tensorflow-gpu 的 Pip 安装失败 - OSError：原始写入（）返回无效长度

Question

在 Windows 10 (Python 3.5) 中使用 pip 安装 tensorflow-gpu 1.4.0 时，出现以下奇怪错误。很有意思，每次跑

pip.exe install tensorflow-gpu

它会下载一小部分但看似随机的包，然后引发以下异常：

(C:\Users\carth\Anaconda3\envs\py35) E:\Data\ownCloud\Work\CoronaryML>pip.exe install tensorflow-gpu

我尝试关闭我的杀毒软件，以防万一杀了它，但它没有帮助。

最后，我设法通过手动从 PyPI 下载 .whl 并运行 pip.exe install path/to/.whl 来安装它，但我想了解导致原始故障的原因。

有什么想法吗？

用管理员权限切换到cmd运行命令： pip3 install --ignore-installed --upgrade tensorflow-gpu -i https://pypi.tuna. tsinghua.edu.cn/simple
