您好，请拉这个PR测试：https://github.com/PaddlePaddle/Paddle2ONNX/pull/399

yeliang2258 commented 2 years ago

另外，用户您好，请问你转换为ONNX模型的目的是？用于部署的话，请问部署引擎是？

Hi, @zhangxianjie1314

我们准备了一份简单的问题调研（半分钟可完成），如有时间可帮忙完成调研，帮助Paddle2ONNX做得更好 https://iwenjuan.baidu.com/?code=r8hu2s

想用onnx来进行部署，但是用tensorrt对量化后的onnx进行部署时，发现onnx2trt似乎不支持int8的onnx，所以想请教一下，如果对int8模型进行部署，有什么推荐的方法吗？谢谢。

yeliang2258 commented 2 years ago

可以直接使用paddleinference进行部署，paddleinference可以直接部署。 另外使用TensorRT是可以直接加载我们转换出来的ONNX量化模型的，具体可以参考TensorRT的例子，直接加载ONNX模型。

zhangxianjie1314 commented 2 years ago

好的，谢谢了，我尝试一下

image 为什么TensorRT官网上说不支持int8的onnx进行部署？

yeliang2258 commented 2 years ago

请安装TensorRT8+，具体链接：https://docs.nvidia.com/deeplearning/tensorrt/developer-guide/index.html#working-with-int8 image

yeliang2258 commented 2 years ago

你也可以使用如下类似的命令进行转换： trtexec --onnx=quant_model.onnx --workspace=2048 --explicitBatch --int8

Hi @yeliang2258 , Thanks for your time. I checked that you have already fixed the split issue. However, I have just tried to pull PR #399, but the result is the same.

Hi @yeliang2258 , Regarding the hardwish activation layer, could you take a look: https://github.com/ultralytics/yolov5/issues/825

nongwoluanlai666 commented 2 years ago

@yeliang2258 请问，这两个op支持了么，试过了好多分支了，仍然解决不了，目前的需求是：将paddle模型量化后转为onnx =========== fake_channel_wise_quantize_dequantize_abs_max =========== =========== fake_quantize_dequantize_moving_average_abs_max ===========

yeliang2258 commented 2 years ago

@nongwoluanlai666 用这个PR来转吧：https://github.com/PaddlePaddle/Paddle2ONNX/pull/651 另外，请问你导出为ONNX用什么推理引擎部署呢？

nongwoluanlai666 commented 2 years ago

@yeliang2258 您好，我是打算用在MNN部署的。目前MNN可以用protobuffer 格式作为量化参数的输入，因为不熟悉protobuffer，我用#651导出的txt转换仍有困难; MNN官网的量化参数定义如下： MNN_compression.proto
