@imprasshant I've encountered same problem. That's because original FLAGS is replaced with abseil's one. If you want to use original one, you need to use tensorflow

@rickyhai11 You can simply use `argparse` module in Python instead of tf.FLAGS. Here is the [reference code](https://gist.github.com/coffeedjimmy/11a4097d43c3d8c8c6eceb798c5ee325) for better understanding.
