Uninstall Transformer Lab

Uninstall Application:​

  • MacOS: Delete the Transformer Lab application from your /Applications Folder
  • Windows: Uninstall the Application
  • Linux: Delete the App whereever you stored it

Stored Data:​

  • Transformer Lab stores models and data in your ~/.transformerlab/ folder -- deleting everything there will destroy all your settings and experiments
  • On MacOS, there may be a small folder in ~/Library/Logs/transformerlab/

For MacOS, here is a script you can run in a Terminal that will do all of the above steps:

rm -rf /Applications/Transformer\ Lab.app/
rm -rf ~/.transformerlab/
rm -rf ~/Library/Logs/transformerlab/

This will remove all the packages installed for Transformer Lab, freeing up space.

Clear Python Cache:​

Transformer Lab uses uv to install Python packages. You may also want to clear the uv cache. Instructions are below:

Delete Models and Datasets:​

Most models and datasets that are downloaded in Transformer Lab are downloaded using Hugging Face Hub which stores them at ~/.cache/huggingface/hub. Delete this directory to remove the large model files, unless you want them available to other applications.
