感谢您的所有建议.我尝试使用

Thank you for all your suggestions. I tried installing the CPU only version of TensorFlow using

{
pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.0.1-py2-none-any.whl
}

解决了问题.有趣的是消息指出我没有使用 GPU.

which fixed the problem. The interesting thing were the messages stating that I was not using the GPU.
