This gist (based on a blog post at byai.io) documents how to set up TensorFlow 1.6 with (e)GPU support without the need to disable SIP. Following the original gist got me a saystem in which training TF on eGPU was successful, but there were various visual glitches due to the newer / less stable version of the driver.
As pointed out by ronchigram, many people are having issues with newer NVIDIA drivers, so it's worth using the nvidia-update script by Benjamin Dobell that installs the latest stable NVIDIA web driver, and if necessary patches it to run on your system. We also don't need to disable SIP when using nvidia-update.
I have also uploaded the wheel files I built to Google Drive. You can skip installing Apple Command-Line-Tools and Bazel and try installing a pre-built wheel - if that fails, try compiling as described below.
- NVIDIA Web-Drivers (387.10.10.10.25.106, the latest stable version at the time of writing)
- CUDA-Drivers
- CUDA 9.1 Toolkit
- cuDNN 7
- Python 2.7 or 3.6
- Apple Command-Line-Tools 8.3.2
- bazel 0.8.1
Note that the install procedure is very sensitive to the specific versions of these packages.
Install the latest stable NVIDIA Web Drivers.
$ bash <(curl -s https://raw.githubusercontent.com/Benjamin-Dobell/nvidia-update/master/nvidia-update.sh)
Check your macOS build version:
$ system_profiler SPSoftwareDataType
Download and install the NVIDIAEGPUSupport that matches your build version from egpu.io. The table lists newer NVIDIA driver versions, but using an older version should also work (in my case using NVIDIA driver version 387.10.10.10.25.106 for nvidia-egpu-v7.zip that is meant for 387.10.10.10.25.158).
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
$ brew install coreutils
Do not install bazel with Homebrew
$ mkdir ~/temp && cd ~/temp
$ curl -L https://github.com/bazelbuild/bazel/releases/download/0.8.1/bazel-0.8.1-installer-darwin-x86_64.sh -o bazel-0.8.1-installer-darwin-x86_64.sh
$ chmod +x bazel-0.8.1-installer-darwin-x86_64.sh
$ ./bazel-0.8.1-installer-darwin-x86_64.sh
Because we need an older version of clang, unfortunately, we have to downgrade to an older version of the Apple Command-Line-Tools.
You can download the older version 8.3.2 directly from the Apple Developer Portal.
$ sudo mv /Library/Developer/CommandLineTools /Library/Developer/CommandLineTools_backup
$ sudo xcode-select --switch /Library/Developer/CommandLineTools
$ vim ~/.bash_profile
# add to .bash_profile

export LD_LIBRARY_PATH=$DYLD_LIBRARY_PATH
$ source ~/.bash_profile
Let`s check if the driver is loaded.
$ kextstat | grep -i cuda

I recommend using pyenv for installing Python. On top of that, I will use pyenv-virtualenv to create a virtual environment for the custom build.
$ brew update
$ brew install pyenv pyenv-virtualenv
# add to bottom of `.bash_profile`
if command -v pyenv 1>/dev/null 2>&1; then
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
fi
$ source .bash_profile
$ pyenv install 3.6.0
$ pyenv install 2.7.0
# create virtualenv
$ pyenv virtualenv 3.6.0 p3gpu
$ pyenv virtualenv 2.7.0 p2gpu
$ git clone https://github.com/tensorflow/tensorflow
$ cd tensorflow
$ git checkout v1.6.0
Unfortunately, with the repo untouched, it will fail to build. Grab the patch for tensorflow 1.6 and apply it.
$ git apply tensorflow_v1.6.0osx.patch
We first compile for Python 3.6. To also install for Python 2.7, run all the following steps, substituting p3gpu with p2gpu.
$ pyenv activate p3gpu
$ pip install six numpy wheel
Compiling TensorFlow can be time-consuming, so it's worth trying a pre-built package first. I have uploaded the wheel files I built to Google Drive, so download the relevant file, activate the relevant Python environment, and
$ pip install /path/to/tensorflow-1.6.0-cp36-cp36m-macosx_10_13_x86_64.whl # Python 3.6
$ pip install /path/to/tensorflow-1.6.0-cp27-cp27m-macosx_10_13_x86_64.whl # Python 2.7
Except CUDA support, CUDA SDK version and Cuda compute capabilities, I left the other settings untouched.

I use iStat Menus to see CPU/GPU utilization. It doesn't report eGPU memory appropriately but GPU processor utilization info is pretty much real-time.

Detailed installation instructions are available at: cuDNN-Installation-Guide.pdf ↩
@chinegro21 you need to run ./configure in the directory you cloned your repository to:
So in the tensorflow directory it should work. Note that it's
./configureand not.configureorconfigure. Justconfiguremight work if.(the current directory) is in yourPATH.Have you tried installing a pre-built pip package instead? Might be easier.
