      1 # TensorFlow in Go
      2 
      3 Construct and execute TensorFlow graphs in Go.

      7 > *WARNING*: The API defined in this package is not stable and can change
      8 > without notice. The same goes for the awkward package path
      9 > (`github.com/tensorflow/tensorflow/tensorflow/go`).
     10 
     11 ## Quickstart
     12 
     13 Refer to [Installing TensorFlow for Go](https://www.tensorflow.org/install/install_go)
     14 
     15 ## Building the TensorFlow C library from source
     16 
     17 If the "Quickstart" instructions above do not work (perhaps the release archives
     18 are not available for your operating system or architecture, or you're using a
     19 different version of CUDA/cuDNN), then the TensorFlow C library must be built
     20 from source.
     21 
     22 ### Prerequisites
     23 
     24 -   [bazel](https://www.bazel.build/versions/master/docs/install.html)
     25 -   Environment to build TensorFlow from source code
     26     ([Linux](https://www.tensorflow.org/install/install_sources#PrepareLinux)
     27     or [OS
     28     X](https://www.tensorflow.org/install/install_sources#PrepareMac)).
     29     If you don't need GPU support, then try the following:
     30 
     31     ```sh
     32     sudo apt-get install python swig python-numpy # Linux
     33     brew install swig                             # OS X with homebrew
     34     ```
     35 
     36 ### Build
     37 
     38 1.  Download the source code
     39 
     40     ```sh
     41     go get -d github.com/tensorflow/tensorflow/tensorflow/go
     42     ```
     43 
     44 2.  Build the TensorFlow C library:
     45 
     46     ```sh
     47     cd ${GOPATH}/src/github.com/tensorflow/tensorflow
     48     ./configure
     49     bazel build --config opt //tensorflow:libtensorflow.so
     50     ```
     51 
     52     This can take a while (tens of minutes, more if also building for GPU).
     53 
     54 3.  Make `libtensorflow.so` available to the linker. This can be done by either:
     55 
     56     a. Copying it to a system location, e.g.,
     57 
     58     ```sh
     59     sudo cp ${GOPATH}/src/github.com/tensorflow/tensorflow/bazel-bin/tensorflow/libtensorflow.so /usr/local/lib
     60     ```
     61 
     62     OR
     63 
     64     b. Setting environment variables:
     65 
     66     ```sh
     67     export LIBRARY_PATH=${GOPATH}/src/github.com/tensorflow/tensorflow/bazel-bin/tensorflow
     68     # Linux
     69     export LD_LIBRARY_PATH=${GOPATH}/src/github.com/tensorflow/tensorflow/bazel-bin/tensorflow
     70     # OS X
     71     export DYLD_LIBRARY_PATH=${GOPATH}/src/github.com/tensorflow/tensorflow/bazel-bin/tensorflow
     72     ```
     73 
     74 4.  Build and test:
     75 
     76     ```sh
     77     go test github.com/tensorflow/tensorflow/tensorflow/go
     78     ```
     79 
     80 ### Generate wrapper functions for ops
     81 
     82 Go functions corresponding to TensorFlow operations are generated in `op/wrappers.go`. To regenerate them:
     83 
     84 Prerequisites:
     85 - [Protocol buffer compiler (protoc) 3.x](https://github.com/google/protobuf/releases/)
     86 - The TensorFlow repository under GOPATH
     87 
     88 ```sh
     89 go generate github.com/tensorflow/tensorflow/tensorflow/go/op
     90 ```
     91 
     92 ## Support
     93 
     94 Use [stackoverflow](http://stackoverflow.com/questions/tagged/tensorflow) and/or
     95 [Github issues](https://github.com/tensorflow/tensorflow/issues).
     96 
     97 ## Contributions
     98 
     99 Contributions are welcome. If making any signification changes, probably best to
    100 discuss on a [Github issue](https://github.com/tensorflow/tensorflow/issues)
    101 before investing too much time. Github pull requests are used for contributions.
