How to Convert a TensorFlow x Code to TensorFlow x

Ready to leverage the power and simplicity of TensorFlow 2.x but stuck with your existing 1.x code? Don’t worry upgrading is easier than you think! Here’s a step-by-step guide to get you started.

1. Install TensorFlow 2.x

First things first, equip your toolbox with the latest edition. Use pip or conda to install TensorFlow 2.x. For example , with pip :

pip install tensorflow

2. Run the Upgrade Script

Time to wave the magic wand! TensorFlow provides a handy script to automate much of the conversion.

Find it on the TensorFlow GitHub repository or use the command line :

tf_upgrade_v2 --infile tf1_code.py --outfile tf2_code.py

This script uses TensorFlow 2.x’s updated APIs and syntax to convert your tf1_code.py file to tf2_code.py. It also produces a report that highlights changes and areas that require your attention. You can also use the flag –reportfile report.txt to save the report to a file.

3. Fix the errors and warnings

Not all of the faults and warnings in your code may be resolved by the TensorFlow 2.x upgrade procedure. Some difficulties may need manual code editing, such as changing outdated APIs , eliminating sessions and placeholders, adding tf.function decorators, and so on.

4. Test your code

Once your code has been changed to TensorFlow 2.x , you should test it to ensure that it functions as intended. The same measurements and data as before may be used to compare the outcomes. Additionally , you may use tf.debugging , the TensorFlow 2.x debugger , to examine your code for faults and abnormalities.

The introduction of TensorFlow 2. x marks a significant advance in the strong open-source machine learning toolkit TensorFlow. TensorFlow 2.0 introduces significant API changes, making manual code upgrades tedious and error prone. TensorFlow 2. x places an emphasis on user-friendliness and optimizes the development process, whereas TensorFlow 1. x provided a versatile, low-level API.

Upgrading your current TensorFlow 1.x code to TensorFlow 2.x can provide you access to additional capabilities, faster processing, and a more user-friendly programming environment. The main ideas and procedures needed to successfully transition your TensorFlow 1.x code to TensorFlow 2.x will be covered in this post.

• TensorFlow 2.0 introduces significant API changes, making manual code upgrades tedious and error prone.
• The tf_upgrade_v2 utility simplifies the transition by automating most conversions.
• With manual adjustments:
  • Proofreading tf.compat.v1 usages and migrating them to the new tf.* namespace.
  • Handling deprecated modules like tf.flags by using alternatives like absl.flags or packages in tensorflow/addons.
