php tensorflow extension
TensorFlow PHP Extension
PHP Tensorflow is no longer planned. The reason you found this project is to do Tensorflow on the web, there is a better way like tensorflow.js, so try it. https://js.tensorflow.org/
use tensorflow 0.12.0-rc0 c api.
Requirements
-
Environment to build TensorFlow from source code (Linux or Mac OS X). If you'd like to skip reading those details and do not care about GPU support, try the following:
# On Linux sudo apt-get install python swig python-numpy # On Mac OS X with homebrew brew install swig
Installation
-
Download and Build the TensorFlow by Git Submodule.
git submodule update --init --recursive cd lib/tensorflow ./configure bazel build -c opt //tensorflow:libtensorflow.so cp bazel-bin/tensorflow/libtensorflow.so /usr/local/lib -
Build the PHP Extension
phpize ./configure make install
Contributions
This API has been built on top of the C API, which is intended for building language bindings for TensorFlow functionality. However, this is far from complete. Contributions are welcome.
- do not edit
README.mddirectly. editREADME.ok.md. use is your README ok that is preprocessor of Markdown.
Documents
Current useable stuffs.
