1. Introduce
It is the Linux AI OP test framework basing on pytest.

2.1 - cases
    It includes case configuration.
    └── ort_ops_model.csv
    For now, it only included onnxruntime-zhouyi operators, case configuration both used in op generate and running.

2.2 - common
    Include utils functions

2.3 - model
    Include all operator models, named in op_input_output.framework. For example, Add_float_float.onnx

2.4 - tests
    Include op generate and op running functions.

3. How to run it
3.1 run all cases
    ./run_pytest_evb.sh all

3.2 run single cases
    ./run_pytest_evb.sh test_onnx_op_001

3.3 regenerate operators
    ./run_pytest_evb.sh gen_ort_ops

3.4 running operators
    ./run_pytest_evb.sh ort_ops


4. How to expand it
4.1 expand onnxruntime operator
    add case configuration in cases/ort_ops_model.csv

4.2 expand new framework operator
    add new case configuration csv in cases
    add new function configuration file in tests
