Tensorflow：1.11.0 Ubuntu的：18.04 的Python：3.6.6
我使用pyenv用python 3.6.6创建了一个环境，并将tensorflow gpu安装到其中。
已验证的tensorflow GPU装有：
python -c "import tensorflow as tf; print(tf.__version__)"
它返回：1.11.0
然后我尝试运行以下示例代码：https://www.tensorflow.org/tutorials/
我遇到以下错误：
ython 3.6.6 (default, Oct 6 2018, 00:35:42)
[GCC 6.4.0 20180424] on linux
Type "copyright", "credits" or "license()" for more information.
