternative Step 4 for Developers: Install from source

Bleeding-edge developments are available on the project’s master branch on Github. Installation procedure is the following at repository root:

cd ivadomed
pip install -e .

(Optional) Step 5 for Developers Install pre-commit hooks

We use pre-commit to enforce a limit on file size. After you’ve installed ivadomed, install the hooks:

pip install -r requirements_dev.txt
pre-commit install
