TransformerEngine is pre-built and packaged inside the containers with examples available at ``/opt/transformerengine`` or ``/opt/transformer-engine``. If you would like to use examples from TE main branch and are running into import errors, please try the latest pip package or building from source, although NGC containers are recommended for ease-of-use for most users.
