For Git Bash
$ git clone https://github.com/NobuoTsukamoto/edge_tpu.git
$ cd edge_tpu/detection/vc_tflite/
$ git submodule update --init
- For CMake(cmake-gui), Set path and Configure.
- Where is the source code:
PATH_TO\edge_tpu\detection\vc_tflite\tensorflow\tensorflow\lite - Where to build the binaries:
PATH_TO\edge_tpu\detection\vc_tflite\tensorflow\tflite_build
- Where is the source code:
- Set parameters, Configure and Generate.
- TFLITE_ENABLE_MMAP: uncheck
- TFLITE_ENABLE_NNAPI: uncheck
- TFLITE_ENABLE_XNNPACK: uncheck (If checked, a build error will occur *1)
- Open Project(cmake-gui) and launch Visual Studio(tensorflow\tflite_buildtensorflow-lite.sln).
- Select ALL_BUILD project form Solution explorer and Release build.
- After a successful build, copy the *.lib files form Release and _deps directory.
tflite_build\Release\tensorflow-lite.lib tflite_build\_deps\farmhash-build\Release\farmhash.lib tflite_build\_deps\fft2d-build\Release\fft2d_fftsg.lib tflite_build\_deps\fft2d-build\Release\fft2d_fftsg2d.lib tflite_build\_deps\flatbuffers-build\Release\flatbuffers.lib tflite_build\_deps\ruy-build\Release\ruy.lib
Note:
*1: If TFLITE_ENABLE_XNNPACK is checked, the following build error occurs in the pthreadpool project.
fatal error C1083: include Cannot open include file: 'stdatomic.h':No such file or directory
*2: Nothing is copied when CMAKE_INSTALL_PREFIX is set.
- Download libusb-1.0.22 and extract the files to the vc_tflite folder.
vc_tflite +- libedgetpu +- libusb-1.0.22 +- tensorflow
- For Anaconda Powershell Prompt
Note: Workarounds in case of Windows Python related errors.
