我正在尝试在运行Conda的Ubuntu 16.04中使用一些python库(支持GPU的tensorflow,opencv和gdal)及其各种依赖项来启动一个nvidia-docker(2.0)容器.

问题的一般解释

我需要在该环境中使用pip安装一些库(例如tensorflow-gpu 1.10.0和其他一些自定义库),但是无论何时我尝试使用pip在我的Dockerfile中安装包,或者之后,我得到以下错误：

Exception:

如果我尝试使用pip而不是conda install安装其他软件包,则会出现同样的错误(我尝试过的其他软件包是setuptools,h5py,以及其他几个我不记得了)

Dockerfile

这是用于生成此的Dockerfile,直到抛出错误的位置(安装tensorflow时)：

最后一个RUN命令抛出错误.

我尝试过的事情：

>不同版本的点子(10.0.1和18.0)
> pip upgrade pip或conda upgrade pip(尝试以这种方式更新pip会抛出同样的错误)
>更新setuptools(如果我尝试用pip执行它会抛出相同的错误)
>我已经通过预先设置echo $(pip)&& amp;来检查以确保使用了正确的pip.在我的pip install命令之前 – 它返回虚拟环境的pip.

我只是使用conda安装所有内容并忽略它,但我的组内部有几个库不适用于conda.
