# fregion.py : read structured data files
#
# to load a file from the path P into the variable f:
# f = fregion.FRegion(P)
#
# to read the stored field 'x' out of f:
# f.x
#
# to read the 'metadata' for the field 'x' (type and offset details):
# meta(f).x
#
# There are 2 ways to add reading support for a custom user type:
# 1.
# fregion.FRegion.addType("MyTypeName", lambda renv, td, repty: makeMyTypeNameReader(renv,td,repty))
# where:
# 'renv' will be the "reader environment" (necessary for any call to makeReader)
# 'td' will be the full type description where "MyTypeName" appears at root (e.g. for 'fileref', App(Prim('fileref', ...), [Arr(Prim('char'))]))
# 'repty' will be the determined 'representation type' (which can also be determined through 'td')
# and:
# the returned 'reader' must be a class with a "read" function like:
# def read(self,m,o):
# where
# 'm' will give access to the memory for the file being read out of
# 'o' will be the memory offset where the value to be read is placed
# and:
# the returned value may be whatever the application decides is sensible
#
# 2. Just use the decorator RegReader like:
# @RegReader("MyTypeName")
# class MyTypeReader:
# def __init__(self, renv, ty, repty):
# pass
# def read(self, m, offset):
# pass

This version has support for both online L2 (the L2 penalty given in the paper

Update ($$i$$ is variable index):

r"""Construct a new FTRL optimizer.
Args:
learning_rate: A float value or a constant float `Tensor`.
learning_rate_power: A float value, must be less or equal to zero.
Controls how the learning rate decreases during training. Use zero for
a fixed learning rate.
initial_accumulator_value: The starting value for accumulators.
Only zero or positive values are allowed.
l1_regularization_strength: A float value, must be greater than or
equal to zero.
l2_regularization_strength: A float value, must be greater than or
equal to zero.
name: Optional name prefix for the operations created when applying
gradients. Defaults to "Ftrl".
l2_shrinkage_regularization_strength: A float value, must be greater than
or equal to zero. This differs from L2 above in that the L2 above is a
stabilization penalty, whereas this L2 shrinkage is a magnitude penalty.
The FTRL formulation can be written as:
w_{t+1} = argmin_w(\hat{g}_{1:t}w + L1*||w||_1 + L2*||w||_2^2), where
\hat{g} = g + (2*L2_shrinkage*w), and g is the gradient of the loss
function w.r.t. the weights w.
Specifically, in the absence of L1 regularization, it is equivalent to
the following update rule:
w_{t+1} = w_t - lr_t / (1 + 2*L2*lr_t) * g_t -
2*L2_shrinkage*lr_t / (1 + 2*L2*lr_t) * w_t
where lr_t is the learning rate at t.
When input is sparse shrinkage will only happen on the active weights.\
**kwargs: keyword arguments. Allowed to be {`clipnorm`, `clipvalue`, `lr`,
`decay`}. `clipnorm` is clip gradients by norm; `clipvalue` is clip
gradients by value, `decay` is included for backward compatibility to
allow time inverse decay of learning rate. `lr` is included for backward
compatibility, recommended to use `learning_rate` instead.
Raises:
ValueError: If one of the arguments is invalid.

TileStache/TileStache | TileStache/Config.py | 1 | 15616 | """ The configuration bits of TileStache.
TileStache configuration is stored in JSON files, and is composed of two main
top-level sections: "cache" and "layers". There are examples of both in this
minimal sample configuration:
{
"cache": {"name": "Test"},
"layers": {
"example": {
"provider": {"name": "mapnik", "mapfile": "examples/style.xml"},,
"projection": "spherical mercator"
}
}
}
The contents of the "cache" section are described in greater detail in the
TileStache.Caches module documentation. Here is a different sample:
"cache": {
"name": "Disk",
"path": "/tmp/stache",
"umask": "0000"
}
The "layers" section is a dictionary of layer names which are specified in the
URL of an individual tile. More detail on the configuration of individual layers
can be found in the TileStache.Core module documentation. Another sample:
{
"cache": ...,
"layers":
{
"example-name":
{
"provider": { ... },
"metatile": { ... },
"preview": { ... },
"stale lock timeout": ...,
"projection": ...
}
}
}
Configuration also supports these additional settings:
- "logging": one of "debug", "info", "warning", "error" or "critical", as
described in Python's logging module: http://docs.python.org/howto/logging.html
- "index": configurable index pages for the front page of an instance.
A custom index can be specified as a filename relative to the configuration
location. Typically an HTML document would be given here, but other kinds of
files such as images can be used, with MIME content-type headers determined
by mimetypes.guess_type. A simple text greeting is displayed if no index
is provided.
In-depth explanations of the layer components can be found in the module
documentation for TileStache.Providers, TileStache.Core, and TileStache.Geography.

原版代码：https://github.com/cleverdeng/pinyin.py
新增功能：
1、可以传入参数firstcode：如果为true，只取汉子的第一个拼音字母；如果为false，则会输出全部拼音；
2、修复：如果为英文字母，则直接输出；
3、修复：如果分隔符为空字符串，仍然能正常输出；
4、升级：可以指定词典的文件路径

"""Represents a dataset distributed among devices and machines.
A `tf.distribute.DistributedDataset` could be thought of as a "distributed"
dataset. When you use `tf.distribute` API to scale training to multiple
devices or machines, you also need to distribute the input data, which leads
to a `tf.distribute.DistributedDataset` instance, instead of a
`tf.data.Dataset` instance in the non-distributed case. In TF 2.x,
`tf.distribute.DistributedDataset` objects are Python iterables.
Note: `tf.distribute.DistributedDataset` instances are *not* of type
`tf.data.Dataset`. It only supports two usages we will mention below:
iteration and `element_spec`. We don't support any other APIs to transform or
inspect the dataset.
There are two APIs to create a `tf.distribute.DistributedDataset` object:
`tf.distribute.Strategy.experimental_distribute_dataset(dataset)`and
`tf.distribute.Strategy.distribute_datasets_from_function(dataset_fn)`.
*When to use which?* When you have a `tf.data.Dataset` instance, and the
regular batch splitting (i.e. re-batch the input `tf.data.Dataset` instance
with a new batch size that is equal to the global batch size divided by the
number of replicas in sync) and autosharding (i.e. the
`tf.data.experimental.AutoShardPolicy` options) work for you, use the former
API. Otherwise, if you are *not* using a canonical `tf.data.Dataset` instance,
or you would like to customize the batch splitting or sharding, you can wrap
these logic in a `dataset_fn` and use the latter API. Both API handles
prefetch to device for the user. For more details and examples, follow the
links to the APIs.
There are two main usages of a `DistributedDataset` object:
1. Iterate over it to generate the input for a single device or multiple
devices, which is a `tf.distribute.DistributedValues` instance. To do this,
you can:
* use a pythonic for-loop construct:
>>> global_batch_size = 4
>>> strategy = tf.distribute.MirroredStrategy(["GPU:0", "GPU:1"])
>>> dataset = tf.data.Dataset.from_tensors(([1.],[1.])).repeat(4).batch(global_batch_size)
>>> dist_dataset = strategy.experimental_distribute_dataset(dataset)
>>> @tf.function
... def train_step(input):
... features, labels = input
... return labels - 0.3 * features
>>> for x in dist_dataset:
... # train_step trains the model using the dataset elements

Placing the loop inside a `tf.function` will give a performance boost.
However `break` and `return` are currently not supported if the loop is
placed inside a `tf.function`. We also don't support placing the loop
inside a `tf.function` when using
`tf.distribute.experimental.MultiWorkerMirroredStrategy` or
`tf.distribute.experimental.TPUStrategy` with multiple workers.
* use `__iter__` to create an explicit iterator, which is of type
`tf.distribute.DistributedIterator`
>>> global_batch_size = 4
>>> strategy = tf.distribute.MirroredStrategy(["GPU:0", "GPU:1"])
>>> train_dataset = tf.data.Dataset.from_tensors(([1.],[1.])).repeat(50).batch(global_batch_size)
>>> train_dist_dataset = strategy.experimental_distribute_dataset(train_dataset)
>>> @tf.function
... def distributed_train_step(dataset_inputs):
... def train_step(input):
... loss = tf.constant(0.1)
... return loss
... per_replica_losses = strategy.run(train_step, args=(dataset_inputs,))
... return strategy.reduce(tf.distribute.ReduceOp.SUM, per_replica_losses,axis=None)
>>> EPOCHS = 2
>>> STEPS = 3
>>> for epoch in range(EPOCHS):
... total_loss = 0.0
... num_batches = 0
... dist_dataset_iterator = iter(train_dist_dataset)
... for _ in range(STEPS):
... total_loss += distributed_train_step(next(dist_dataset_iterator))
... num_batches += 1
... average_train_loss = total_loss / num_batches
... template = ("Epoch {}, Loss: {:.4f}")
... print (template.format(epoch+1, average_train_loss))
Epoch 1, Loss: 0.2000
Epoch 2, Loss: 0.2000
To achieve a performance improvement, you can also wrap the `strategy.run`
call with a `tf.range` inside a `tf.function`. This runs multiple steps in a
`tf.function`. Autograph will convert it to a `tf.while_loop` on the worker.
However, it is less flexible comparing with running a single step inside
`tf.function`. For example, you cannot run things eagerly or arbitrary
python code within the steps.
2. Inspect the `tf.TypeSpec` of the data generated by `DistributedDataset`.
`tf.distribute.DistributedDataset` generates
`tf.distribute.DistributedValues` as input to the devices. If you pass the
input to a `tf.function` and would like to specify the shape and type of
each Tensor argument to the function, you can pass a `tf.TypeSpec` object to
the `input_signature` argument of the `tf.function`. To get the
`tf.TypeSpec` of the input, you can use the `element_spec` property of the
`tf.distribute.DistributedDataset` or `tf.distribute.DistributedIterator`
object.
For example:
>>> global_batch_size = 4
>>> epochs = 1
>>> steps_per_epoch = 1
>>> mirrored_strategy = tf.distribute.MirroredStrategy(["GPU:0", "GPU:1"])
>>> dataset = tf.data.Dataset.from_tensors(([2.])).repeat(100).batch(global_batch_size)
>>> dist_dataset = mirrored_strategy.experimental_distribute_dataset(dataset)
>>> @tf.function(input_signature=[dist_dataset.element_spec])
... def train_step(per_replica_inputs):
... def step_fn(inputs):
... return tf.square(inputs)
... return mirrored_strategy.run(step_fn, args=(per_replica_inputs,))
>>> for _ in range(epochs):
... iterator = iter(dist_dataset)
... for _ in range(steps_per_epoch):
... output = train_step(next(iterator))
... print(output)
