2021-10-28 Meeting notes

Andrew

• Debugging :Calculate in range size that ended up in undefined value - code in two places - test case and code both need to be fixed - PR sent Test for case of undefined behaviour and throw error if found by elfringham · Pull Request #52707 · tensorflow/tensorflow

• Gone on to AIA-44 - works when run by itself on thunderX2, failed in the docker container

• TensorFlow 2.7.0-rc1 uploaded to PyPi

Crefeda

• Talked to Google about some of the buginizer feedback - suggestion that it is probably best to continue to raise via GitHub issues
  
  

Theo

• Continue to look at AIA-43 - accuracy errors, issue posted to community git, response was to reduce the tolerance, posted a follow up with that fix. Will post commit

Nathan

Aided Theo in his debug - working upstream had a number of things involving Power for Eigen

Takis

Nothing to report for today

Tom

Talked about the plan for additional releases, mainline, OneDNN/ACL versions. With the flag pending to allow a user to select at runtime which backend they’ll get the thought was to hold off posting the OneDNN/ACL version in the current or another PyPi project for the time being
