Bazel comes with a bash completion script. To install it:
Build it with Bazel: bazel build //scripts:bazel-complete.bash.
Copy the script bazel-bin/scripts/bazel-complete.bash to your completion folder (/etc/bash_completion.d directory under Ubuntu). If you don’t have a completion folder, you can copy it wherever suits you and simply insert source /path/to/bazel-complete.bash in your ~/.bashrc file (under OS X, put it in your ~/.bash_profile file).

采用源码编译安装TensorFlow，在进行TensorFlow配置时，如果系统中没有安装OpenCL而在Do you wish to build TensorFlow with OpenCL support? [y/N]时又选择了y，那么会出现”Invalid SYCL 1.2 library path. /usr/local/computecpp/lib/libComputeCpp.so cannot be found “这个错误。
