Hi @TareHimself!

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!

Thanks! This change makes sense and should make it more robust. Can you update to resolve the one lingering lint issue? I'm happy to merge it once the mandatory lint job is green.

[TareHimself]

How do I resolve the lint issue ? not sure how to run the linter locally

[TareHimself]

Also, does the CI succeeding mean it works with conda? I expect it to, just want to make sure

[GregoryComer]

@TareHimself Sure. For the local lintrunner, here's the setup and run commands: https://github.com/pytorch/executorch/blob/main/CONTRIBUTING.md#lintrunner. Regarding conda, we do use conda for most of the CI jobs, so if CI is passing, it should be good.
