Hi @denadai2!
Thank you for your pull request and welcome to our community.
Action Required
In order to merge any pull request (code, docs, etc.), we require contributors to sign our Contributor License Agreement, and we don't seem to have one on file for you.
Process
In order for us to review and merge your suggested changes, please sign at https://code.facebook.com/cla. If you are contributing on behalf of someone else (eg your employer), the individual CLA may not be sufficient and your employer may need to sign the corporate CLA.
Once the CLA is signed, our tooling will perform checks and validations. Afterwards, the pull request will be tagged with CLA signed
. The tagging process may take up to 1 hour after signing. Please give it that time before contacting us about it.
If you have received this in error or have any questions, please contact us at [email protected]. Thanks!
Hi @denadai2 thanks for the PR! Actually this utility is not used in any of our recipes (code search shows it's only in the unit test and init file). So I think this is dead code anyways. In fact we don't really support mixed precision training and instead prefer to use true bf16 training, which requires less memory. Let me know if this makes sense
