torch转paddle时报错：'PaddleGraph' object has no attribute 'script'

[gyr-kdgc]

问题描述

运行的代码如下（注释部分为torch.save(model.state_dict(), "model_torch16.pt")格式保存的模型，可以转换成功，但是现在想转换torch的script model，转换失败了）：

import torch from x2paddle.convert import pytorch2paddle from model import resnet

trained_model = resnet.resnet50(num_classes=2, include_top=True)

trained_model.load_state_dict(torch.load("model_torch16.pt"))

trained_model=torch.jit.load("model_script_torch16.pt") tensor_shape=[1,3,224,224] input_tensor = torch.zeros_like(torch.empty(tuple(tensor_shape))) pytorch2paddle(module=trained_model, save_dir="./output22", jit_type="trace", input_examples=[input_tensor])

具体信息

pytorch==1.6.0 x2paddle==1.2.0

torch模型保存方式（script model）： x = torch.randn(1, 3, 224, 224, requires_grad=True).cuda() script_module = torch.jit.trace(model, x, strict=False) torch.jit.save(script_module, "model_script_torch16.pt")

具体报错信息如下： /opt/miniconda3/lib/python3.7/site-packages/setuptools/depends.py:2: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses import imp ['1', '6', '0'] Now translating model from pytorch to paddle. /opt/miniconda3/lib/python3.7/site-packages/torch/jit/init.py:948: UserWarning: The input to trace is already a ScriptModule, tracing it is a no-op.

@gyr-kdgc 麻烦更新到最新版本X2Paddle试试(1.3.8)

另外，可以描述一下以下两个问题吗： 1、具体业务场景 2、为什么有转到Paddle部署的需求呢？
