Error in Infer

Hello Everyone

I am trying to convert frozen tensoflow model to IR and getting following error

Cannot infer shapes or values for node "detector/yolo-v3/strided_slice".

strided_slice node is created in tensorflow by the line

inputs = inputs[:, 2:-2, 2:-2, :]

What am i missing ?

Thanks

Hi Yatish,

If the input dimensions are in that format MO cannot interpret them for that node. Can you send the full log of the error from MO?

Kind Regards,

Monique Jones

After modifying my tensorflow model to folowing

test = inputs.shape

# trim back to desired size
inputs = inputs[:, 2:test[1]-2, 2:test[2]-2, :]

i moved forward with the conversion, but it still failed with following error message
