Before vx-delegate, you may have nnapi-linux version from VeriSilicon, we suggest you move to this new delegate because: 3 | 4 | 1. without nnapi, it's flexible to enable more AI operators. 5 | 2. vx-delegate is opensourced, and will promised compatible with latest tensorflow release(currently v2.14.0). 6 | # Use tflite-vx-delegate 7 | 8 | ## Prepare source code 9 | ```sh 10 | mkdir wksp && cd wksp 11 | # tim-vx is optional, it will be downloaded by CMake automatically for none-cross build 12 | # if you want to do cross build with cmake, you have to build tim-vx firstly 13 | git clone https://github.com/VeriSilicon/TIM-VX.git tim-vx 14 | git clone https://github.com/VeriSilicon/tflite-vx-delegate.git 15 | # tensorflow is optional, it will be downloaded automatically if not present 16 | git clone https://github.com/tensorflow/tensorflow.git 17 | ``` 18 | # Build from source with cmake 19 | 20 | ```sh 21 | # default built for x86-64 simulator 22 | cd tflite-vx-delegate 23 | mkdir build && cd build 24 | cmake .. 25 | make vx_delegate -j12 26 | 27 | # benchmark_model 28 | make benchmark_model -j12 29 | # label_image 30 | make label_image -j12 31 | ``` 32 | If you would like to build with your own vivante driver sdk and tim-vx build, you need do cross-build as 33 | ```sh 34 | cd tim-vx 35 | mkdir build && cd build 36 | cmake .. -DCMAKE_TOOLCHAIN_FILE= -DEXTERNAL_VIV_SDK= 37 | # we can also build from a specific ovxlib instead of use default one by set 38 | # TIM_VX_USE_EXTERNAL_OVXLIB=ON 39 | # OVXLIB_INC= 40 | # OVXLIB_LIB= 41 | ``` 42 | 43 | If you would like to build using local version of tensorflow, you can use `FETCHCONTENT_SOURCE_DIR_TENSORFLOW` cmake variable. Point this variable to your tensorflow tree. For additional details on this variable please see the [official cmake documentation](https://cmake.org/cmake/help/latest/module/FetchContent.html#command:fetchcontent_populate) 44 | 45 | ``` sh 46 | cmake -DFETCHCONTENT_SOURCE_DIR_TENSORFLOW=/my/copy/of/tensorflow \ 47 | -DOTHER_CMAKE_DEFINES...\ 48 | .. 49 | ``` 50 | After cmake execution completes, build and run as usual. Beware that cmake process will apply a patch to your tensorflow tree. The patch is requred to enable the external delegate support and the NBG support. 51 | 52 | ## Enable external delegate support in benchmark_model/label_image 53 | 54 | For tensorflow v2.8.0, addtional patch `pwd`/patches/0001-TensorFlow-V280-Enable-External-Delegate.patch requred to enable enable external delegate in benchmark_model/label_image. For higher versions of TensorFlow, the benchmark_model has automatically enabled the external delegate mechanism, but it is still necessary to apply patch `pwd`/patches/label_image_support.patch to enable the external delegate in label_image. 55 | If tensorflow source code downloaded by cmake, you can find it in /_deps/tensorflow-src 56 | 57 | The patch get merged into Tensorflow master branch, no patch required for master branch. 58 | 59 | ## benchmark_model/label_image compatible with Tflite+NBG 60 | With our Acuity Toolkit, you can generate tflite file with compiled NBG(**N**etwork **B**inary **G**raph) as a custom operator. To support this special format, you should build benchmark_model/label_image from our delegate repo and not use the offical one. 61 | 62 | ## Run 63 | ```sh 64 | # For default x86 build, you can find prebuilt sdk from tim-vx 65 | # export VSIMULATOR_CONFIG= for x86-simulator 66 | export VIVANTE_SDK_DIR= 67 | # Please copy libtim-vx.so to drivers/ directory 68 | export LD_LIBRARY_PATH=${VIVANTE_SDK_DIR}/drivers:$LD_LIBRARY_PATH # the "drivers" maybe named as lib 69 | ./benchmark_model --external_delegate_path= --graph= 70 | # If you would like to use cache mode which save and load binary graph in local disk 71 | ./benchmark_model --external_delegate_path= \ 72 | --external_delegate_options='allowed_cache_mode:true;cache_file_path:' \ 73 | --graph= 74 | ``` 75 | 76 | ## Test 77 | Introduced unit test with tensorflow keras api and convert it to tflite with quantized or none-quantized model, 78 | Golden generated from CPU implementation of tflite 79 | [Details for run test](./test/python/README.md) 80 | 81 | [Model verification script](./test/python/run_model.py) to compare NPU result with CPU result 82 | 83 | # Examples 84 | examples/python/label_image.py 85 | modified based on [offical label_image](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/lite/examples/python/label_image.py) 86 | 87 | 1. build tensorflow-lite runtime python package follow by [offical build instruction](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/lite/tools/pip_package#readme) 88 | 2.

Turn option TFLITE_ENABLE_MULTI_DEVICE to On in ./CMakeLists.txt or Add -DTFLITE_ENABLE_MULTI_DEVICE when build cmake 8 | 2. Only 40 bit driver support this feature, EXTERNAL_VIV_SDK should be setted to point to 40 bit driver location when build TIM_VX cmake 9 | 3. TIM_VX should open TIM_VX_ENABLE_PLATFORM 10 | 11 | #### Step 2.
