Lastly, we can find the `.rpm` files in the GBS root directory.
```bash
-$ ls `~/GBS-ROOT/local/repos/tizen/aarch64/RPMS/`
+$ ls ~/GBS-ROOT/local/repos/tizen/aarch64/RPMS/
```
## Ubuntu 16.04 (x86_64)
$ ls /opt/trinity/etc
npu-engine.ini
```
+Note that all logs are printed to the log file specified in `npu-engine.ini` (default: `/tmp/npu-engine.log`).
Then, you can build your application with NPU-Engine library in any convenient way. For example,
```bash
**Ubuntu**: `/opt/trinity/bin`
-## `npu-engine-testdata` package
+## `npu-engine-testdata` package (from [NPU_SystemService_Testdata](https://github.sec.samsung.net/AIP/NPU_SystemService_Testdata))
The `npu-engine-testdata` package contains testdata used in some example test programs.
**FastModel**: `/usr/share/npu-engine/testdata`
## Example: apptest_example_visa
This application ([example_visa.c](/tests/apptests/example_visa.c)) executes NPU models (with single or multi layers) and compares outputs with their golden data.
-Note that the testdata used here follows the NPU binary format ([npubinfmt.h](/include/common/npubinfmt.h)) agreed with several parts.
+Note that the testdata used here follows the NPU binary format ([npubinfmt.h](/include/common/npubinfmt.h)). We currently support two versions of metadata (i.e., npubinfmt_v1 and v2), and older versions could be deprecated soon.
Let's assume you are testing the application in Ubuntu 16.04.
```bash
$ sudo apt-get install npu-engine-example npu-engine-testdata
$ cd /opt/trinity
-$ ./bin/apptests/apptest_example_visa share/npu-engine/testdata/single
+$ ./bin/apptests/apptest_example_visa share/npu-engine/testdata/npubinfmt_v1
...
-$ ./bin/apptests/apptest_example_visa share/npu-engine/testdata/multi
+$ ./bin/apptests/apptest_example_visa share/npu-engine/testdata/npubinfmt_v2
...
```
All tests should be passed if the library is successfully installed.
