AttributeError: module 'onnxruntime' has no attribute 'InferenceSession'

Hi, All the members of Github.
It's a great opportunity to use onnxruntime package as a new AI developer.
I have some problems with using onnxruntime package, that is the error: AttributeError: module 'onnxruntime' has no attribute 'InferenceSession'.
Initially, I used onnxruntime-gpu v 1.16.3 and It worked well, there is no issue like AttributeError: module 'onnxruntime' has no attribute 'InferenceSession'.
But I upgraded the onnxruntime-gpu from 1.16.3 to 1.18.1 and occurred an error.
I can't figure out this issue. Doesn't the onnxruntime package upper 1.16.3 support InferenceSession?
If it is right, what is the other way instead of InferenceSession?
I would appreciate your help as soon as possible.

Can you show the smallest example of what you're doing that causes the error? It sounds like it could be similar to this issue: #8623

Specifically, try this: Running help(rt) after import onnxruntime as rt to see if it's what you expect it to be.
