otherwise, or (ii) ownership of fifty percent (50%) or more of the
outstanding shares, or (iii) beneficial ownership of such entity.
"You" (or "Your") shall mean an individual or Legal Entity
exercising permissions granted by this License.
"Source" form shall mean the preferred form for making modifications,
including but not limited to software source code, documentation
source, and configuration files.
"Object" form shall mean any form resulting from mechanical
transformation or translation of a Source form, including but
not limited to compiled object code, generated documentation,
and conversions to other media types.
"Work" shall mean the work of authorship, whether in Source or
Object form, made available under the License, as indicated by a
copyright notice that is included in or attached to the work
(an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the
editorial revisions, annotations, elaborations, or other modifications
represent, as a whole, an original work of authorship. For the purposes
of this License, Derivative Works shall not include works that remain
separable from, or merely link (or bind by name) to the interfaces of,
the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of

(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained

pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

## 开发文档
更多详细使用方法请见[NiuTensor开发文档](http://niutrans.com/openSource/niutensor/index.html)，包括：
* 张量计算的调用接口及说明
* 示例程序（如语言模型、机器翻译等）
## 安装方法
在开始创建您的项目并使用NiuTrans.Tensor工具包时，需要注意的是：
在开始创建您的项目并使用NiuTensor工具包时，需要注意的是：
* 所创建项目如在CPU上运行，我们的系统支持高性能的数学运算库，推荐安装[MKL](https://software.intel.com/en-us/mkl)或[OpenBLAS](http://www.openblas.net/)。
* 所创建项目如需在GPU上运行，需安装 [CUDA](https://developer.nvidia.com/cuda-downloads)，CUDA版本需求为9.0及以上，CUDA工具为创建高性能GPU加速应用程序提供了开发环境。
小牛开源项目所开发的NiuTrans.Tensor工具包采用源程序编译方法，在Windows和Linux环境下的安装方法如下所示。

### Windows
若在Windows上使用NiuTrans.Tensor工具包：
若在Windows上使用NiuTensor工具包：
* 首先需要将NiuTrans.Tensor代码包含在所创建的项目中
* 首先需要将NiuTensor代码包含在所创建的项目中
* 在所创建项目中需要引用XTensor.h、core里的CHeader.h和function里的FHeader.h这三个头文件：
* 通过XTensor.h可以获取我们需要操作的XTensor类
* 通过core里的CHeader.h可以对Tensor进行一些张量运算
* 通过function里的FHeader.h可以调用一些激活函数
* 在所创建项目中使用命名空间nts
此外，一些必须的环境配置方法请参考 [NiuTrans.Tensor环境配置](http://47.105.50.196/NiuTrans/NiuTrans.Tensor/blob/master/doc/Configuration.md)。
此外，一些必须的环境配置方法请参考 [NiuTensor环境配置](https://github.com/NiuTrans/NiuTensor/blob/master/doc/Configuration.md)。
### Linux
若在Linux上使用NiuTrans.Tensor工具包，直接执行make.sh即可在同级目录下生成tensorCPU和tensorGPU，分别对应于NiuTrans.Tensor的CPU以及GPU的可执行文件。以前馈神经网络语言模型为例，输入以下命令即可在GPU上执行提供的测试用例：
>./tensorGPU -test
若在Linux上使用NiuTensor工具包，直接执行make即可在bin目录下生成NiuTensor.CPU或NiuTensor.GPU，分别对应于NiuTensor的CPU以及GPU的可执行文件，同时在lib目录下生成相应的动态链接库。以测试为例，输入以下命令即可在GPU上执行提供的测试用例：
>./bin/NiuTensor.GPU -test
更多详细使用方法请见[NiuTrans.Tensor开发文档](http://47.104.97.237/niutrans/site/niutensor/index.html)
注意：若先生成CPU的可执行文件，之后如需生成GPU可执行文件，需要先执行make clean命令，删除生成CPU时产生的中间结果
