+# Python api netrans_py 使用介绍
+
+netrans_py 支持通过 python api 灵活地将模型转换成pnna 支持的格式。
+使用 ntrans_py 完成模型转换的步骤如下：
+1. 导入模型
+2. 生成并修改前处理配置文件 *_inputmeta.yml
+3. 量化模型
+4. 导出模型
+
+## 安装
+在使用netrans_py之前，需要安装netrans_py。
+
+设置环境变量 NETRANS_PATH 并指向该 bin 目录。
+<font color="#dd0000">注意：</font> 在该项目中，项目下载目录为  `/home/nudt_dps/netrans`，在您应用的过程中，可以使用 `pwd` 来确认您的项目目录。
+
+```bash
+export NETRANS_PATH=/home/nudt_dps/netrans/bin
+```
+同时设置LD_LIBRARY_PATH(Ubuntu，其他系统根据具体情况设置)：
+
+```bash
+export LD_LIBRARY_PATH=/home/nudt_dps/netrans/bin:$LD_LIBRARY_PATH
+```
+注意这一步每次使用前都需要执行，或者您可以写入 .bashrc (路径为 `~/.bashrc` )。
+
+然后进入目录 netrans_py 进行安装。
+```bash
+cd /home/nudt_dps/netrans/netrans_py
+pip3 install -e .
+```
+## netrans_py api
+### Netrans 导入api及创建实例
+创建 Netrans
+
+ 描述： 实例化 Netrans 类。
+ 代码示例：
+
+ ```py3
+ from netrans import Netrans
+ yolo_netrans = Netrans("../examples/darknet/yolov4_tiny")
+ ```
+
+ 参数
+ 
+| 参数名 | 类型 | 说明  |
+|:---| -- | -- |
+|model_path| str| 第一位置参数，模型文件的路径|
+|netans| str | 如果 NETRANS_PATH 没有设置，可通过该参数指定netrans的路径|
+
+输出返回：
+无。
+
+<font color="#dd0000">注意：</font> 模型目录准备需要和netrans_cli一致，具体数据准备要求见[introduction](./introduction.md)。
+
+### Netrans.load_model 模型导入 
+
+ 描述： 将模型转换成 pnna 支持的格式。
+ 代码示例：
+
+ ```py3
+ yolo_netrans.load_model()
+ ```
+
+ 参数：
+    无。
+
+ 输出返回：
+    无。
+    在工程目录下生成 pnna 支持的模型格式，以.json结尾的模型文件和 .data结尾的权重文件。
+
+### Netrans.gen_inputmeta 预处理配置文件生成 
+
+ 描述： 将模型转换成 pnna 支持的格式。
+ 代码示例：
+
+ ```py3
+ yolo_netrans.gen_inputmeta()
+ ```
+
+ 参数：
+    无。
+
+ 输出返回：
+    无。
+
+### Netrans.quantize 量化模型 
+
+ 描述： 对模型生成量化配置文件。
+ 代码示例：
+
+ ```py3
+ yolo_netrans.quantize("uint8")
+ ```
+
+ 参数：
+ 
+| 参数名 | 类型 | 说明  |
+|:---| -- | -- |
+|quantize_type| str| 第一位置参数，模型量化类型，仅支持 "uint8", "int8", "int16"|
+
+ 输出返回：
+    无。
+
+### Netrans.export 模型导出
+
+ 描述： 对模型生成量化配置文件。
+ 代码示例：
+
+ ```py3
+ yolo_netrans.export()
+ ```
+
+ 参数：
+    无。
+
+ 输出返回：
+    无。请在目录 “wksp/*/” 下检查是否生成nbg文件。
+
+### Netrans.model2nbg 一键生成nbg文件
+
+ 描述： 模型导入、量化、及nbg文件生产
+ 代码示例：
+
+ ```py3 
+ # 无预处理
+yolo_netrans.model2nbg(quantize_type='uint8')
+ # 需要对数据进行normlize, menas为128, scale 为 0.0039
+yolo_netrans.model2nbg(quantize_type='uint8',mean=128, scale = 0.0039)
+ # 需要对数据分通道进行normlize, menas为128,127,125,scale 为 0.0039, 且reverse_channel 为 True 
+yolo_netrans.model2nbg(quantize_type='uint8'mean=[128, 127, 125], scale = 0.0039, reverse_channel= True)
+ # 已经进行初始化设置
+yolo_netrans.model2nbg(quantize_type='uint8', inputmeta=True)
+
+ ```
+
+ 参数
+| 参数名 | 类型 | 说明  |
+|:---| -- | -- |
+|quantize_type| str, ["uint8", "int8", "int16" ] | 量化类型，将模型量化成该参数指定的类型 |
+|inputmeta| bool,str, [Fasle, True, "inputmeta_filepath"] | 指定 inputmeta, 默认为False。 <br/> 如果为False，则会生成inputmeta模板，可使用mean、scale、reverse_channel 配合修改常用参数。<br/>如果已有现成的 inputmeta 文件，则可通过该参数进行指定，也可使用True, 则会自动索引 model_name_inputmeta.yml |
+|mean| float, int, list | 设置预处理中 normalize 的 mean 参数 |
+|scale| float, int, list | 设置预处理中 normalize 的 scale 参数 |
+|reverse_channel | bool | 设置预处理中的 reverse_channel 参数 |
+<!-- |||| -->
+
+输出返回：
+请在目录 “wksp/*/” 下检查是否生成nbg文件。
+
+## 使用实例
+
+ ```
+from nertans import Netrans
+model_path = 'example/darknet/yolov4_tiny'
+netrans_path = "netrans/bin" # 如果进行了export定义申明，这一步可以不用
+
+# 初始化netrans
+net = Netrans(model_path,netrans=netrans_path)
+# 模型载入
+net.load_model()
+# 生成 inputmeta 文件
+net.gen_inputmeta()
+# 配置预处理 normlize 的参数
+net.config(scale=1,mean=0)
+# 模型量化
+net.quantize("uint8")
+# 模型导出
+net.export()
+
+# 模型直接量化成 int16 并导出, 直接复用刚配置好的 inputmeta
+net.model2nbg(quantize_type = "int16", inputmeta=True)
+```
