Tensorflow 2: Getting “WARNING:tensorflow:9 out of the last 9 calls to function triggered tf.function”

If you are using Tensorflow 2 and have encountered the warning message “WARNING:tensorflow:9 out of the last 9 calls to function triggered tf.function”, don’t worry – you’re not alone. This warning message is quite common and can be easily resolved with a few simple steps.

To understand why this warning message is appearing, it’s important to know that Tensorflow 2 has introduced a new feature called tf.function. This feature is designed to automatically convert plain Python functions into optimized graph operations, improving the performance of your Tensorflow code. However, sometimes this feature can lead to unexpected behavior, such as the warning message mentioned above.

To address this warning message, you can try the following solutions:

1. Make sure you are using the latest version of Tensorflow 2. Upgrading to the latest version may resolve the issue.
2. If the warning message is not impacting the functionality of your code, you can simply ignore it. This warning message is primarily for informational purposes and does not necessarily indicate a problem with your code.
3. If the warning message is causing issues with your code, you can try manually disabling the tf.function feature for specific functions by decorating them with @tf.function(experimental_relax_shapes=True).

By following these steps, you should be able to resolve the warning message “WARNING:tensorflow:9 out of the last 9 calls to function triggered tf.function” in Tensorflow 2. Remember to always test your code thoroughly after making any changes to ensure everything is functioning as expected.
