如何修复TensorFlow教程(初学者的MNIST)错误

Question

我试图在此处为初学者张紧MNIST教程。

当我执行教程脚本时，会导致以下错误。
如何解决此错误？

似乎无法获取MNIST图像数据。

Error importing tensorflow.  Unless you are using bazel,
you should not try to import tensorflow from its source directory;
please exit the tensorflow source tree, and relaunch your python interpreter
from there.

Answer 1

我认为这不是图像的问题。我认为相关行是：

Library not loaded: @rpath/libcudart.8.0.dylib

您没有加载必要的CUDA库。您打算在CUDA/GPU支持下安装吗？如果是这样，您应该查看有关 TensorFlow安装页面。

Answer 2

您没有在系统上找到CUDA。
