Are you familiar with the plugin system in tutor?
Basically, you will need to create a tutor plugin to add RUN pip install lti_consumer_xblock >3.5 to the openedx docker image AFTER the requirements have been installed (i.e. to override the default installation of lti_consumer_xblock ), hence the [specific patch](https://{{ patch(“openedx-dockerfile-post-python-requirements”) }}).
I think you can also use OPENEDX_EXTRA_PIP_REQUIREMENTS in your config.yml. That’s probably a better option. Once you configure it, you will need to rebuild the openedx image tutor images build openedx.
