Expected Tensor but got Tuple debug_handle:-1

[dipendra009]

Hi,
I was able to export the yolov5s model to tflite format as suggested using export.py. However, when I build on mac, I get the following errors:

[W TensorImpl.h:1156] Warning: Named tensors and all their associated APIs are an experimental feature and subject to change. Please do not use them for anything important until they are released as stable. (function operator())
