Ubuntu TensorFlow（GPU）libcudart.so.7.5错误--无法打开共享对象文件

在Ubuntu 14.04上安装带有GPU的TensorFlow。对于Ubuntu/UNIX环境来说是相当新的，所以很多东西我都不懂。在搜索此问题时，我遇到了安装了CUDA 7.5后无法导入CUDA 7.0的实例（因为TensorFlow不支持7.5）。我已经安装了CUDA 7.0，但它似乎在寻找7.5-这是为什么？我的.bashrc文件中有以下几行：

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda-7.0/lib64"
export CUDA_HOME=/usr/local/cuda-7.0

但我仍然看到下面的问题。。。有人有什么建议吗

ImportError:libcudart.so.7.5:无法打开共享对象文件：没有此类文件或目录

我也有同样的问题。您是否尝试过将CUDA 7.5与CUDA 7一起安装？这对我来说很有效，我将路径变量改为包含7.5而不是7.0。如果您使用的是最新的r0.7二进制文件，根据我的经验，它们现在默认构建为支持CUDA 7.5…而r0.6二进制文件与CUDA 7.0一起工作

您可以从源代码构建tensorflow来使用CUDA 7.0，请参见此处的文档

---

您需要从安装tensorflow来配置设置。通过pip或easy_安装将不起作用

在使用pip将tensorflow从0.6.0升级到0.7.1后，我也遇到了同样的问题。

我在安装CUDA 7.5时遇到了安装问题，由于某些原因，我无法找到要运行的配置文件，以指定要使用哪个版本的CUDA。我可能会尝试安装TensorFlow 0.7.0，因为我认为它默认为7.0。是的，我看到了，但无法找到配置文件来更改它使用的库。通过安装TensorFlow 0.7.0（默认为CUDA 7.0），我暂时“解决”了我的问题……在您进行git克隆后，配置脚本位于顶级TensorFlow源目录中
