MY_*_*Y_G 5 ubuntu bazel tensorflow
我使用 Ubuntu 15.10。目前,我正在按照此处的说明从源代码构建 TensorFlow 。
我的安装成功了,除了最后一步:“Build your target with GPU support”。
当我从源代码树的根运行此命令时:
bazel build -c opt --config=cuda //tensorflow/cc:tutorials_example_trainer
我看到以下输出:
INFO: Found 1 target...
ERROR: /home/me/tensorflow/tensorflow/core/kernels/BUILD:549:1: error while parsing .d file: /home/me/.cache/bazel/_bazel_me/38a03c514c8dc954778fc9a555bce3de/tensorflow/bazel-out/local_linux-opt/bin/tensorflow/core/kernels/_objs/colorspace_op_gpu/tensorflow/core/kernels/colorspace_op_gpu.cu.d (No such file or directory).

有几件事我不明白:
.d文件不见了?nvcc 警告:选项“--relaxed-constexpr”已被弃用并被选项“--expt-relaxed-constexpr”取代。
感谢您的帮助。
考虑安装并临时选择旧版本的gcc:
apt-get install gcc-4.8

然后更新您的替代方案:
update-alternatives --remove-all gcc
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 10

编译 TensorFlow 后,您可以使用以前版本的gcc调用上述命令以及正确的/usr/bin/gcc-5.x.
