python - 无法在 Windows 中构建 tensorflow C++ API

Question

我按照说明进行了每一步，但它仍然无法构建 https://www.tensorflow.org/install/source_windows

1. 我无法包含 CUDA 库和包含文件，因为 python 脚本在 ./configure.py 阶段无法识别 2 个逗号分隔的路径它只识别我输入的第一个，正如你所看到的，我以相反的顺序输入它们，它看到第一个就好了。 Afaik 这是一个新增功能，因为说明会在不同时间询问路径。

   请指定您要使用的 CUDA SDK 版本。 [留空默认为 CUDA 10]:

   Please specify the cuDNN version you want to use. [Leave empty to default to cuDNN 7]:
   
   Please specify the comma-separated list of base paths to look for CUDA libraries and headers. [Leave empty to use the default]: C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\include, C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\lib\x64

所以我必须禁用 CUDA 支持然后我只是想构建 DLL我得到了这些乱七八糟的错误

我已经按照 github 上的一个问题中的建议添加到 WORKSPACE 文件的顶部

http_archive(
    name = "io_bazel_rules_docker",
    sha256 = "87fc6a2b128147a0a3039a2fd0b53cc1f2ed5adb8716f50756544a572999ae9a",
    strip_prefix = "rules_docker-0.8.1",
    urls = ["https://github.com/bazelbuild/rules_docker/archive/v0.8.1.tar.gz"],
)

我如何克服这些错误？

为什么对 C++ 的支持这么差，据我所知，每个人都使用带有 C++ 的 tensorflow 进行推理。我无法想象所有的自动驾驶汽车都在 python 上运行

Answer 1

通过运行命令修复

c:\msys32\usr\bin\sed -ri "/^\W+sha256 = \"[^\"]+\"\W+$/d" tensorflow/workspace.bzl

完全禁用校验和验证 https://github.com/tensorflow/tensorflow/issues/12979

那我还需要做

c:\msys32\usr\bin\pacman.exe -S git patch unzip

并添加 BAZEL_SH 环境变量 c:\msys32\usr\bin\bash.exe
