ptorch 转换失败（rk3568）

平台为 rk3568，训练好的pytorch模型，按照example进行转换，失败，提示如下信息：RuntimeError: [enforce fail at inline_container.cc:222] . file not found: archive/constants.pkl
请问是不是对pytorch的版本有要求啊？

将pth模型转换为 torchscript 后，报错如下：
这个 rknn-toolkit2 没有对应的 ['aten::clamp_min'] 吗？

是的，从log来看就是aten::clamp_min这个算子不支持。
那就有3种做法：
要么你自定义op，
要么改模型改掉这个op
要么如果这个op在头或者尾，就拉出来自己实现，不用放rknn里
