"""Performance benchmark tests for MXNet NDArray Random Sampling Operations.
1. Operators are automatically fetched from MXNet operator registry.
2. Default Inputs are generated. See rules/default_params.py. You can override the default values.

Below 18 random sampling Operators are covered:

['random_exponential', 'random_gamma', 'random_generalized_negative_binomial', 'random_negative_binomial',
'random_normal', 'random_poisson', 'random_randint', 'random_uniform', 'sample_exponential', 'sample_gamma',
'sample_generalized_negative_binomial', 'sample_multinomial', 'sample_negative_binomial', 'sample_normal',
'sample_poisson', 'sample_uniform', 'GridGenerator', 'BilinearSampler']

    Parameters
    ----------
    ctx: mx.ctx
        Context to run benchmarks
    dtype: str, default 'float32'

        Type of Profiler to use (native/python)
    int64_tensor: str, default 'off'
        Input tensor size to use for tests (if on, dimensions >= 2**32)
    warmup: int, default 25
        Number of times to run for warmup
    runs: int, default 100
        Number of runs to capture benchmark results

    Returns
    -------
    Dictionary of results. Key -> Name of the operator, Value -> Benchmark results.
