+
+A TensorFlow `Session` for use in interactive contexts, such as a shell.
+
+The only difference with a regular `Session` is that an `InteractiveSession`
+installs itself as the default session on construction.
+The methods [`Tensor.eval()`](framework.md#Tensor.eval) and
+[`Operation.run()`](framework.md#Operation.run) will use that session
+to run ops.
+
+This is convenient in interactive shells and [IPython
+notebooks](http://ipython.org), as it avoids having to pass an explicit
+`Session` object to run ops.
+
+For example:
+
+```python
+sess = tf.InteractiveSession()
+a = tf.constant(5.0)
+b = tf.constant(6.0)
+c = a * b
+# We can just use 'c.eval()' without passing 'sess'
+print c.eval()
+sess.close()
+```
+
+Note that a regular session installs itself as the default session when it
+is created in a `with` statement.  The common usage in non-interactive
+programs is to follow that pattern:
+
+```python
+a = tf.constant(5.0)
+b = tf.constant(6.0)
+c = a * b
+with tf.Session():
+  # We can also use 'c.eval()' here.
+  print c.eval()
+```
+
+- - -
+
+#### tf.InteractiveSession.__init__(target='', graph=None) {#InteractiveSession.__init__}
+
+Creates a new interactive TensorFlow session.
+
+If no `graph` argument is specified when constructing the session,
+the default graph will be launched in the session. If you are
+using more than one graph (created with `tf.Graph()` in the same
+process, you will have to use different sessions for each graph,
+but each graph can be used in multiple sessions. In this case, it
+is often clearer to pass the graph to be launched explicitly to
+the session constructor.
+
+##### Args:
+
+
+*  <b>target</b>: (Optional.) The execution engine to connect to.
+    Defaults to using an in-process engine. At present, no value
+    other than the empty string is supported.
+*  <b>graph</b>: (Optional.) The `Graph` to be launched (described above).
