            OpenVino converted model not returning same score values as original model (Sigmoid)
            Asked 2022-Jan-05 at 06:06

            I've converted a Keras model for use with OpenVino. The original Keras model used sigmoid to return scores ranging from 0 to 1 for binary classification. After converting the model for use with OpenVino, the scores are all near 0.99 for both classes but seem slightly lower for one of the classes.

            For example, test1.jpg and test2.jpg (from opposite classes) yield scores of 0.00320357 and 0.9999, respectively.

            With OpenVino, the same images yield scores of 0.9998982 and 0.9962392, respectively.

            Edit* One suspicion is that the input array is still accepted by the OpenVino model but is somehow changed in shape or "scrambled" and therefore is never a match for class one? In other words, if you fed it random noise, the score would also always be 0.9999. Maybe I'd have to somehow get the OpenVino model to accept the original shape (1,180,180,3) instead of (1,3,180,180) so I don't have to force the input into a different shape than the one the original model accepted? That's weird though because I specified the shape when making the xml and bin for openvino:



            Answered 2022-Jan-05 at 06:06

            Generally, Tensorflow is the only network with the shape NHWC while most others use NCHW. Thus, the OpenVINO Inference Engine satisfies the majority of networks and uses the NCHW layout. Model must be converted to NCHW layout in order to work with Inference Engine.

            The conversion of the native model format into IR involves the process where the Model Optimizer performs the necessary transformation to convert the shape to the layout required by the Inference Engine (N,C,H,W). Using the --input_shape parameter with the correct input shape of the model should suffice.

            Besides, most TensorFlow models are trained with images in RGB order. In this case, inference results using the Inference Engine samples may be incorrect. By default, Inference Engine samples and demos expect input with BGR channels order. If you trained your model to work with RGB order, you need to manually rearrange the default channels order in the sample or demo application or reconvert your model using the Model Optimizer tool with --reverse_input_channels argument.

            I suggest you validate this by inferring your model with the Hello Classification Python Sample instead since this is one of the official samples provided to test the model's functionality.

            You may refer to this "Intel Math Kernel Library for Deep Neural Network" for deeper explanation regarding the input shape.



            Can I specify the type for iterators based on closures?
            Asked 2021-Dec-22 at 19:37

            I wrote a function to iterate over neighbors of cells in a 2d grid:



            Answered 2021-Dec-22 at 19:37

            If I understand correctly, returning an impl would result in slower code, calling function pointers instead of compiling things down to simple loops. Right?

            Nope. Returning impl Iterator is exactly the same, codegen-wise, as returning Map<...>>>.¹ The difference is twofold:

            • Changing the return type of neighbours does not require changing its signature, so impl Iterator is forward-compatible with changes to its return type.
            • impl Iterator won't unify with other opaque impl Iterator types, even if they happen to have the same underlying type. (In simple terms: the compiler won't allow you to make a Vec of impl Iterators from different sources, even if all those opaque types are the same concrete type.)

            Neither of these differences has any influence on code generation or the compiler's ability to inline anything, so go ahead and use impl Iterator.

            There is one case where you must still use indirect dispatch (dyn Iterator): when the function neighbours is itself part of a trait, the impl Trait syntax is not yet available (as of 1.59). The best way to solve this at the moment is to return Box. (Note, however, that doesn't mean every call will be dynamically dispatched; the call to .next() will be, but everything "inside" that still uses easily-optimized static dispatch.)

            Related questions

            ¹ Note that in order to actually return Map<...>>>, you would still have to use impl Trait to represent the closures, since they have anonymous types.



            Why is a = null ?? [] of type never[]?
            Asked 2021-Dec-22 at 07:15

            Why am I getting different type inference here for the array ?



            Answered 2021-Dec-21 at 14:51

            The "correct" thing to do would be to infer never[] for the empty array literal [], because the type of an array literal is the join of the types of its elements, and never is the join of an empty set.

            However, since inferring never[] is usually not what the user intends when writing const a = [], this particular case received a very special treatment in the compiler, and now it starts by implicitly inferring any[], and then refining the type based on the subsequent control flow.

            There does not seem to be any deeper meaning behind it: it's just what turns out to be the most useful in most cases.

Why cannot infer that the type of target is HTMLInputElement when know the value is a string?

            I was figuring out how to do floor/ceiling operations without the math module. I solved this by using floor division //, and found out that the negative "gives the ceiling". So this works:



            Answered 2021-Oct-17 at 09:07

            Python uses the symbol - as both a unary (-x) and a binary (x-y) operator. These have different operator precedence.

            In specific, the ordering wrt // is:

            • unary -
            • binary //
            • binary -

            By introducing a 0 as 0--3//2, the first - is a binary - and is applied last. Without a leading 0 as --3//2, both - are unary and applied together.

            The corresponding evaluation/syntax tree is roughly like this, evaluating nodes at the bottom first to use them in the parent node:
