[Good First Issue]: [OP CONFORMANCE][TEMPLATE] 2 broadcast tests are failed in op conformance

[iefode]

Context

OP conformance suite is validation tool checks a plugin conditions from operation implementation status perspective. OP conformance is based on extracted from OMZ model scope operations and graphs by ov_subgraphs_dumper tool. Extracted graphs are saved as IR (OpenVINO Intermediate representation) and is stored in the public share. OP conformance suite contains the following test types:

• OpImplCheck validates operation support by plugin. Return true or false.
• Inference compare device inference results vs reference over extracted IR as a model. We generate synthetic tensors to get a result. Possible results are passed, failed, hanged (interrupted by timeout), crashed and skipped (just in case -shape_mode is misaligned with graph inputs).
• QueryModel check possibility of graph execution per device. Have the same status as Inference
• ImportExport exports compiled model, imports it and check that models are same. Have the same status as Inference

Template is a simple plugin run inference using reference implementation. It means if we will run conformance over template, we should compare TEMPLATE vs TEMPLATE results. Sometimes we have bugs inside the plugin, reference implementation or test infrastructure leads to negative test result.

What needs to be done?

Description: We have several Broadcast tests failed in operation conformance over TEMPLATE plugin. Do contributor should fix them:

• conformance_Broadcast/ReadIRTest.Inference/Op=Broadcast.3_Type=i64_Shape=dynamic_IR=2058e018d32d8a73b2bf6471186e555c47e2c1a15ceb4131bacc43110bc17d30_Device=TEMPLATE_Config=()
• conformance_Broadcast/ReadIRTest.Inference/Op=Broadcast.3_Type=f32_Shape=dynamic_IR=7562536120d473cca837bb2ad1e3969484868111954ac0b168a5c2805264a689_Device=TEMPLATE_Config=()

How to reproduce:

1. Build the OV using -DENABLE_TESTS=ON -DENABLE_FUNCTIONAL_TESTS=ON
2. Build ov_op_conformance_tests target
3. Run OP conformance to download conformance IRs and run executable file with args:

   python3 /openvino/src/tests/test_utils/functional_test_utils/layer_tests_summary/run_conformance.py -d=TEMPLATE --gtest_filter="conformance_Broadcast/ReadIRTest.Inference/Op=Broadcast.3_Type=f32_Shape=dynamic_IR=7562536120d473cca837bb2ad1e3969484868111954ac0b168a5c2805264a689_Device=TEMPLATE_Config=()"

   NOTE: run_conformance log contains all commands to run ov_op_conformance_tests! You can take them to debug!

4. Check the logs inside working directory and get the results as an example:

   
   [ RUN      ] conformance_Broadcast/ReadIRTest.Inference/Op=Broadcast.3_Type=f32_Shape=dynamic_IR=7562536120d473cca837bb2ad1e3969484868111954ac0b168a5c2805264a689_Device=TEMPLATE_Config=()

5. To debug the test in C++ Use the following command (just an example, refer to note in third item):

openvino/bin/intel64/Release/ov_op_conformance_tests --device=TEMPLATE --input_folders=openvino/src/tests/test_utils/functional_test_utils/layer_tests_summary/temp/models/conformance_ir_files.lst, --report_unique_name --output_folder="openvino/src/tests/test_utils/functional_test_utils/layer_tests_summary/temp/report/parallel" --gtest_filter="conformance_Broadcast/ReadIRTest.Inference/Op=Broadcast.3_Type=f32_Shape=dynamic_IR=7562536120d473cca837bb2ad1e3969484868111954ac0b168a5c2805264a689_Device=TEMPLATE_Config=()" --config_path="" --shape_mode=

>Important NOTE: The issue can be connected with [input generation for Gather Operation](src/tests/functional/shared_test_classes/src/base/utils/generate_inputs.cpp). We should generate input tensor according OV specification!

Hello @K-minutti, are you still working on this?

[K-minutti]

@p-wysocki Hi, yes I'm just starting up is there a deadline in mind? If not I will post an update on progress this weekend.
