New image_classify could not read the binary file and throws an error
E NN_SDK: [read_binary_file:95]Error: NOT A VALID GRAPH BINARY FILE
I used the binary file from AML_NN_SDK/image_classify_88.nb at master · Amlogic-NN/AML_NN_SDK · GitHub

It work for me
Sorry, it works for me as well.
@Frank
In this video (VIM3 - Realtime Object Detection Using Yolo v3 - YouTube), I noticed that you previously had instructions on how to retrain yolov3 to custom objects. Can you tell me where I can find this guide now
@Frank I am using “ssd_mobilenet_v2_coco_2018_03_29” model for my use case.
What do you mean by saying this cannot be converted using conversion tools? Is this model not supported?
Also, I have come across the below mentioned links on khadas documentation.
- Description and Usage of aml_NPU_app Code Repository | Khadas Documentation
- How to Compile and Use Amlogic NN Api demo | Khadas Documentation
- How To Compile And Run Tengine Demo | Khadas Documentation
What is the difference between these? Are there any specialities among each of them? Do all the three use NPU?
I trained and converted my yolov3 model and got the files as for mobile net_tf. I used them in the tutorial and ran the binary file from demo_binaries. However, I want to work with the source code that runs the neural network for integration into my application. I tried to compile my binary files from nbg_unify_my_yolov3 using the following cmake:
cmake_minimum_required(VERSION 3.1)
project(a LANGUAGES C CXX)
add_executable(person_detect "")
find_package(OpenCV REQUIRED)
target_include_directories(person_detect PRIVATE
${CMAKE_CURRENT_LIST_DIR}/

It is going to but when I run it (LD_LIBRARY_PATH=/root/NeuralNetworks/aml_npu_sdk_6.4.3/linux_sdk/linux_sdk_6.4.3/build/sdk/drivers_64/ ./person_detect ../my_yolov3.nb /root/NeuralNetworks/test.bmp)

Please tell me what I did wrong

and what can be the reason for the error " E [vn_CreateMyYolov3:178]Create graph fail."?
or how do you run the files after converting in addition to copying them to the demo
I tried using build_vx.sh and makefile. linux replacing some library paths that were not present at compilation (build_vx.sh and makefile. linux took from. sample_demo_fb). And it helped me to go further, now the network is being created, but I have the following error:
Create Neural Network: 85ms or 85296us
Wrong JPEG library version: library is 90, caller expects 80
libjpeg. a was taken from linux_sdk_6. 4. 3/acuity-ovxlib-dev/lib
I downloaded the SDK 6.4.4.3, but I do not see the linux_sdk folder from which I took the necessary libraries
i solved the problem on the old sdk by taking libjpeg from opencv
@ilya71 , In 6.4.4.3 and later versions, we are not integrating linux_sdk. we just support local compile, it don’t need linux_sdk
Please tell me in the manual (How to convert and call your own model through NPU | Khadas Documentation) “MOdify 1_quantize_model.sh” there is such an action:
Replace the image inside
1 $ cat ./data/validation_tf.txt
2 ./space_shuttle_224.jpg, 813
Modify to,
1 path/to/416x416.jpg
What did 813 mean in this file? And what is it used for?
Also I see in conversion_script datasets.txt with the same content. Do I need to change it?
But it doesn’t explain what the magic number 813 is, which is used in the demo
