tensorflow: TF 1.6 cannot be installed on MacOS because of failure in installing grpcio

System information

• Have I written custom code (as opposed to using a stock example script provided in TensorFlow): No
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): MacOS 10.13.3
• TensorFlow installed from (source or binary): both
• TensorFlow version (use command below): 1.6
• Python version: 3.6.4
• Bazel version (if compiling from source): 0.11
• GCC/Compiler version (if compiling from source):
• CUDA/cuDNN version: -
• GPU model and memory: -
• Exact command to reproduce:

On MacOS, type: sudo pip3 install tensorflow pip3 will start installing grpcio, but an error during the installation of grpcio (see below) will prevent the complete installation of tensorflow.

(This does not happen on TF 1.5, which doesn’t seem to use grpcio)

Source code / logs

Include any logs or source code that would be helpful to diagnose the problem. If including tracebacks, please include the full traceback. Large logs and files should be attached. Try to provide a reproducible test case that is the bare minimum necessary to generate the problem. `MacBook-Pro:grpc feranick$ sudo pip3 install --upgrade tensorflow The directory ‘/Users/feranick/Library/Caches/pip/http’ or its parent directory is not owned by the current user and the cache has been disabled.
