Build and Test Instructions

The VPUX NN Compiler is a part of kmb-plugin repository and is built as a part of common build.

It can be enabled in plugin via VPUX_CONFIG_KEY(COMPILER_TYPE) configuration option:

core.LoadNetwork(cnnNet, {{VPUX_CONFIG_KEY(COMPILER_TYPE), VPUX_CONFIG_VALUE(MLIR)}});

If the project is built in developer build mode, the VPUX NN Compiler can also be enabled via IE_VPUX_COMPILER_TYPE=MLIR environment variable.

Unit Tests

The VPUX NN Compiler uses two kind of unit tests:

  • GoogleTest based
  • LLVM LIT based

GoogleTest based Unit Tests

The GoogleTest based unit tests for the VPUX NN Compiler are available in vpuxUnitTests application. It can be used as plain GoogleTest based application (including all command line options) without any specific environment setup. To run only the tests related to VPUX NN Compiler use the following filter: --gtest_filter=*MLIR*.

LLVM LIT based Unit Tests

The LLVM LIT based unit tests use Python scripts to run pattern-match-like tests. This tests requires Python 3.0 to be installed.

The tests are copied to OpenVINO binary directory (<openvino>/bin/<arch>/<build-type>/lit-tests). To run them use the following command:

cd <openvino>/bin/<arch>/<build-type>/lit-tests
python3 lit-tool/lit.py -v VPUX

For native x86 build the LIT tests can also be run via CTest tool:

cd <kmb-plugin-build-dir>
ctest -VV -R LIT-VPUX

Note: In order to run the LIT tests on updated test sources the make all command (or its analogue) must be run prior to copy the updated test sources into OpenVINO binary directory.

Functional tests

Existing functional tests for KMB plugin (vpuxFuncTests) can be used with the VPUX NN Compiler. The supported test cases can be run with the following filter: --gtest_filter=*MLIR*.
