PlaidML depends on Bazel v0.9.0 or higher.
bazel build plaidml:wheel plaidml/keras:wheel
sudo pip install -U bazel-bin/plaidml/*whl bazel-bin/plaidml/keras/*whl
The versions of bison and flex that are provided with xcode are too old to build PlaidML. It's easiest to use homebrew to install all the prerequisites:
brew install bazel bison flex
Then, use bazel to build, sepecifying the correct config from tools/bazel.rc:
bazel build plaidml:wheel plaidml/keras:wheel --config macos-10.12
sudo pip install -U bazel-bin/plaidml/*whl bazel-bin/plaidml/keras/*whl
Unit tests are executed through bazel:
bazel test ...
Unit tests for frontends are marked manual and must be executed individually (requires running plaidml-setup prior to execution)
bazel test plaidml/keras:backend_test
