custom_models convert error - `Cannot infer shapes or values for node "If_38"`

See original GitHub issue

I wanted to implement custom_model according to your instructions, but the following error occurred when converting to openvino

How did you solve it, could you help me?

[ ERROR ]  Cannot infer shapes or values for node "If_38".
[ ERROR ]  There is no registered "infer" function for node "If_38" with op = "If". Please implement this function in the extensions. 
 For more information please refer to Model Optimizer FAQ, question #37. (https://docs.openvinotoolkit.org/latest/openvino_docs_MO_DG_prepare_model_Model_Optimizer_FAQ.html?question=37#question-37)
[ ERROR ]  
[ ERROR ]  It can happen due to bug in custom shape infer function <UNKNOWN>.
[ ERROR ]  Or because the node inputs have incorrect values/shapes.
[ ERROR ]  Or because input shapes are incorrect (embedded to the model or passed via --input_shape).
[ ERROR ]  Run Model Optimizer with --log_level=DEBUG for more information.
[ ERROR ]  Exception occurred during running replacer "REPLACEMENT_ID" (<class 'extensions.middle.PartialInfer.PartialInfer'>): Stopped shape/value propagation at "If_38" node.

Thank you. I was able to reproduce the issue by using the same versions as you. A short term workaround is to downgrade torch. I am using: torch 1.9.0 torchvision 0.10.0

Dear geaxgx:

We are bad to create this issue on the wrong title. and thanks for your latest repo. we will git pull or download it again. By the way, we seem to find out depthai version is must be lower than 2.19.1.0 We have testing 2.13 or 2.15 with hand tracker. there is no any problem and running very smoothly.

all the best~~
