 2. **我可以在服务器或云平台上部署PaddleX么？**
 
    PaddleX GUI是一个适配本地单机安装的客户端，无法在服务器上直接进行部署，您可以直接使用PaddleX API，或采用飞桨核心框架进行服务器上的部署。如果您希望使用公有算力，强烈建议您尝试飞桨产品系列中的 [EasyDL](https://ai.baidu.com/easydl/) 或 [AI Studio](https://aistudio.baidu.com/aistudio/index)进行开发。

    模型裁剪分析过程是对模型各卷积层的敏感度信息进行分析，根据各参数对模型效果的影响进行不同比例的裁剪。此过程需要重复多次直至FLOPS满足要求，最后再进行精调训练获得最终裁剪后的模型，因此耗时较长。有关模型裁剪的原理，可参见文档[剪裁原理介绍](https://paddlepaddle.github.io/PaddleSlim/algo/algo.html#2-%E5%8D%B7%E7%A7%AF%E6%A0%B8%E5%89%AA%E8%A3%81%E5%8E%9F%E7%90%86)

 需要注意的是，在本方案中，密钥集成在上层预测服务的代码中。故模型的安全强度等同于代码抵御逆向调试的强度。为了保护密钥和模型的安全，开发者还需对自己的应用进行加固保护。常见的应用加固手段有：代码混淆，二进制文件加壳 等等，亦或将加密机制更改为AES白盒加密技术来保护密钥。这类技术领域内有大量商业和开源产品可供选择，此处不一一赘述。

+可通过更换`--model_type`变量与对应的`--pretrain_weights`使用不同的模型快速尝试。
+
+## 评估
+使用下述命令进行评估
+```bash
+python eval.py --model_dir output/best_model \
+--data_dir data/mini_supervisely \
+--val_list data/mini_supervisely/val.txt \
+--image_shape 192 192
+```
+其中参数含义如下：
+* `--model_dir`: 模型路径
+* `--data_dir`: 数据集路径
+* `--val_list`: 验证集列表路径
+* `--image_shape`: 网络输入图像大小（w, h）
+
+## 预测
+使用下述命令进行预测， 预测结果默认保存在`./output/result/`文件夹中。
+```bash
+python infer.py --model_dir output/best_model \
+--data_dir data/mini_supervisely \
+--test_list data/mini_supervisely/test.txt \
+--save_dir output/result \
+--image_shape 192 192
+```
+其中参数含义如下：
+* `--model_dir`: 模型路径
+* `--data_dir`: 数据集路径
+* `--test_list`: 测试集列表路径
+* `--image_shape`: 网络输入图像大小（w, h）
+
+## 模型导出
+```bash
+paddlex --export_inference --model_dir output/best_model \
+--save_dir output/export
+```
+其中参数含义如下：
+* `--model_dir`: 模型路径
+* `--save_dir`: 导出模型保存路径
+
+## 离线量化
+```bash
+python quant_offline.py --model_dir output/best_model \
+--data_dir data/mini_supervisely \
+--quant_list data/mini_supervisely/val.txt \
+--save_dir output/quant_offline \
+--image_shape 192 192
+```
+其中参数含义如下：
+* `--model_dir`: 待量化模型路径
+* `--data_dir`: 数据集路径
+* `--quant_list`: 量化数据集列表路径，一般直接选择训练集或验证集
+* `--save_dir`: 量化模型保存路径
+* `--image_shape`: 网络输入图像大小（w, h）
