  +## Feature Prioritization Survey
  +
  +The TensorFlow team is working on building/improving features, and understands that it is very important to prioritize these efforts based on what TF users need.
  +
  +The goal of this short, < 5min [survey](https://google.qualtrics.com/jfe/form/SV_d5nqhCEbkDkQ7ad), is to help the TensorFlow team better understand what features to prioritize based on your feedback. Participation is of course optional.
  +
  +Take the survey [HERE](https://google.qualtrics.com/jfe/form/SV_d5nqhCEbkDkQ7ad).
