+# Pointer Networks in Tensorflow
+
+TensorFlow implementation of [Pointer Networks](https://arxiv.org/abs/1506.03134).
+
+![model](./assets/model.png)
+
+(in progress)
+
+
+## Requirements
+
+- Python 2.7
+- [tqdm](httsp://github.com/tqdm/tqdm)
+- [TensorFlow 0.12.1](httsp://github.com/tensorflow/tensorflow/tree/r0.12)
+
+
+## Usage
+
+To train a model:
+
+    $ python main.py --task=tsp20 --lr_start=0.001 --min_data_length=5 --max_data_length=20
+    $ python main.py --task=tsp50 --lr_start=0.001 --min_data_length=5 --max_data_length=50
+    $ python main.py --task=tsp100 --lr_start=0.0001 --min_data_length=5 --max_data_length=100
+
+
+To train a model:
+
+    $ python main.py
+    $ tensorboard --logdir=logs --host=0.0.0.0
+
+To test a model:
+
+    $ python main.py --is_train=False
+
+## Results
+
+(in progress)
+
