Ubuntu部署PaddlePaddle
===================================
PaddlePaddle提供了ubuntu 14.04 deb安装包。
安装
------
安装包的下载地址是\: https://github.com/PaddlePaddle/Paddle/releases
它包含四个版本\:
* cpu版本: 支持主流x86处理器平台, 使用了avx指令集。
* cpu-noavx版本:支持主流x86处理器平台,没有使用avx指令集。
* gpu版本:支持主流x86处理器平台,支持nvidia cuda平台,使用了avx指令集。
* gpu-noavx版本:支持主流x86处理器平台,支持nvidia cuda平台,没有使用avx指令集。
下载完相关安装包后,执行:
.. code-block:: shell
sudo apt-get install gdebi
gdebi paddle-*-cpu.deb
或者:
.. code-block:: shell
dpkg -i paddle-*-cpu.deb
apt-get install -f
在 :code:`dpkg -i` 的时候如果报一些依赖未找到的错误是正常的,
在 :code:`apt-get install -f` 里会继续安装 PaddlePaddle。
安装完成后,可以使用命令 :code:`paddle version` 查看安装后的paddle 版本:
.. code-block:: shell
PaddlePaddle 0.8.0b1, compiled with
with_avx: ON
with_gpu: OFF
with_double: OFF
with_python: ON
with_rdma: OFF
with_timer: OFF
with_predict_sdk:
可能遇到的问题
--------------
libcudart.so/libcudnn.so找不到
++++++++++++++++++++++++++++++
安装完成后,运行 :code:`paddle train` 报错\:
.. code-block:: shell
0831 12:36:04.151525 1085 hl_dso_loader.cc:70] Check failed: nullptr != *dso_handle For Gpu version of PaddlePaddle, it couldn't find CUDA library: libcudart.so Please make sure you already specify its path.Note: for training data on Cpu using Gpu version of PaddlePaddle,you must specify libcudart.so via LD_LIBRARY_PATH.
原因是未设置cuda运行时环境变量。 如果使用GPU版本的PaddlePaddle,请安装CUDA 7.5 和CUDNN 5到本地环境中,并设置:
.. code-block:: shell
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:/usr/local/cuda/lib:$LD_LIBRARY_PATH
export PATH=/usr/local/cuda/bin:$PATH
Debian Package installation guide
=================================
PaddlePaddle supports :code:`deb` pacakge. The installation of this :code:`deb` package is tested in ubuntu 14.04, but it should be support other debian based linux, too.
There are four versions of debian package, :code:`cpu`, :code:`gpu`, :code:`cpu-noavx`, :code:`gpu-noavx`. And :code:`noavx` version is used to support CPU which does not contain :code:`AVX` instructions. The download url of :code:`deb` package is \: https://github.com/baidu/Paddle/releases/
After downloading PaddlePaddle deb packages, you can use :code:`gdebi` install.
.. code-block:: bash
gdebi paddle-*.deb
If :code:`gdebi` is not installed, you can use :code:`sudo apt-get install gdebi` to install it.
Or you can use following commands to install PaddlePaddle.
.. code-block:: bash
dpkg -i paddle-*.deb
apt-get install -f
And if you use GPU version deb package, you need to install CUDA toolkit and cuDNN, and set related environment variables(such as LD_LIBRARY_PATH) first. It is normal when `dpkg -i` get errors. `apt-get install -f` will continue install paddle, and install dependences.

This layer is used in learning to search models, which is to solve complex
joint prediction problems based on learning to search through a
problem-defined search space.
Specifically, the learning to search process for this layer begins with
searching a target sequence from a nested sequence. In the first search
step, top beam size sequences with highest scores, indices of these top k
sequences in the original nested sequence, and the ground truth (also
called gold) altogether (a triple) make up of the first beam.
Then, several special positions, for example, start and end positions
that define meaningful segments are searched. In these searches, top k
positions with highest scores are selected, and then sequence, starting
from the selected starts till ends of the sequences (or a fixed position)
are taken to search next.
We call the possible top k results returned in one search the beam. This
search process can be repeated for pre-defined turns and leads to several
beam expansions.
Finally, the layer cross_entropy_over_beam takes all the beam expansions
which contain several candidate targets found along the multi-step search.
cross_entropy_over_beam calculates cross entropy over the expanded beams
which all the candidates in the beam as the normalized factor.
Note that, if gold falls off the beam at search step t, then the cost is
calculated over the beam at step t.
This cost layer always works together with kmax_sequence_score_layer,
sub_nested_seq_layer, and sequence_slice_layer to trim the input to form a
sub-search space.
The example usage is:
.. code-block:: python
cost = cross_entropy_over_beam(input=[
BeamInput(
candidate_scores=beam1_candidates,
selected_candidates=beam1_topk,
gold=gold1),
BeamInput(
