在Ubuntu 16.04 w/GPU上構建TensorFlow源代碼：`GLIBCXX_3.4.20'找不到

Question

我在Ubuntu 16.04上，並且試圖根據this從源代碼構建支持GPU的TensorFlow。一切工作正常，直到「構建TensorFlow」步驟，其中我執行：

bazel build -c opt --config=cuda //tensorflow/tools/pip_package:build_pip_package 

編譯命中誤差與輸出：

ERROR: /home/thomas/tensorflow/tensorflow/core/BUILD:978:28: Executing genrule //tensorflow/core:proto_text_srcs_all failed: bash failed: error executing command /bin/bash -c ... (remaining 1 argument(s) skipped): com.google.devtools.build.lib.shell.BadExitStatusException: Process exited with status 1.

我的懷疑是錯誤有事情做與蟒蛇因爲bazel似乎在從〜/ anaconda2/lib中尋找libstdC++。

Answer 1

此命令似乎解決我的問題：

conda install libgcc 

從here。

Answer 2

編輯：費曼27的解決方案似乎更清潔，先試一下。

有同樣的問題。這些步驟已經解決了這個問題對我來說（根，加sudo需要時）：

1. 獲取最新的libstdC++提供6（可能不需要）：

   add-apt-repository ppa:ubuntu-toolchain-r/test apt-get update apt-get upgrade

2. 更新的符號鏈接中ananconda，我做到了在蟒蛇我python2 ENV，也許你需要直接做在〜/蟒蛇/ lib目錄下：

   cd ~/anaconda2/envs/python2/lib mv libstdc++.so libstdc++.so.backup mv libstdc++.so.6 libstdc++.so.6.backup ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 libstdc++.so ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 libstdc++.so.6
