解答：
mindspore1.7转onnx格式，Conv2DTranspose已经支持，目前可以在gitee下载源码。mindspore: MindSpore is a new open source deep learning training/inference framework that could be used for mobile, edge and cloud scenarios.
通过编译安装方式安装mindspore1.7：
使用源码编译方式，在不同的环境安装MindSpore，可参考以下文档:
Ascend环境使用源码编译方式安装MindSpore
GPU环境使用源码编译方式安装MindSpore
CPU环境使用源码编译方式安装MindSpore
