ebf36ad3 - Remove travis-python references as well as some unnecessary dependencies (#47209)

Remove travis-python references as well as some unnecessary dependencies (#47209) Summary: This PR attempts to remove unneeded installations of `pip` among other packages in `install_base.sh` since these very same packages are already installed elsewhere (for example in `install_conda.sh`). In the process, I found some old `TRAVIS_PYTHON_VERSION` references that are no longer needed, so I removed all references that need `install_travis_python.sh` Pull Request resolved: https://github.com/pytorch/pytorch/pull/47209 Reviewed By: mruberry Differential Revision: D24690079 Pulled By: janeyx99 fbshipit-source-id: f8fef4cda9832c868595d4745d811fc7d42df34d
