Hi all,
Here is an example of installation of Deepspeech under the nice JETSON TX2 board.
Should work, too, on TX1.
1/ install L4T v 28.2.1, cuda 9, cudnn…
Create a swapdisk >=8Go (https://github.com/jetsonhacks/installTensorFlowTX2/blob/master/createSwapfile.sh)
2/install Bazel 0.10.0 (aarch64 ok)
wget --no-check-certificate https://github.com/bazelbuild/bazel/releases/download/0.10.0/bazel-0.10.0-dist.zip
unzip bazel-0.10.0-dist.zip -d bazel-0.10.0-dist
cd bazel-0.10.0-dist
sudo chmod +x compile.sh
./compile.sh
cp output/bazel /usr/local/bin
3/build Tensorflow :
-
for python 2.x: sudo apt-get install python-numpy python-dev python-pip python-wheel
-
for python 3.x: sudo apt-get install python3-numpy python3-dev python3-pip python3-wheel
-
cd tensorflow # cd to the top-level directory created
-
./configure
Please specify the location of python. [Default is /usr/bin/python]: /usr/bin/python2.7 Found possible Python library paths: /usr/local/lib/python2.7/dist-packages /usr/lib/python2.7/dist-packages Please input the desired Python library path to use. Default is [/usr/lib/python2.7/dist-packages] Using python library path: /usr/local/lib/python2.7/dist-packages Please specify optimization flags to use during compilation when bazel option "--config=opt" is specified [Default is -march=native]: Do you wish to use jemalloc as the malloc implementation? [Y/n] n Do you wish to build TensorFlow with Google Cloud Platform support? [y/N] N Do you wish to build TensorFlow with Hadoop File System support? [y/N] N Do you wish to build TensorFlow with the XLA just-in-time compiler (experimental)? [y/N] N Do you wish to build TensorFlow with VERBS support? [y/N] N Do you wish to build TensorFlow with OpenCL support? [y/N] N Do you wish to build TensorFlow with CUDA support? [y/N] Y Do you want to use clang as CUDA compiler? [y/N] N Please specify the CUDA SDK version you want to use. [Leave empty to default to CUDA 9.0]: Please specify the location where CUDA 9.0 toolkit is installed. Refer to README.md for more details. [Default is /usr/local/cuda]: Please specify which gcc should be used by nvcc as the host compiler. [Default is /usr/bin/gcc]: Please specify the cuDNN version you want to use. [Leave empty to default to cuDNN 7.0]: Please specify the location where cuDNN 7 library is installed. Refer to README.md for more details. [Default is /usr/local/cuda]: Please specify a list of comma-separated CUDA compute capabilities you want to build with. **6.2** Do you wish to build TensorFlow with MPI support? [y/N] N Configuration finished -
bazel build --config=opt --config=cuda //tensorflow/tools/pip_package:build_pip_package
-
bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
-
sudo pip install /tmp/tensorflow_pkg/tensorflow*
validate tensorflow :
Python
import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))
You should obtain :
Hello, TensorFlow!
Tensorflow installed !
4/build Deepspeech :
- git clone https://github.com/mozilla/DeepSpeech.git
- cd Deepspeech
- pip3 install -r requirements.txt
- cd tensorflow
- ln -s ../DeepSpeech/native_client ./
---
# Native_client BUILD
- bazel build -c opt --config=cuda --copt=-O3 --define=target_system=rpi3-armv8 --copt=-march=armv8-a --copt=-mtune=cortex-a57 --copt=-DRASPBERRY_PI //native_client:libctc_decoder_with_kenlm.so

- cd ../DeepSpeech/native_client
- make deepspeech
- PREFIX=/usr/local sudo make install
---
# Python bindings
under native_client :
- make bindings
- sudo pip install dist/deepspeech*
Finished !
