tensorflow: macbook pro GPU version, successfully opened CUDA library, but not found the GPU

Hi ALL: I am a chinese student, so may be English is bas. Sorry. now I use the tensorflow GPU version. I user the pip to down the python3 GPU version, and down the all about the GPU file. But i can successfully opened CUDA library, but not found the GPU, like this: In [1]: import tensorflow as tf I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcublas.dylib locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcudnn.dylib locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcufft.dylib locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcuda.1.dylib locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcurand.dylib locally

In [2]: tf.Session() E tensorflow/stream_executor/cuda/cuda_driver.cc:491] failed call to cuInit: CUDA_ERROR_NO_DEVICE I tensorflow/stream_executor/cuda/cuda_diagnostics.cc:153] retrieving CUDA diagnostic information for host: wangxiaoweideWindows.local I tensorflow/stream_executor/cuda/cuda_diagnostics.cc:160] hostname: wangxiaoweideWindows.local I tensorflow/stream_executor/cuda/cuda_diagnostics.cc:185] libcuda reported version is: 346.3.6 I tensorflow/stream_executor/cuda/cuda_diagnostics.cc:189] kernel reported version is: Invalid argument: expected %d.%d or %d.%d.%d form for driver version; got "" I tensorflow/core/common_runtime/gpu/gpu_init.cc:81] No GPU devices available on machine.

and I find the I can’t deviceQuery the GPU:

now I use the mac os, and Xcode8, how to solve it ?
