This flag is on + +Please install pre-commit, which automatically reformat the changes to C/C++ and Python code whenever we run `git commit`. To check the whole codebase, we can run the command `pre-commit run -a`, as in the [`check_style.sh` file](https://github.com/PaddlePaddle/Paddle/blob/b84e8226514b8bb4405c3c28e54aa5077193d179/paddle/scripts/travis/check_style.sh#L30), which is invoked by [our Travis CI configuration](https://github.com/PaddlePaddle/Paddle/blob/b84e8226514b8bb4405c3c28e54aa5077193d179/.travis.yml#L43). + +### Unit Tests + +Please remember to add related unit tests. + +- For C/C++ code, please follow [`google-test` Primer](https://github.com/google/googletest/blob/master/googletest/docs/Primer.md). + +- For Python code, please use [Python's standard `unittest` package](http://pythontesting.net/framework/unittest/unittest-introduction/). + + +### Writing Logs + +We use [glog](https://github.com/google/glog) for logging in our C/C++ code. + +For general information, please use `LOG`. For debug information, please use [`VLOG`](http://htmlpreview.github.io/?https://github.com/google/glog/blob/master/doc/glog.html#verbose). The reason is at [here](https://groups.google.com/a/chromium.org/d/msg/chromium-dev/3NDNd1KzXeY/AZKMMx37fdQJ). + +`VLOG` requires a *verbose level* parameter. For example: + +```c++ +VLOG(3) << "Operator FC is taking " << num_inputs << "inputs." +``` + +When we run a PaddlePaddle application or test, we can specify a verbose threshold. For example: + +```bash +GLOG_vmodule=buddy_allocator=2 \ +GLOG_v=10 \ +python \ +../python/paddle/v2/framework/tests/test_recurrent_op.py +``` + +This will enable VLOG messages generated by `buddy_allocator.{h,cc}` and in the verbose range of 0 to 3, so you will see above example VLOG message, which is in level 3. This suggests that we output overall messages in lower verbose levels, so they display with higher probability. When coding C++, please follow the verbose level convention as follows: + +- verbose level 1: [framework](https://github.com/PaddlePaddle/Paddle/tree/develop/paddle/framework) +- verbose level 3: [operators](https://github.com/PaddlePaddle/Paddle/tree/develop/paddle/operators) +- verbose level 5: [memory](https://github.com/PaddlePaddle/Paddle/tree/develop/paddle/memory),

decoder](https://github.com/PaddlePaddle/book/blob/develop/08.machine_translation/README.md) is necessary to generate sequences. + +This documentation describes how to implement the sequence decoder as an operator. + +## Beam Search based Decoder +The [beam search algorithm](https://en.wikipedia.org/wiki/Beam_search) is necessary when generating sequences, +it is a heuristic search algorithm that explores the paths by expanding the most promising node in a limited set. + +In the old version of PaddlePaddle, a C++ class `RecurrentGradientMachine` implements the general sequence decoder based on beam search, +due to the complexity, the implementation relays on a lot of special data structures, +quite trivial and hard to be customized by users. + +There are a lot of heuristic tricks in the sequence generation tasks, +so the flexibility of sequence decoder is very important to users. + +During PaddlePaddle's refactoring work, +some new concept is proposed such as [LoDTensor](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/framework/lod_tensor.md) and [TensorArray](https://github.com/PaddlePaddle/Paddle/blob/develop/doc/design/tensor_array.md) that can better support sequence usage, +and they can help to make the implementation of beam search based sequence decoder **more transparent and modular** . + +For example, the RNN sates, candidates IDs and probabilities of beam search can be represented as `LoDTensors`; +the selected candidate's IDs in each time step can be stored in a `TensorArray`, and `Packed` to the sentences translated. + +## Changing LoD's absolute offset to relative offsets +The current `LoDTensor` is designed to store levels of variable-length sequences, +it stores several arrays of integers each represents a level. + +The integers in each level represents the begin and end (not inclusive) offset of a sequence **in the underlying tensor**, +let's call this format the **absolute-offset LoD** for clear. + +The relative-offset LoD can fast retrieve any sequence but fails to represent empty sequences, for example, a two-level LoD is as follows +```python +[[0, 3, 9] + [0, 2, 3, 3, 3, 9]] +``` +The first level tells that there are two sequences: +- the first's offset is `[0, 3)` +- the second's offset is `[3, 9)` + +while on the second level, there are several empty sequences that both begin and end at `3`. +It is impossible to tell how many empty second-level sequences exist in the first-level sequences. + +There are many scenarios that relay on empty sequence representation, +such as machine translation or image to text, one instance has no translations or the empty candidate set for a prefix. + +So let's introduce another format of LoD, +it stores **the offsets of the lower level sequences** and is called **relative-offset** LoD. + +For example, to represent the same sequences of the above data + +```python +[[0, 3, 6] + [0, 2, 3, 3, 3, 9]] +``` + +the first level represents that there are two sequences, +their offsets in the second-level LoD is `[0, 3)` and `[3, 5)`. + +The second level is the same with the relative offset example because the lower level is a tensor. +It is easy to find out the second sequence in the first-level LoD has two empty sequences. + +The following demos are based on relative-offset LoD. + +## Usage in a simple machine translation model +Let's start from a simple machine translation model that is simplified from [machine translation chapter](https://github.com/PaddlePaddle/book/tree/develop/08.machine_translation) to draw a simple

article, we'll explain how to run distributed training jobs with PaddlePaddle on different types of clusters. The diagram below shows the main architecture of a distributed trainning job: + + + +- Data shard: training data will be split into multiple partitions, trainers use the partitions of the whole dataset to do the training job. +- Trainer: each trainer reads the data shard, and train the neural network. Then the trainer will upload calculated "gradients" to parameter servers, and wait for parameters to be optimized on the parameter server side. When that finishes, the trainer download optimized parameters and continues its training. +- Parameter server: every parameter server stores part of the whole neural network model data. They will do optimization calculations when gradients are uploaded from trainers, and then send updated parameters to trainers. + +PaddlePaddle can support both synchronize stochastic gradient descent (SGD) and asynchronous SGD. + +When training with synchronize SGD, PaddlePaddle uses an internal "synchronize barrier" which makes gradients update and parameter download in strict order. On the other hand, asynchronous SGD won't wait for all trainers to finish upload at a single step, this will increase the parallelism of distributed training: parameter servers do not depend on each other, they'll do parameter optimization concurrently. Parameter servers will not wait for trainers, so trainers will also do their work concurrently. But asynchronous SGD will introduce more randomness and noises in the gradient. + +## Preparations +1. Prepare your computer cluster. It's normally a bunch of Linux servers connected by LAN. Each server will be assigned a unique IP address. The computers in the cluster can be called "nodes". +2. Install PaddlePaddle on every node. If you are going to take advantage of GPU cards, you'll also need to install proper driver and CUDA libraries. To install PaddlePaddle please read [this build and install](https://github.com/PaddlePaddle/Paddle/tree/develop/doc/getstarted/build_and_install) document. We strongly recommend using [Docker installation](https://github.com/PaddlePaddle/Paddle/blob/develop/doc/getstarted/build_and_install/docker_install_en.rst). + +After installation, you can check the version by typing the below command (run a docker container if using docker: `docker run -it paddlepaddle/paddle:[tag] /bin/bash`): + +```bash +$ paddle version +PaddlePaddle 0.10.0rc, compiled with + with_avx: ON + with_gpu: OFF + with_double: OFF + with_python: ON + with_rdma: OFF + with_timer: OFF +``` -In this article, we explain how to run distributed Paddle training jobs on clusters. We will create the distributed version of the single-process training example, [recommendation](https://github.com/baidu/Paddle/tree/develop/demo/recommendation). +We'll take `doc/howto/usage/cluster/src/word2vec` as an example to introduce distributed training using PaddlePaddle v2 API. -[Scripts](https://github.com/baidu/Paddle/tree/develop/paddle/scripts/cluster_train) used in this article launch distributed jobs via SSH. They also work as a reference for users running more sophisticated cluster management systems like MPI and [Kubernetes](https://github.com/PaddlePaddle/Paddle/tree/develop/doc/howto/usage/k8s). +## Command-line arguments -## Prerequisite +### Starting parameter server -1. Aforementioned scripts use a Python library [fabric](http://www.fabfile.org/) to run SSH commands. We can use `pip` to install fabric: +Type the below command to start a parameter server which will wait for trainers to connect: - ```bash - pip install fabric - ``` +```bash +$ paddle pserver --port=7164 --ports_num=1 --ports_num_for_sparse=1 --num_gradient_servers=1 +``` -1. We need to install PaddlePaddle on all nodes in the cluster. To enable GPUs, we need to install CUDA in `/usr/local/cuda`; otherwise Paddle would report errors at runtime. +If you wish to run parameter servers in background, and save a log file, you can type: +```bash +$ stdbuf -oL /usr/bin/nohup paddle pserver --port=7164 --ports_num=1 --ports_num_for_sparse=1 --num_gradient_servers=1 &> pserver.log +``` -1. Set the `ROOT_DIR` variable in [`cluster_train/conf.py`] on all nodes. For convenience, we often create a Unix user `paddle` on all nodes and set `ROOT_DIR=/home/paddle`. In this way, we can write public SSH keys into `/home/paddle/.ssh/authorized_keys` so that user `paddle` can SSH to all nodes without password. +| param | required | default | description | +| ------------- | ------------- | ------------- | ------------- | +| port | required | 7164 | port which parameter server will listen on. If ports_num greater than 1, parameter server will listen on multiple ports for more network throughput | +| ports_num | required | 1 | total number of ports will listen on | +| ports_num_for_sparse | required | 1 | number of ports which serves sparse parameter update | +| num_gradient_servers | required | 1 | total number of gradient servers | -## Prepare Job Workspace +### Starting trainer +Type the command below to start the trainer(name the file whatever you want, like "train.py") -We refer to the directory where we put dependent libraries, config files, etc., as *workspace*. +```bash +$ python train.py +``` -These `train/test` data should be prepared before launching cluster job. To satisfy the requirement that train/test data are placed in different directory from workspace, PADDLE refers train/test data according to index file named as `train.list/test.list` which are used in model config file. So the train/test data also contains train.list/test.list two list file. All local training demo already provides scripts to help you create these two files, and all nodes in cluster job will handle files with same logical code in normal condition. +Trainers' network need to be connected with parameter servers' network to finish the job. Trainers need to know port and IPs to locate parameter servers. You can pass arguments to trainers through [environment variables](https://en.wikipedia.org/wiki/Environment_variable) or pass to `paddle.init()` function. Arguments passed to the `paddle.init()` function will overwrite environment variables. -Generally, you can use same model file from local training for cluster training. What you should have in mind that, the `batch_size` set in `setting` function in model file means batch size in `each` node of cluster job instead of total batch size if synchronization SGD was used. +Use environment viriables: -Following steps are based on [demo/recommendation](https://github.com/PaddlePaddle/Paddle/tree/develop/demo/recommendation) demo in demo directory. +```bash +export PADDLE_INIT_USE_GPU=False +export PADDLE_INIT_TRAINER_COUNT=1 +export PADDLE_INIT_PORT=7164 +export PADDLE_INIT_PORTS_NUM=1 +export PADDLE_INIT_PORTS_NUM_FOR_SPARSE=1 +export PADDLE_INIT_NUM_GRADIENT_SERVERS=1 +export PADDLE_INIT_TRAINER_ID=0 +export PADDLE_INIT_PSERVERS=127.0.0.1 +python train.py +``` -You just go through demo/recommendation tutorial doc until `Train` section, and at last you will get train/test data and model configuration file.

It adjusts the mean and variance of a layer's output, and make the data distribution easier for next layer's training. + +The principle of batch normalization can be summarized into a simple function: + +``` +y = (x - E[x]) / STD[x]) * scale + bias +``` + +`x` is a batch of output data of a certain layer. `E[x]` and `STD[x]` is the mean and standard deviation of `x`, respectively。 `scale` and `bias` are two trainable parameters. The training of batch normalization layer equals to the learning of best values of `scale` and `bias`. + +In our design, we use a single operator(`batch_norm_op`) to implement the whole batch normalization in C++, and wrap it as a layer in Python. + +## Differences with normal operators + +`batch_norm_op` is a single operator. However, there are a few differences between `BatchNormOp` and normal operators, which we shall take into consideration in our design. + +1. `batch_norm_op` shall behave differently in training and inferencing. For example, during inferencing, there is no batch data and it's impossible to compute `E[x]` and `STD[x]`, so we have to use an `estimated_mean` and an `estimated_variance` instead of them. These require our framework to be able to inform operators current running type (training/inferencing), then operators can switch their behaviors. + +2. `batch_norm_op` shall have the ability to maintain `estimated_mean` and `estimated_variance` across mini-batch. In each mini-batch, `estimated_mean` is iterated by the following equations: + +``` +if batch_id == 0 + estimated_mean = E[x] +else + estimated_mean = estimated_mean * momentum + (1.0 - momentum_) * E[x] +``` + +The iterating of `estimated_variance` is similar. `momentum` is an attribute, which controls estimated_mean updating speed. + +## Implementation + +Batch normalization is designed as a single operator is C++, and then wrapped as a layer in Python. + +### C++ + +As most C++ operators do, `batch_norm_op` is defined by inputs, outputs, attributes and compute kernels. + +#### Inputs + +- `x`: The inputs data, which is generated by the previous layer. +- `estimated_mean`: The estimated mean of all previous data batches. It is updated in each forward propagation and will be used in inferencing to take the role of `E[x]`. +- `estimated_var`: The estimated standard deviation of all previous data batches. It is updated in each forward propagation and will be used in inferencing to take the role of `STD[x]`. +- `scale`: trainable parameter 'scale' +- `bias`: trainable parameter 'bias' + +#### Outputs + +- `y`: The output data. +- `batch_mean`: The mean value of batch data. +- `batch_var`: The standard deviation value of batch data. +- `saved_mean`: Updated `estimated_mean` with current batch data. It's supposed to share the memory with input `estimated_mean`. +- `saved_var`: Updated `estimated_var` with current batch data. It's supposed to share the memory with input `estimated_var`. + +#### Attributes + +- `is_infer`: *bool*. If true, run `batch_norm_op` in inferencing mode. +- `use_global_est`: *bool*. If true, use `saved_mean` and `saved_var` instead of `E[x]` and `STD[x]` in trainning. +- `epsilon`: *float*. The epsilon value to avoid division by zero. +- `momentum`: *float*. Factor used in `estimated_mean` and `estimated_var` updating. The usage is shown above. + +#### Kernels + +The following graph showes the training computational process of `batch_norm_op`: + + + +cudnn provides APIs to finish the whole series of computation, we can use them in our GPU kernel. + +### Python + +`batch_norm_op` is warpped as a layer in Python: + +```python +def batch_norm_layer(net, + input, + output, + scale, + bias, + use_global_est = False, + epsilon = 1e-6, + momentum = 0.99): + mean_cache = scope.new_var(name = 'estimated_mean', trainable = False) + var_cache = scop.new_var(name = 'estimated_var', trainable = False) + batch_mean = scope.new_var(name = 'batch_mean') + batch_var = scope.new_var(name = 'batch_var') + batch_norm_op = Operator('batch_norm_op', + x = input, + estimated_mean = mean_cache, + estimated_mean = var_cache, + scale = scale, + bias = bias, + y = output, + batch_mean = batch_mean, + batch_var = batch_var, + saved_mean = mean_cache, + saved_var = var_cache, + is_infer = False, + use_global_est = use_global_est, + epsilon = epsilon, + momentum = momentum) + net.append_op(batch_norm_op) + return output +``` + +Because Python API has not been finally decided, the code above can be regarded as pseudo code. There are a few key points we shall note: + +1. `estimated_mean` and `estimated_var` are assigned the same variables with `saved_mean` and `saved_var` respectively. So they share same the memories. The output mean and variance values(`saved_mean` and `saved_var`) of a certain batch will be the inputs(`estimated_mean` and `estimated_var`) of the next batch. + +2. `is_infer` decided whether `batch_norm_op` will run in training mode or inferencing mode. However, a network may contains both training and inferencing parts. And user may switch `batch_norm_op`'s running mode in Python `for` loop like this: + +```python +for pass_id in range(PASS_NUM): + # ... + net.train() # run training model + if pass_id % 100 == 0: + net.infer(test_image) # run inferencing model + # ... +``` + +`is_infer` is an attribute. Once an operator is created, its attributes can not be changed. It suggests us that we shall maintain two `batch_norm_op` in the model, one's `is_infer` is `True`(we call it `infer_batch_norm_op`) and the other one's is `False`(we call it `train_batch_norm_op`). They share all parameters and variables, but be placed in two different branches. That is to say, if a network contains a `batch_norm_op`, it will fork into two branches, one go through `train_batch_norm_op` and the other one go through `infer_batch_norm_op`: + +
+ +
+ +Just like what is shown in the above graph, the net forks before `batch_norm_op` and will never merge again. All the operators after `batch_norm_op` will duplicate. + +When the net runs in training mode, the end of the left branch will be set as the running target, so the dependency tracking process will ignore right branch automatically. When the net runs in inferencing mode, the process is reversed. + +How to set a target is related to Python API design, so I will leave it here waiting for more discussions. diff --git a/paddle/operators/cast_op.cc b/paddle/operators/cast_op.cc new file mode 100644 index 0000000000000000000000000000000000000000..70ee7861bab3a982eae60dd85b10c2e41f5827d0 --- /dev/null +++ b/paddle/operators/cast_op.cc @@ -0,0 +1,77 @@ +/* Copyright (c) 2016 PaddlePaddle Authors.

The key point +is that the listed equations are satisfied by ids. + + tag_type = label % num_tag_type + chunk_type = label / num_tag_type + +where `num_tag_type` is the num of tag types in the tagging scheme, `num_chunk_type` +is the num of chunk types, and `tag_type` get its value from the following table. + + Scheme Begin Inside End Single + plain 0 - - - + IOB 0 1 - - + IOE - 0 1 - + IOBES 0 1 2 3 + +Still use NER as example, assuming the tagging scheme is IOB while chunk types are ORG, +PER and LOC. To satisfy the above equations, the label map can be like this: + + B-ORG 0 + I-ORG 1 + B-PER 2 + I-PER 3 + B-LOC 4 + I-LOC 5 + O 6 + +It’s not hard to verify the equations noting that the num of chunk types +is 3 and the num of tag types in IOB scheme is 2.
