Posted on In

前篇配置了 Caffe 和 Digits，还有一个框架就是 Google 开发的 TensorFlow。

配置简单，简略配置下：

补充
  • 遇到 Couldn’t open CUDA library libcuda.1.dylib. 或 failed to find libcuda.so on this system: Failed precondition: could not dlopen DSO: libcuda.1.dylib; dlerror: dlopen(libcuda.1.dylib, 5): image not found 问题：

    请确认 LD_LIBRARY_PATH 已配置，并且 libcuda.1.dylib 存在，我这里的情况是 libcuda.dylib 存在，于是我就软连接到 .1.dylib 上，运行成功。
