目前X2Paddle支持40+的TensorFlow OP，40+的Caffe Layer，覆盖了大部分CV分类模型常用的操作。我们在如下模型列表中测试了X2Paddle的转换。

受限于不同框架的差异，部分模型可能会存在目前无法转换的情况，如TensorFlow中包含控制流的模型，NLP模型等。对于CV常见的模型，如若您发现无法转换或转换失败，存在较大diff等问题，欢迎通过[ISSUE反馈](https://github.com/PaddlePaddle/X2Paddle/issues/new)的方式告知我们(模型名，代码实现或模型获取方式)，我们会即时跟进：）

目前onnx2paddle主要支持onnx operator version 9；  
如何将torchvison或者个人开发者写的pytroch model转换成onnx model:
```
import torch
import torchvision

#根据不同模型调整输入的shape
dummy_input = torch.randn(1, 3, 224, 224)

#预训练后的pytorch model
resnet18 = torchvision.models.resnet18(pretrained=True)

#"resnet18.onnx"为onnx model的存储路径，1.1
torch.onnx.export(resnet18, dummy_input, "resnet18.onnx",verbose=True)

```
