+# TensorFlow Experimental SessionRunHooks
+
+These hooks complement those in tensorflow/python/training. They are instances
+of `SessionRunHook` and are to be used with helpers like `MonitoredSession`
+and `learn.Estimator` that wrap `tensorflow.Session`.
+
+The hooks are called between invocations of `Session.run()` to perform custom
+behaviour.
+
+For example the `ProfilerHook` periodically collects `RunMetadata` after
+`Session.run()` and saves profiling information that can be viewed in a
+neat timeline through a Chromium-based web browser (via
+[about:tracing](chrome://tracing)) or the standalone [Catapult](https://github.com/catapult-project/catapult/blob/master/tracing/README.md) tool.
+
+```python
+from tensorflow.contrib.hooks import ProfilerHook
+
+hooks = [ProfilerHook(save_secs=30, output_dir="profiling")]
+with SingularMonitoredSession(hooks=hooks) as sess:
+  while not sess.should_stop():
+    sess.run(some_op)
+```
+
+Or similarly with contrib.learn:
+
+```python
+hooks = [ProfilerHook(save_steps=10, output_dir="profiling")]
+estimator = learn.Estimator(...)
+estimator.fit(input_fn, monitors=hooks)
+```

+## Imperative programming in TensorFlow
+
+In the standard TensorFlow library, the specification of the computation is done
+statically in terms of a computation graph, and is separate from the execution
+of the graph. This model of programming is referred to as *lazy*, *deferred*,
+*dynamic*, or, *asynchronous*. This library brings imperative style programming (à
+la [NumPy](http://www.numpy.org)) to TensorFlow. Using this library, you can:
+
+* Write code in an imperative style: the results of the computation are available
+  right after the execution of a line of code.
+* Use TensorFlow operations on tensors, and get all the benefits of GPU
+  acceleration.
+* Include any Python control flow statements like `while` and `if` when
+  specifying the computation.
+* Perform automatic differentiation on your code with the
+  standard
+  [`tf.gradients`](https://www.tensorflow.org/api_docs/python/train/gradient_computation#gradients) function.
+
+### Getting started
+
+This library is a thin wrapper over the standard TensorFlow Python library. The
+source code is
+available
+[here](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/imperative). You
+can get started on Linux by installing the nightly PIP package linked off 
+[the main page](https://github.com/tensorflow/tensorflow). Please
+consult [this](https://github.com/tensorflow/tensorflow#installation) document for other platforms and the PIP package including GPU
+support.
+
+
+### Write your first imperative TensorFlow program
+
+```shell
+$ python
+```
+
+```python
+>>> import tensorflow.contrib.imperative as tf
+>>> x = tf.constant([[7.], [6]])
+>>> y = tf.constant([[6., 7]])
+>>> tf.matmul(x, y)
+array([[ 42.,  49.],
+       [ 36.,  42.]], dtype=float32)
+```
+
+Note that this code is identical in terms of the programmer's mental model to
+the following NumPy code:
+
+```python
+>>> import numpy as np
+>>> x = np.array([[7.], [6]])
+>>> y = np.array([[6., 7]])
+>>> x.dot(y)
+array([[ 42.,  49.],
+       [ 36.,  42.]])
+```
+
+The library can be imported as `import tensorflow.contrib.imperative as tf`
+(contrast with importing standard TensorFlow, which is done as `import
+tensorflow as tf`). This import statement makes all of standard TensorFlow
+available in the `tf` symbol. However, it is not necessary to create a session
+object and set it up to run and fetch tensors.
+
+
+### Features
+
+The library provides the following additional features on top of standard
+TensorFlow:
+
+* Tensors are automatically fetched when used in contexts that expect their
+  value.
+
+  - Printing
+
+  ```python
+  x = tf.constant(10)
+  y = tf.constant(32)
+  print(x + y)
+  42
+  ```
+
+  - Use in conditionals
+
+  ```python
+  x = tf.constant(30)
+  if x > 4:
+    print('Greater than 4')
+  Greater than 4
+
+  x = tf.random_normal([3])
+  y = x * 2
+  while tf.global_norm([y]) < 1000:
+    y = y * 2
+  print(y)
+  [ -213.2868042   -511.02456665  1026.66882324]
+  ```
+
+* Variables are automatically initialized, no need to run the
+  [`tf.global_variables_initializer()`](https://www.tensorflow.org/api_docs/python/state_ops/variable_helper_functions#global_variables_initializer) operation.
+
+  ```python
+  x = tf.Variable(np.random.normal(size=[2, 2]), dtype=tf.float32)
+  y = tf.constant([[1, 2.]])
+  z = tf.matmul(y, x)
+  print(z)
+  array([[-1.231673  ,  3.14744973]], dtype=float32)
+  ```
+
+* Gradients work as expected using the standard `tf.gradients` function.
+
+   ```python
+   x = tf.Variable(np.random.rand(1, 3))
+   y = tf.exp(x)
+   dy = tf.gradients(y, x)
+   # dy/dx should be equal to y (= exp(x))
+   print(y, dy)
+   (array([[ 1.79997761,  2.00581881,  2.37302414]]), [array([[ 1.79997761,  2.00581881,  2.37302414]])])
+   ```
+
+### Caveats
+
+The library is implemented on top of standard TensorFlow. It still constructs a
+graph in the background and defers op execution. But when an op executes for the
+first time, its results are cached and the cached value is returned for future
+executions, thus providing imperative semantics. Because of this implementation
+choice, this library comes with the following caveats:
+
+* **Use inside Python loops:** A graph is constructed and kept around in
+  the background, both for just executing using the standard TensorFlow runtime,
+  and also for allowing automatic differentiation via `tf.gradients`. This means
+  that the graph keeps growing when TensorFlow functions are called inside a
+  Python loop. This library provides a `tf.new_step` method that clears the
+  graph as well as the cached tensors that have been kept around for gradient
+  computation. `tf.new_step` can be used as a context manager around, say, a
+  training loop to clear the graph after each training step.
+
+  ```python
+  x = tf.Variable(constant_op.constant(1.0))
+  for i in range(10):
+    # Create a new training step
+    with tf.new_step() as step:
+      # Perform computation and variable updates
+      step.run(tf.assign_sub(x, 0.1))
+      self.assertAllClose(tf.identity(x), 1.0 - (i + 1) * 0.1)
+      # The graph within this context is cleared at this point.
+  ```
+
+* **Speed:** Redundant graph construction and caching of tensor values adds
+  overheads that are not present in standard TensorFlow, where typically the
+  graph is constructed once and executed multiple times. This library is
+  intended as a vehicle to prototype the imperative programming model in
+  TensorFlow. The runtime overheads can be alleviated with various optimizations
+  to the runtime that would equally benefit the deferred execution mode as
+  well.

-    1. This function uses substring matching, i.e. the matching

-    3. Use regexes=[''] for a regex that will always pass.

-    4. '.' matches any single character *except* the newline.  To
-       match any character, use '(.|
-)'.
-
-    5. '^' matches the beginning of each line, not just the beginning
-       of the string.  Similarly, '$' matches the end of each line.

-       regex.

-
-Asserts that at least one regex in regexes matches str.

-    If possible you should use assertRegexpMatches, which is a simpler
-    version of this method. assertRegexpMatches takes a single regular
-    expression (a string or re compiled object) instead of a list.
-
-    Notes:
-    1. This function uses substring matching, i.e. the matching
-       succeeds if *any* substring of the error message matches *any*
-       regex in the list.  This is more convenient for the user than
-       full-string matching.
-
-    2. If regexes is the empty list, the matching will always fail.
-
-    3. Use regexes=[''] for a regex that will always pass.
-
-    4. '.' matches any single character *except* the newline.  To
-       match any character, use '(.|
-)'.
-
-    5. '^' matches the beginning of each line, not just the beginning
-       of the string.  Similarly, '$' matches the end of each line.
-
-    6. An exception will be thrown if regexes contains an invalid
-       regex.

-      actual_str:  The string we try to match with the items in regexes.
