Using Google Coral in MacOS 10.13.5

Google announced that Coral TPU is now support Mac OS!

Unfortunately, there are several limitations. The official TF lite distribution only supports Mac OS >10.14.

However, the .whl file is just .zip file. so, Download the .whl with proper Python version, unzip and copy them to dist-packages folder just works.

After install edgetpu runtime file, the dylib path modification is required.

install_name_tool -change /opt/local/lib/libusb-1.0.0.dylib /usr/local/lib/libusb-1.0.0.dylib /usr/local/lib/libedgetpu.1.dylib

Also, the latest libusb-1.0.0 should be installed. Below error means libusb is too old to support USB 3.0. Just remove old libusb and install it with homebrew.

Incompatible library version: libedgetpu requires version 3.0.0 or later, but libusb-1.0.0.dylib provides version 2.0.0

Than Works like charm!

It’s really beneficial to test the TFlite model with edge TPU in development system.
