Troubleshooting Install and upgrade Label Studio

Run the latest version of Label Studio

Many bugs might be fixed in patch releases or maintenance releases. Make sure you’re running the latest version of Label Studio by upgrading your installation before you start Label Studio.

Errors about missing packages

If you see errors about missing packages, install those packages and try to install Label Studio again. Make sure that you run Label Studio in a clean Python environment, such as a virtual environment.

For Windows users the default installation might fail to build the lxml package. Consider manually installing it from the unofficial Windows binaries. If you are running Windows 64-bit with Python 3.8 or later, run pip install lxml‑4.5.0‑cp38‑cp38‑win_amd64.whl to install it.

Errors from Label Studio

If you see any other errors during installation, try to rerun the installation.
