Coral issue tracker (and legacy Edge TPU API source)
edgetpurepo is primarily our issue tracker for all types of bugs or feature requests with Coral devices and software.
If you have an issue, please report it here.
The code that remains in this repo is legacy and might be removed in the future.
The following build information is still accurate for the code in this repo, but beware that all the code in here is no longer maintained.
You should instead refer to the following repos:
scripts/runtime/install.shto install Edge TPU runtime or
scripts/runtime/uninstall.shto uninstall it.
scripts/build_swig.shto build SWIG-based native layer for different Linux architectures. Build is Docker-based, so you need to have it installed.
make wheelto generate Python library wheel and then
pip3 install $(ls dist/*.whl)to install it
All native code is inside
srcfolder. You can build everything using
makecommand which invokes Bazel internally.
For example, run
make teststo build all C++ unit tests or
make benchmarksto build all C++ benchmarks. To get the list of all available make targets run
make help. All output goes to
On Linux you can compile natively or cross-compile for 32-bit and 64-bit ARM CPUs.
To compile natively you need to install at least the following packages:
sudo apt-get install -y build-essential \ libpython3-dev \ libusb-1.0-0-dev \
and to cross-compile:
sudo dpkg --add-architecture armhf sudo apt-get install -y crossbuild-essential-armhf \ libpython3-dev:armhf \ libusb-1.0-0-dev:armhf
sudo dpkg --add-architecture arm64 sudo apt-get install -y crossbuild-essential-arm64
Compilation or cross-compilation is done by setting CPU variable for
make CPU=k8 tests # Builds for x86_64 (default CPU value) make CPU=armv7a tests # Builds for ARMv7-A, e.g. Pi 3 or Pi 4 make CPU=aarch64 tests # Builds for ARMv8, e.g. Coral Dev Board
You need to install the following software:
sudo port install python35 python36 python37 py35-numpy py36-numpy py37-numpy
sudo port install libusb
Right after that all normal
makecommands should work as usual. You can run
make teststo compile all C++ unit tests natively on macOS.
Docker allows to avoid complicated environment setup and build binaries for Linux on other operating systems without complicated setup:
make DOCKER_IMAGE=debian:buster DOCKER_CPUS="k8 armv7a aarch64" DOCKER_TARGETS=tests docker-build make DOCKER_IMAGE=ubuntu:18.04 DOCKER_CPUS="k8 armv7a aarch64" DOCKER_TARGETS=tests docker-build
