 | # NOTE: 2022-05-27: protobuf 4.21.0, released on May 25, 2022 is incompatible | 
 | # with prior releases. Specifically implicated are the above versions of | 
 | # tensorflow, which seem to include it without a version pin and therefore | 
 | # break out of the box. The next time the above versions are upgraded, | 
 | # try removing this line and then, within the docker image, run: | 
 | #   python3 -c "import tensorflow" | 
 | # If that fails with a stack trace, put this line back. | 
 | # On behalf of Google, we are sorry for the live at head philosophy | 
 | # and shoddy version management leaking into everything. We're victims too. | 
 | protobuf>=3.20.1, <4 |
