### Cross-building for RPi3 ARMv7 / LePotato ARM64
|
||||||
|
|
||||||
|
We do support cross-compilation ; please refer to our `mozilla/tensorflow` fork, where we define the following `--config` flags:
|
||||||
|
- `--config=rpi3` and `--config=rpi3_opt` for Raspbian / ARMv7
|
||||||
|
- `--config=rpi3-armv8` and `--config=rpi3-armv8_opt` for ARMBian / ARM64
|
||||||
|
|
||||||
|
So your command line for RPi3 / ARMv7 should look like:
|
||||||
|
```
|
||||||
|
bazel build --config=monolithic --config=rpi3 --config=rpi3_opt -c opt --copt=-O3 --copt=-fvisibility=hidden //native_client:libdeepspeech.so //native_client:generate_trie
|
||||||
|
```
|
||||||
|
|
||||||
|
And your command line for LePotato / ARM64 should look like:
|
||||||
|
```
|
||||||
|
bazel build --config=monolithic --config=rpi3-armv8 --config=rpi3-armv8_opt -c opt --copt=-O3 --copt=-fvisibility=hidden //native_client:libdeepspeech.so //native_client:generate_trie
|
||||||
|
```
|
||||||
|
|
||||||
|
While we test only on RPi3 Raspbian Stretch / LePotato ARMBian stretch, anything compatible with `armv7-a cortex-a53` / `armv8-a cortex-a53` should be fine.
|
||||||
|
|
||||||
|
The `deepspeech` binary can also be cross-built, with `TARGET=rpi3` or `TARGET=rpi3-armv8`. This might require you to setup a system tree using the tool `multistrap` and the multitrap configuration files: `native_client/multistrap_armbian64_stretch.conf` and `native_client/multistrap_raspbian_stretch.conf`.
|
||||||
|
The path of the system tree can be overridden from the default values defined in `definitions.mk` through `RASPBIAN` make variable.
|
||||||
|
|
||||||
|
```
|
||||||
|
cd ../DeepSpeech/native_client
|
||||||
|
make TARGET=<system> deepspeech
|
||||||
|
```
|
||||||
|
|
||||||
|
### Android devices
|
||||||
|
|
||||||
|
We have preliminary support for Android relying on TensorFlow Lite, with upcoming Java / JNI bindinds. For more details on how to experiment with those, please refer to `native_client/java/README.md`.
|
||||||
|
|
||||||
|
Please refer to TensorFlow documentation on how to setup the environment to build for Android (SDK and NDK required).
|
||||||
|
|
||||||
|
You can build the `libdeepspeech.so` using (ARMv7):
|
||||||
|
|
||||||
|
```
|
||||||
|
bazel build --config=monolithic --config=android --config=android_arm --action_env ANDROID_NDK_API_LEVEL=21 --cxxopt=-std=c++11 --copt=-D_GLIBCXX_USE_C99 //native_client:libdeepspeech.so
|
||||||
|
```
|
||||||
|
|
||||||
|
Or (ARM64):
|
||||||
|
```
|
||||||
|
bazel build --config=monolithic --config=android --config=android_arm64 --action_env ANDROID_NDK_API_LEVEL=21 --cxxopt=-std=c++11 --copt=-D_GLIBCXX_USE_C99 //native_client:libdeepspeech.so
|
||||||
|
```
|
||||||
|
|
||||||
|
Building the `deepspeech` binary will happen through `ndk-build` (ARMv7):
|
||||||
|
|
||||||
|
```
|
||||||
|
cd ../DeepSpeech/native_client
|
||||||
|
$ANDROID_NDK_HOME/ndk-build APP_PLATFORM=android-21 APP_BUILD_SCRIPT=$(pwd)/Android.mk NDK_PROJECT_PATH=$(pwd) APP_STL=c++_shared TFDIR=$(pwd)/../../tensorflow/ TARGET_ARCH_ABI=armeabi-v7a
|
||||||
|
```
|
||||||
|
|
||||||
|
And (ARM64):
|
||||||
|
```
|
||||||
|
cd ../DeepSpeech/native_client
|
||||||
|
$ANDROID_NDK_HOME/ndk-build APP_PLATFORM=android-21 APP_BUILD_SCRIPT=$(pwd)/Android.mk NDK_PROJECT_PATH=$(pwd) APP_STL=c++_shared TFDIR=$(pwd)/../../tensorflowx/ TARGET_ARCH_ABI=arm64-v8a
|
||||||
|
```
|
||||||

DeepSpeech Java / Android bindings
|
||||||
|
==================================
|
||||||
|
|
||||||
|
This is still preliminary work. Please refer to `native_client/README.md` for
|
||||||
|
building `libdeepspeech.so` and `deepspeech` binary for Android on ARMv7 and
|
||||||
|
ARM64 arch.
|
||||||
|
|
||||||
|
Running `deepspeech` via adb
|
||||||
|
============================
|
||||||
|
You should use `adb push` to send data to device, please refer to Android
|
||||||
|
documentation on how to use that.
|
||||||
|
|
||||||
|
Please push DeepSpeech data to `/sdcard/deepspeech/`, including:
|
||||||
|
- `output_graph.tflite` which is the TF Lite model
|
||||||
|
- `alphabet.txt`
|
||||||
|
- `lm.binary` and `trie` files, if you want to use the language model ; please
|
||||||
|
be aware that too big language model will make the device run out of memory
|
||||||
|
|
||||||
|
Then, push binaries from `native_client.tar.xz` to `/data/local/tmp/ds`:
|
||||||
|
- `deepspeech`
|
||||||
|
- `libdeepspeech.so`
|
||||||
|
- `libc++_shared.so`
|
||||||
|
|
||||||
|
You should then be able to run as usual, using a shell from `adb shell`:
|
||||||
|
```
|
||||||
|
user@device$ cd /data/local/tmp/ds/
|
||||||
|
user@device$ LD_LIBRARY_PATH=$(pwd)/ ./deepspeech [...]
|
||||||
|
```
|
||||||
|
|
||||||
|
Please note that Android linker does not support `rpath` so you have to set
|
||||||
|
`LD_LIBRARY_PATH`. Properly wrapped / packaged bindings does embed the library
|
||||||
|
at a place the linker knows where to search, so Android apps will be fine.
