In my project, there are two networks need to inference In the whole pipeline. So I parser the two model into different engines, contexts, runtime and all that related class have two instances .But when I run it, it will crash in parsering the origin model. The first one will build OK, and the second one will failed to crash , It is the same in reverse models. Why did it happen ? Is there any class may be singleton that I can not create twice or some state need to clear?
