tf.estimator.RunConfig does not parse environment variable TF_CONFIG. It only return the constants as below:

https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/estimator/run_config.py#L121-L151

We can not run distributed learning with tf.estimator ?

Answer 1

The functionality in tf.estimator is still be worked on, and does not contain the functionality to use the TF_CONFIG environment variable.

For now, please continue using tf.contrib Estimator APIs.
