With our accrued experience with GANs, we would like to guide you through the required steps to go from theory to production with this revolutionary technology.

Starting from the very basic of what a GAN is, passing trough TensorFlow implementation, using the most cutting edge APIs available in the framework, and finally, production-ready serving at scale using Google Cloud Functions.

This is the ZURU Tech way of making GANs: enjoy it.

This tutorial requires the following packages:

• python >= 3.7
• tensorflow >=2.0: https://www.tensorflow.org/install/install_linux
• jupyter
• numpy

git clone https://github.com/zurutech/gans-from-theory-to-production
cd gans-from-theory-to-production

• virtualenv: virtualenv venv && source venv/bin/activate

pip install -r no-gpu-requirements.txt
# or pip install -r gpu-requirements if a GPU with Compute Capability >= 3.0 is present

jupyter notebook . or the newer jupyter lab ..

If you're here, you're ready to go.

Happy workshop!
