在Ascend昇腾硬件用npu加速paddleLite版本ocr（nnadapter）

参考文档
- * nnadapter参考文档地址
- * 华为昇腾 NPU参考文档地址
- * PaddleLite的C++API参考文档
一.确保cpu版本运行正常
二.编译Ascend上npu加速库
三.跑通npu加速版本Demo
- 1.Demo下载地址
- 2.参考手册网址
- 3.改脚本run.sh
- - （1）.改参数HUAWEI_ASCEND_TOOLKIT_HOME
  - （2）.改参数NNADAPTER_DEVICE_NAMES，NNADAPTER_MODEL_CACHE_DIR，NNADAPTER_MODEL_CACHE_TOKEN
- 4.完整log日志
- - 不包含转nnc模型的日志
  - 包含转nnc模型的日志
四.将ocr代码改成nnadapter与ascendnpu格式
五.必须设置环境变量！
- 1.写入环境变量
- 2.脚本里写进临时环境变量
五.部分模型不能成功转成nnc格式加速的问题
六.考虑其他办法

* 华为昇腾 NPU参考文档地址

https://www.paddlepaddle.org.cn/lite/develop/demo_guides/huawei_ascend_npu.html#npu

* PaddleLite的C++API参考文档

一.确保cpu版本运行正常

参考我之前的教程
http://t.csdnimg.cn/Nd4Qv

二.编译Ascend上npu加速库

之前的教程有提到过编译ascend_npu加速库失败，后来发现是paddleLite与ascend-toolkit版本不兼容的问题，所以导致未知原因的编译失败，这次用到的是2.10版本的paddleLite与5.0.2.alpha003的toolkit最后编译成功

三.跑通npu加速版本Demo

1.Demo下载地址

https://paddlelite-demo.bj.bcebos.com/devices/generic/PaddleLite-generic-demo.tar.gz

2.参考手册网址

https://www.paddlepaddle.org.cn/lite/develop/demo_guides/huawei_ascend_npu.html#npu-paddle-lite

3.改脚本run.sh

（1）.改参数HUAWEI_ASCEND_TOOLKIT_HOME

注意将HUAWEI_ASCEND_TOOLKIT_HOME这个参数的地址改成自己的昇腾toolkit地址，不然不能调用npu加速

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.:../../libs/PaddleLite/$TARGET_OS/$TARGET_ABI/lib:../../libs/PaddleLite/$TARGET_OS/$TARGET_ABI/lib/$NNADAPTER_DEVICE_NAMES:../../libs/PaddleLite/$TARGET_OS/$TARGET_ABI/lib/cpu
if [ "$NNADAPTER_DEVICE_NAMES" == "huawei_ascend_npu" ]; then
    HUAWEI_ASCEND_TOOLKIT_HOME="/home/HwHiAiUser/Ascend/ascend-toolkit/5.0.2.alpha003" #"/usr/local/Ascend/ascend-toolkit/6.0.RC1.alpha003"
    if [ "$TARGET_OS" == "linux" ]; then
      if [[ "$TARGET_ABI" != "arm64" && "$TARGET_ABI" != "amd64" ]]; then
        echo "Unknown OS $TARGET_OS, only supports 'arm64' or 'amd64' for Huawei Ascend NPU."
        exit -1
      fi
    else
      echo "Unknown OS $TARGET_OS, only supports 'linux' for Huawei Ascend NPU."
      exit -1
    fi
    NNADAPTER_CONTEXT_PROPERTIES="HUAWEI_ASCEND_NPU_SELECTED_DEVICE_IDS=0"
    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64:$HUAWEI_ASCEND_TOOLKIT_HOME/fwkacllib/lib64:$HUAWEI_ASCEND_TOOLKIT_HOME/acllib/lib64:$HUAWEI_ASCEND_TOOLKIT_HOME/atc/lib64:$HUAWEI_ASCEND_TOOLKIT_HOME/opp/op_proto/built-in
    export PYTHONPATH=$PYTHONPATH:$HUAWEI_ASCEND_TOOLKIT_HOME/fwkacllib/python/site-packages:$HUAWEI_ASCEND_TOOLKIT_HOME/acllib/python/site-packages:$HUAWEI_ASCEND_TOOLKIT_HOME/toolkit/python/site-packages:$HUAWEI_ASCEND_TOOLKIT_HOME/atc/python/site-packages:$HUAWEI_ASCEND_TOOLKIT_HOME/pyACL/python/site-packages/acl
    export PATH=$PATH:$HUAWEI_ASCEND_TOOLKIT_HOME/atc/ccec_compiler/bin:${HUAWEI_ASCEND_TOOLKIT_HOME}/acllib/bin:$HUAWEI_ASCEND_TOOLKIT_HOME/atc/bin
    export ASCEND_AICPU_PATH=$HUAWEI_ASCEND_TOOLKIT_HOME
    export ASCEND_OPP_PATH=$HUAWEI_ASCEND_TOOLKIT_HOME/opp
    export TOOLCHAIN_HOME=$HUAWEI_ASCEND_TOOLKIT_HOME/toolkit
    export ASCEND_SLOG_PRINT_TO_STDOUT=1
    export ASCEND_GLOBAL_LOG_LEVEL=1
fi

（2）.改参数NNADAPTER_DEVICE_NAMES，NNADAPTER_MODEL_CACHE_DIR，NNADAPTER_MODEL_CACHE_TOKEN

NNADAPTER_DEVICE_NAMES="huawei_ascend_npu"

NNADAPTER_MODEL_CACHE_DIR是装nnc模型的文件夹，最开始没有生成nnc模型的时候就只用写指定生成模型地址，
NNADAPTER_MODEL_CACHE_TOKEN=“null”,在保存nnc模型后，将NNADAPTER_MODEL_CACHE_TOKEN参数写为生成后的模型名字

4.完整log日志

发现调用npu是用了这样一个过程，先将nb格式的模型转成，nnc格式，然后再npu调用这个nnc格式模型进行加速推理，如果已经转过nnc格式保存在相应文件夹，就会直接调用这个nnc模型，省略了这个转模型的步骤，直接进行推理

不包含转nnc模型的日志

包含转nnc模型的日志

四.将ocr代码改成nnadapter与ascendnpu格式

通过研究demo发现，，paddleLite调用ascend加速npu的代码最重要的是在添加nnadapter_device参数，在昇腾上就应该设置为huawei_ascend_npu

下面的红框部分是我依据Demo改写的，但是会报不知名错误

暂不知道具体因为什么原因

五.必须设置环境变量！

必须将ascend相关环境写进环境变量，且不可再调用可执行文件的脚本里重复export环境变量，不然还会出现奇奇怪怪的错误

1.写入环境变量

vim ~/.bashrc

参考自己环境里的相关ascend-toolkit装在什么地址来改写

五.部分模型不能成功转成nnc格式加速的问题

然后我想到了一个新方法，直接用能成功调用npu加速的Demo来直接将这些ocr模型转换成加密nnc格式

ascend文档
https://www.paddlepaddle.org.cn/lite/develop/demo_guides/huawei_ascend_npu.html#npu

然后发现在文档种写的支持的上列模型，det模型能成功转换，而rec模型并不能成功转换



上面三张截图是ch-ppocr-mobile v2.O_rec，0 ch ppocr_server v2 .0rec，0 ch PP-OCRv2 rec的转换结果，可以看到都转换失败。

det模型转换成功

说明抛开其他因素，一些模型本身也是无法转换的

六.考虑其他办法
