arctan 函数不支持 qtensor ，是把这个op 移出量化 q- dq stub 范围之外吗 ？

Lv.5你好。pytorch里面并没有torch.arctan这个API ，但是有torch.atan，包括onnx里面也没有这个arctan的api，有Atan算子。你可以把你的模型里面涉及到的arctan替换成pytorch的torch.atan,重新导出onnx，或者直接修改onnx模型文件蒋arctan修改成Atan算子，这样是等效的。

默认23232回复Huanghui:谢谢答复，arctan 是有的 https://pytorch.org/docs/stable/generated/torch.arctan.html
但 oe-sdk 里面对torch op 只支持 atan ， 改成 atan 是可以的2025-03-050- Huanghui回复默认23232:
好的那我可能是记错了
2025-03-050 - Huanghui回复默认23232:
对的他们两个是等效的替换下就ok
