How do I disable TensorFlow's eager execution?

Question

I am trying to learn TensorFlow. Currently, I am working with placeholders. When I tried to create the placeholder, I got an error: RuntimeError: tf.placeholder() is not compatible with eager execution, which makes sense as placeholders are not executable immediately.

So, how do I turn eager execution off?

I have never turned eager execution on in the first place, so I am not sure how it happened. Is there an opposite to tf.disable_eager_execution()?

Answer 1

Assume you are using Tensorflow 2.0 preview release which has eager execution enabled by default. There is a disable_eager_execution() in v1 API, which you can put in the front of your code like:

import tensorflow as tf

tf.compat.v1.disable_eager_execution()

On the other hand, if you are not using 2.0 preview, please check if you accidentally enabled eager execution somewhere.
