 2) Create a virtual environment and install the project in it. From the root of `torchjd`, run:
    ```bash

+   CC=gcc uv pip install --python-version=3.13.3 -e '.[full]' --group check --group doc --group test --group plot
+   ```
+   We also advise using `UV_NO_SYNC=1` to prevent `uv` from syncing all the time. This is because by
+   default, it tries to resolve libraries compatible with the whole range of Python versions
+   supported by TorchJD, but in reality, we just need an installation compatible with the currently
+   used Python version. That's also why we specify `--python-version=3.14` when running
+   `uv pip install`. To follow that recommendation, add the following line to your `.bashrc`:
+   ```bash
+   export UV_NO_SYNC=1
+   ```
+   and start a new terminal. The alternative is to use the `--no-sync` flag whenever you run a pip
+   command that would normally sync (like `uv run`).
