+
+    This method is a pass-through function that returns `the_value`, used to hint TorchScript
+    compiler the type of `the_value`. It is a no-op when running outside of TorchScript.
+
+    Though TorchScript can infer correct type for most Python expressions, there are some cases where

+
+    - Empty containers like `[]` and `{}`, which TorchScript assumes to be container of `Tensor`
+    - Optional types like `Optional[T]` but assigned a valid value of type `T`, TorchScript would assume
+      it is type `T` rather than `Optional[T]`
+
+    Note that `annotate()` does not help in `__init__` method of `torch.nn.Module` subclasses because it
+    is executed in eager mode. To annotate types of `torch.nn.Module` attributes,

+class AttributeTypeIsSupportedChecker(ast.NodeVisitor):
+    """Check the ``__init__`` method of a given ``nn.Module``.
+
+    It ensures that all instance-level attributes can be properly initialized.
+
+    Specifically, we do type inference based on attribute values...even
+    if the attribute in question has already been typed using
+    Python3-style annotations or ``torch.jit.annotate``. This means that
+    setting an instance-level attribute to ``[]`` (for ``List``),
+    ``{}`` for ``Dict``), or ``None`` (for ``Optional``) isn't enough
+    information for us to properly initialize that attribute.
+
+    An object of this class can walk a given ``nn.Module``'s AST and
+    determine if it meets our requirements or not.
+
+    Known limitations
+    1. We can only check the AST nodes for certain constructs; we can't
+    ``eval`` arbitrary expressions. This means that function calls,
+    class instantiations, and complex expressions that resolve to one of
+    the "empty" values specified above will NOT be flagged as
+    problematic.
+    2. We match on string literals, so if the user decides to use a
+    non-standard import (e.g. `from typing import List as foo`), we
+    won't catch it.
+
+    Example:
+        .. code-block:: python
+
+            class M(torch.nn.Module):
+                def fn(self):
+                    return []
+
+                def __init__(self) -> None:
+                    super().__init__()
+                    self.x: List[int] = []

+                    self.x = x
+                    return 1
+
+        The above code will pass the ``AttributeTypeIsSupportedChecker``
+        check since we have a function call in ``__init__``. However,
+        it will still fail later with the ``RuntimeError`` "Tried to set
+        nonexistent attribute: x. Did you forget to initialize it in
+        __init__()?".

+
+    Freezing a :class:`ScriptModule` will clone it and attempt to inline the cloned
+    module's submodules, parameters, and attributes as constants in the TorchScript IR Graph.
+    By default, `forward` will be preserved, as well as attributes & methods specified in
+    `preserved_attrs`. Additionally, any attribute that is modified within a preserved
+    method will be preserved.
+
+    Freezing currently only accepts ScriptModules that are in eval mode.
+
+    Freezing applies generic optimization that will speed up your model regardless of machine.
+    To further optimize using server-specific settings, run `optimize_for_inference` after
+    freezing.
+
+    Args:
+        mod (:class:`ScriptModule`): a module to be frozen
+        preserved_attrs (Optional[List[str]]): a list of attributes to preserve in addition to the forward method.

+            preserve numerics. Full details of optimization can be found at `torch.jit.run_frozen_optimizations`.
+
+    Returns:
+        Frozen :class:`ScriptModule`.

+

+
+    Usage: provide a list of pairs (type, depth) where type is one of "STATIC" or "DYNAMIC"
+    and depth is an integer.
+
+    Behavior - static vs dynamic:
+        In STATIC fusion, fused ops are compiled to have fixed input shapes. The shape is determined
+        based on some initial profiling runs.
+        In DYNAMIC fusion, fused ops are compiled to have variable input shapes, so that multiple
+        shapes are possible.
+
+    In both cases, we also recompile on new striding behavior, device, or dtype.
+
+    Behavior - fallback functions & depth:
+        When an input doesn't match the format required by the specialized compiled op, it will run
+        a fallback function. Fallback functions are recursively be compiled and specialized based
+        on the observed tensor shapes. Since compilation can be slow, the "depth" parameter is provided to
+        limit the number of specializations that can be compiled, before giving up on recompiling and
+        falling back to a completely un-fused, un-specialized implementation.
+
+    The list of (type, depth) pairs controls the type of specializations and the number of
+    specializations. For example: [("STATIC", 2), ("DYNAMIC", 2)] indicates that the first
+    two specializations will use static fusions, the following two specializations will use
+    dynamic fusion, and any inputs that satisfy none of the 4 options will run an
+    unfused implementation.
+
+    NB: in the future, if more as more fusion backends are added there may be more granular
+    apis for specific fusers.

+    Save an offline version of this module for use in a separate process.
+
+    The saved module serializes all of the methods, submodules, parameters, and
+    attributes of this module. It can be loaded into the C++ API using
+    ``torch::jit::load(filename)`` or into the Python API with
+    :func:`torch.jit.load <torch.jit.load>`.
+
+    To be able to save a module, it must not make any calls to native Python
+    functions.  This means that all submodules must be subclasses of
+    :class:`ScriptModule` as well.
+
+    .. DANGER::
+        All modules, no matter their device, are always loaded onto the CPU
+        during loading.  This is different from :func:`torch.load`'s semantics
+        and may change in the future.
+
+    Args:
+        m: A :class:`ScriptModule` to save.
+        f: A file-like object (has to implement write and flush) or a string
+           containing a file name.
+        _extra_files: Map from filename to contents which will be stored as part of `f`.
+
+    .. note::
+        torch.jit.save attempts to preserve the behavior of some operators
+        across versions. For example, dividing two integer tensors in
+        PyTorch 1.5 performed floor division, and if the module
+        containing that code is saved in PyTorch 1.5 and loaded in PyTorch 1.6
+        its division behavior will be preserved. The same module saved in
+        PyTorch 1.6 will fail to load in PyTorch 1.5, however, since the
+        behavior of division changed in 1.6, and 1.5 does not know how to
+        replicate the 1.6 behavior.
