Didn't tflearn become tensorflow.contrib.learn? So there's technically a high level API in the TF standard library. Though Keras would probably be a better choice if OP wanted a high level API for deep learning.
A version of Keras is included in Tensorflow since 1.1 as well, under `tensorflow.contrib.keras.python.keras`. (This has been particularly useful for me as a Windows user, since my GTX 1080 is stuck in a Windows machine, and it's a little more painful to deal with upstream Keras dependencies on Windows, but TF alone works great)
