"""Simple transfer learning with an Inception v3 architecture model which
displays summaries in TensorBoard.
This example shows how to take a Inception v3 architecture model trained on
ImageNet images, and train a new top layer that can recognize other classes of
images.
The top layer receives as input a 2048-dimensional vector for each image. We
train a softmax layer on top of this representation. Assuming the softmax layer
contains N labels, this corresponds to learning N + 2048*N model parameters
corresponding to the learned biases and weights.
Here's an example, which assumes you have a folder containing class-named
subfolders, each full of images for each label. The example folder flower_photos
should have a structure like this:
~/flower_photos/daisy/photo1.jpg
~/flower_photos/daisy/photo2.jpg
...
~/flower_photos/rose/anotherphoto77.jpg
...
~/flower_photos/sunflower/somepicture.jpg
The subfolder names are important, since they define what label is applied to
each image, but the filenames themselves don't matter. Once your images are
prepared, you can run the training with a command like this:
bazel build third_party/tensorflow/examples/image_retraining:retrain && \
bazel-bin/third_party/tensorflow/examples/image_retraining/retrain \
--image_dir ~/flower_photos
You can replace the image_dir argument with any folder containing subfolders of
images. The label for each image is taken from the name of the subfolder it's
in.
This produces a new model file that can be loaded and run by any TensorFlow
program, for example the label_image sample code.
To use with TensorBoard:
By default, this script will log summaries to /tmp/retrain_logs directory
Visualize the summaries with this command:
tensorboard --logdir /tmp/retrain_logs

Cropping
~~~~~~~~
Cropping is done by placing a bounding box at a random position in the full
image. The cropping parameter controls the size of that box relative to the
input image. If it's zero, then the box is the same size as the input and no
cropping is performed. If the value is 50%, then the crop box will be half the
width and height of the input. In a diagram it looks like this:
< width >
+---------------------+
| |
| width - crop% |
| < > |
| +------+ |
| | | |
| | | |
| | | |
| +------+ |
| |
| |
+---------------------+
Scaling
~~~~~~~
Scaling is a lot like cropping, except that the bounding box is always
centered and its size varies randomly within the given range. For example if
the scale percentage is zero, then the bounding box is the same size as the
input and no scaling is applied. If it's 50%, then the bounding box will be in
a random range between half the width and height and full size.
Args:
flip_left_right: Boolean whether to randomly mirror images horizontally.
random_crop: Integer percentage setting the total margin used around the
crop box.
random_scale: Integer percentage of how much to vary the scale by.

# However, there is a case where it is impossible to construct a valid
# ArgSpec. Python requires arguments that have no default values must be
# defined before those with default values. ArgSpec structure is only valid
# when this presumption holds true because default values are expressed as a
# tuple of values without keywords and they are always assumed to belong to
# last K arguments where K is number of default values present.

"""Probability calibration with isotonic regression or sigmoid.
With this class, the base_estimator is fit on the train set of the
cross-validation generator and the test set is used for calibration.
The probabilities for each of the folds are then averaged
for prediction. In case that cv="prefit" is passed to __init__,
it is it is assumed that base_estimator has been
fitted already and all data is used for calibration. Note that
data for fitting the classifier and for calibrating it must be disjoint.
Read more in the :ref:`User Guide <calibration>`.
Parameters
----------
base_estimator : instance BaseEstimator
The classifier whose output decision function needs to be calibrated
to offer more accurate predict_proba outputs. If cv=prefit, the
classifier must have been fit already on data.
method : 'sigmoid' or 'isotonic'
The method to use for calibration. Can be 'sigmoid' which
corresponds to Platt's method or 'isotonic' which is a
non-parametric approach. It is not advised to use isotonic calibration
with too few calibration samples ``(<<1000)`` since it tends to overfit.
Use sigmoids (Platt's calibration) in this case.
cv : integer, cross-validation generator, iterable or "prefit", optional
Determines the cross-validation splitting strategy.
Possible inputs for cv are:
- None, to use the default 3-fold cross-validation,
- integer, to specify the number of folds.
- An object to be used as a cross-validation generator.
- An iterable yielding train/test splits.
For integer/None inputs, if ``y`` is binary or multiclass,
:class:`StratifiedKFold` used. If ``y`` is neither binary nor
multiclass, :class:`KFold` is used.
Refer :ref:`User Guide <cross_validation>` for the various
cross-validation strategies that can be used here.
If "prefit" is passed, it is assumed that base_estimator has been
fitted already and all data is used for calibration.
Attributes
----------
classes_ : array, shape (n_classes)
The class labels.
calibrated_classifiers_: list (len() equal to cv or 1 if cv == "prefit")
The list of calibrated classifiers, one for each crossvalidation fold,
which has been fitted on all but the validation fold and calibrated
on the validation fold.

callSync 'sync', 'async', 'off', or None.
If 'async', then calling methods will return a Request object
which can be used to inquire later about the result of the
method call.
If 'sync', then calling a method
will block until the remote process has returned its result
or the timeout has elapsed (in this case, a Request object
is returned instead).
If 'off', then the remote process is instructed _not_ to
reply and the method call will return None immediately.

If 'proxy', then the value returned when calling a method
will be a proxy to the object on the remote process.
If 'value', then attempt to pickle the returned object and
send it back.
If 'auto', then the decision is made by consulting the
'noProxyTypes' option.
autoProxy bool or None. If True, arguments to __call__ are
automatically converted to proxy unless their type is
listed in noProxyTypes (see below). If False, arguments
are left untouched. Use proxy(obj) to manually convert
arguments before sending.
timeout float or None. Length of time to wait during synchronous
requests before returning a Request object instead.
deferGetattr True, False, or None.
If False, all attribute requests will be sent to the remote

received (or timeout has elapsed).
If True, requesting an attribute from the proxy returns a
new proxy immediately. The remote process is _not_ contacted

request an attribute that does not exist on the proxied
object. In this case, AttributeError will not be raised

"""
This class represents an attribute (or sub-attribute) of a proxied object.
It is used to speed up attribute requests. Take the following scenario::
rsys = proc._import('sys')
rsys.stdout.write('hello')
For this simple example, a total of 4 synchronous requests are made to
the remote process:
1) import sys
2) getattr(sys, 'stdout')
3) getattr(stdout, 'write')
4) write('hello')
This takes a lot longer than running the equivalent code locally. To
speed things up, we can 'defer' the two attribute lookups so they are
only carried out when neccessary::
rsys = proc._import('sys')
rsys._setProxyOptions(deferGetattr=True)
rsys.stdout.write('hello')
This example only makes two requests to the remote process; the two
attribute lookups immediately return DeferredObjectProxy instances
immediately without contacting the remote process. When the call
to write() is made, all attribute requests are processed at the same time.
Note that if the attributes requested do not exist on the remote object,
making the call to write() will raise an AttributeError.

Learn policy using PPO algorithm (https://arxiv.org/abs/1707.06347)
Parameters:
----------
network: policy network architecture. Either string (mlp, lstm, lnlstm, cnn_lstm, cnn, cnn_small, conv_only - see baselines.common/models.py for full list)
specifying the standard network architecture, or a function that takes tensorflow tensor as input and returns
tuple (output_tensor, extra_feed) where output tensor is the last network layer output, extra_feed is None for feed-forward
neural nets, and extra_feed is a dictionary describing how to feed state into the network for recurrent neural nets.
See common/models.py/lstm for more details on using recurrent nets in policies
env: baselines.common.vec_env.VecEnv environment. Needs to be vectorized for parallel environment simulation.
The environments produced by gym.make can be wrapped using baselines.common.vec_env.DummyVecEnv class.
nsteps: int number of steps of the vectorized environment per update (i.e. batch size is nsteps * nenv where
nenv is number of environment copies simulated in parallel)
total_timesteps: int number of timesteps (i.e. number of actions taken in the environment)
ent_coef: float policy entropy coefficient in the optimization objective
lr: float or function learning rate, constant or a schedule function [0,1] -> R+ where 1 is beginning of the
training and 0 is the end of the training.
vf_coef: float value function loss coefficient in the optimization objective
max_grad_norm: float or None gradient norm clipping coefficient
gamma: float discounting factor
lam: float advantage estimation discounting factor (lambda in the paper)
log_interval: int number of timesteps between logging events
nminibatches: int number of training minibatches per update. For recurrent policies,
should be smaller or equal than number of environments run in parallel.
noptepochs: int number of training epochs per update
cliprange: float or function clipping range, constant or schedule function [0,1] -> R+ where 1 is beginning of the training
and 0 is the end of the training
save_interval: int number of timesteps between saving events
load_path: str path to load the model from
**network_kwargs: keyword arguments to the policy / network builder. See baselines.common/policies.py/build_policy and arguments to a particular type of network
For instance, 'mlp' network architecture has arguments num_hidden and num_layers.

instead be passed as the session master and no ClusterSpec propagation
will be done. In the future, this may also support a list of strings

zone: Zone where the TPUs are located. If omitted or empty, we will assume
that the zone of the TPU is the same as the zone of the GCE VM, which we
will try to discover from the GCE metadata service.
project: Name of the GCP project containing Cloud TPUs. If omitted or
empty, we will try to discover the project name of the GCE VM from the
GCE metadata service.
job_name: Name of the TensorFlow job the TPUs belong to.
coordinator_name: The name to use for the coordinator. Set to None if the
coordinator should not be included in the computed ClusterSpec.
coordinator_address: The address of the coordinator (typically an ip:port
pair). If set to None, a TF server will be started. If coordinator_name
is None, a TF server will not be started even if coordinator_address is
None.
credentials: GCE Credentials. If None, then we use default credentials
from the oauth2client
service: The GCE API object returned by the googleapiclient.discovery
function. If you specify a custom service object, then the credentials
parameter will be ignored.
discovery_url: A URL template that points to the location of
the discovery service. It should have two parameters {api} and
{apiVersion} that when filled in produce an absolute URL to the
discovery document for that service. The environment variable
'TPU_API_DISCOVERY_URL' will override this.

Module containing various date parsing related utility functions.
All the functions for parsing dates in RFC3339 format have been optimized for performance since
they are part of a critical code path when ingesting Docker / Kubernetes logs.
Per micro benchmarks (benchmarks/micro/test_date_parsing.py), "udatetime" based implementations are
the fastest.
All the functions also support time formats in arbitrary timezones (aka non-UTC), but non-udatetime
pure Python versions fall back on python-dateutil which is rather slow. Luckily the common case and
code path is UTC where we can skip that code path.
It's also worth noting that our custom implementations also supports some extended formats which are
not fully valid as per RFC (e.g. very long fractional part). Because of that, some compatibility
change needed to be implemented for udatetime implementation as well and that adds small amount of
overhead.

"""Thin wrapper of CUDA Driver API.
There are four differences compared to the original C API.
1. Not all functions are ported.
2. Errors are translated into CUDADriverError exceptions.

Command handler
This module contains the infrastructure for accepting commands on the
command line. The processing of a command works as follows:
1. The calling object (caller) is analyzed based on its callertype.
2. Cmdsets are gathered from different sources:
- channels: all available channel names are auto-created into a cmdset, to allow
for giving the channel name and have the following immediately
sent to the channel. The sending is performed by the CMD_CHANNEL
system command.
- object cmdsets: all objects at caller's location are scanned for non-empty
cmdsets. This includes cmdsets on exits.
- caller: the caller is searched for its own currently active cmdset.
- player: lastly the cmdsets defined on caller.player are added.
3. The collected cmdsets are merged together to a combined, current cmdset.
4. If the input string is empty -> check for CMD_NOINPUT command in
current cmdset or fallback to error message. Exit.
5. The Command Parser is triggered, using the current cmdset to analyze the
input string for possible command matches.
6. If multiple matches are found -> check for CMD_MULTIMATCH in current
cmdset, or fallback to error message. Exit.
7. If no match was found -> check for CMD_NOMATCH in current cmdset or
fallback to error message. Exit.
8. A single match was found. If this is a channel-command (i.e. the
ommand name is that of a channel), --> check for CMD_CHANNEL in
current cmdset or use channelhandler default. Exit.
9. At this point we have found a normal command. We assign useful variables to it that
will be available to the command coder at run-time.
12. We have a unique cmdobject, primed for use. Call all hooks:
`at_pre_cmd()`, `cmdobj.parse()`, `cmdobj.func()` and finally `at_post_cmd()`.
13. Return deferred that will fire with the return from `cmdobj.func()` (unused by default).

Gather all relevant cmdsets and merge them.
Args:
caller (Session, Player or Object): The entity executing the command. Which
type of object this is depends on the current game state; for example
when the user is not logged in, this will be a Session, when being OOC
it will be a Player and when puppeting an object this will (often) be
a Character Object. In the end it depends on where the cmdset is stored.
session (Session or None): The Session associated with caller, if any.
player (Player or None): The calling Player associated with caller, if any.
obj (Object or None): The Object associated with caller, if any.
callertype (str): This identifies caller as either "player", "object" or "session"
to avoid having to do this check internally.
sessid (int, optional): Session ID. This is not used at the moment.
Returns:
cmdset (Deferred): This deferred fires with the merged cmdset
result once merger finishes.
Notes:
The cdmsets are merged in order or generality, so that the
Object's cmdset is merged last (and will thus take precedence
over same-named and same-prio commands on Player and Session).

Args:
called_by (Session, Player or Object): Object from which this
command was called. which this was called from. What this is

raw_string (str): The command string as given on the command line.
_testing (bool, optional): Used for debug purposes and decides if we
should actually execute the command or not. If True, the
command instance will be returned.
callertype (str, optional): One of "session", "player" or
"object". These are treated in decending order, so when the
Session is the caller, it will merge its own cmdset into
cmdsets from both Player and eventual puppeted Object (and
cmdsets in its room etc). A Player will only include its own
cmdset and the Objects and so on. Merge order is the same
order, so that Object cmdsets are merged in last, giving them
precendence for same-name and same-prio commands.
sessid (int, optional): Relevant if callertype is "player" - the session id will help
retrieve the correct cmdsets from puppeted objects.
Kwargs:
kwargs (any): other keyword arguments will be assigned as named variables on the
retrieved command object *before* it is executed. This is unused
in default Evennia but may be used by code to set custom flags or
special operating conditions for a command as it executes.
