"Batch size should be equal to the number of images" error without explanation in OpenVINO

[adammpolak]

I have been trying to run the hello_classification example in my C++ project

I have managed to get it to compile and take in the model as well as network.

I am now receiving this error: "Batch size should be equal to the number of images."

It does not let me know what line in "hello_classification", main.cpp would provide this error, what does it mean?

Heads up, I am providing hello_classification the cv::Mat directly in `Blob::Ptr imgBlob = wrapMat2Blob(image);`

rather than using `cv::Mat image = imread_t(input_image_path);`

(Which means that I am calling `ClassificationResult_t classificationResult(output);` instead of 

`ClassificationResult_t classificationResult(output, {input_image_path});` in step

Hi Adammpolak,

Thank you for reaching out to us and thank you for using the OpenVINO™ toolkit!

Are you using the latest version of the OpenVINO™ toolkit to run the hello_classification example in your C++ project?

Based on the latest version of the OpenVINO™ toolkit, the error you encountered: “Batch size should be equal to the number of images” was caused by the “classification_results.h” file from line 129 to line 131.

For your information, a different version of the OpenVINO™ toolkit, the error will be caused by the same file as well. But the lines that cause the error will differ.

The “classification_results.h” file is located under the following directory:

<INSTALL_DIR>\inference_engine\samples\cpp\common\utils\include\samples\ classification_results.h

Hope it helps.

Regards,

Wan
