tutorial: inside tensorflow eager execution runtime

introduction to eager execution

eager execution is an imperative programming environment that evaluates operations immediately, returning concrete values instead of constructing computational graphs to run later. this makes debugging and developing tensorflow models more intuitive and straightforward, similar to standard python code execution.

enabling eager execution

in tensorflow 2.x, eager execution is enabled by default. if you're using tensorflow 1.x, you'll need to enable it manually. here's how you can do that:



basic operations in eager execution

in eager execution, you can perform tensor operations just like you would in numpy. here’s a simple example to demonstrate this:



the eager execution environment

when you run operations in eager execution, tensorflow immediately computes the result. this is different from graph execution, where you would first define a computation graph and then run it in a session.

in eager mode, tensorflow maintains a dynamic computation graph. this means that the graph is created on-the-fly as operations are executed, allowing for more flexibility in model building and debugging.

using gradient tape

one of the key features of eager execution is the ability to compute gradients dynamically using `tf.gradienttape`. this is particularly useful for training models. here’s a simple example of how to use it:



debugging in eager execution

with eager execution, you can use standard python debugging techniques. you can use print statements, python debuggers (like `pdb`), and even jupyter notebooks for interactive exploration.

advantages of eager execution

1. **immediate feedback**: you can see the results of your computations as soon as you run the code.
2. **simplified debugging**: easier to debug with standard python tools and techniques.
3. **flexibility**: dynamic computation graphs allow for more flexible model architectures.
4. **integration with numpy**: ...
