Gradientzoo python bindings
Project description
Gradientzoo Python bindings
===========================
.. image:: https://readthedocs.org/projects/python-gradientzoo/badge/?version=latest
:target: http://python-gradientzoo.readthedocs.org/en/latest/?badge=latest
:alt: Documentation Status
This is a Python library for Gradientzoo's API - Version and share your trained
neural network models. Loading a pre-trained neural network is easy with
Gradientzoo. Here's how easy it is to load a model with Tensorflow (full
example below):
.. code:: python
import tensorflow as tf
from gradientzoo.tensorflow import TensorflowGradientzoo
# (build MNIST graph here)
with tf.Session() as sess:
# Load latest weights from Gradientzoo
TensorflowGradientzoo('ericflo/mnist').load(sess)
# Graph is now ready to use!
Saving models is similarly straightforward:
.. code:: python
import tensorflow as tf
from gradientzoo import TensorflowGradientzoo
# (build MNIST graph here)
with tf.Session() as sess:
for epoch in xrange(6):
# Train the model...
# Save the updated weights out to Gradientzoo
TensorflowGradientzoo('ericflo/mnist').save(sess)
Features
--------
Supports saving models in Keras_, variables in Tensorflow_, and networks in Lasagne_, and regular old files using Python with your framework of choice.
Installation
------------
You don't need this source code unless you want to modify the
package. If you just want to use the Gradientzoo Python bindings, you
should run:
pip install --upgrade gradientzoo
or
easy_install --upgrade gradientzoo
See http://www.pip-installer.org/en/latest/index.html for instructions
on installing pip. If you are on a system with easy_install but not
pip, you can use easy_install instead. If you're not using virtualenv,
you may have to prefix those commands with `sudo`. You can learn more
about virtualenv at http://www.virtualenv.org/
To install from source, run:
python setup.py install

Full Tensorflow Example
-----------------------
.. code:: python
import tensorflow as tf
from tensorflow.examples.tutorials.mnist import input_data, mnist
from gradientzoo.tensorflow import TensorflowGradientzoo
learning_rate = 0.01
batch_size = 100
# Build MNIST graph
images_placeholder = tf.placeholder(tf.float32,
shape=(batch_size, mnist.IMAGE_PIXELS))
labels_placeholder = tf.placeholder(tf.int32, shape=(batch_size))
logits = mnist.inference(images_placeholder, 128, 32)
loss = mnist.loss(logits, labels_placeholder)
train_op = mnist.training(loss, learning_rate)
eval_correct = mnist.evaluation(logits, labels_placeholder)
# Start a Tensorflow session
with tf.Session() as sess:
# Load latest weights from Gradientzoo
TensorflowGradientzoo('ericflo/mnist').load(sess)
# Read in some data
data_sets = input_data.read_data_sets('data', False)
# Test the trained network on the dataset
true_count = 0
for step in xrange(data_sets.test.num_examples // batch_size):
images_feed, labels_feed = data_sets.test.next_batch(batch_size, False)
true_count += sess.run(eval_correct, feed_dict={
images_placeholder: images_feed,
labels_placeholder: labels_feed,
})
precision = true_count / float(data_sets.test.num_examples)
print('Num Examples: %d Num Correct: %d Precision: %0.04f' %
(data_sets.test.num_examples, true_count, precision))
