"""
Base class for SharkInference and SharkTrainer
used to execute an mlir_module.
...
Attributes
----------
mlir_module : str
mlir_module represented in string.
function_name : str
function to execute in the given mlir_module.
device : str
device to execute the mlir_module on.
currently supports cpu, cuda, vulkan, and metal backends.
mlir_dialect: str
The dialect in which the given mlir_module is in.
Refer to {https://mlir.llvm.org/docs/Dialects/}
Methods
-------
run(inputs=None):
Runs the mlir_module with the given inputs, if the inputs are not
given it autogenerates the inputs. Also, the inputs should be a
numpy array.
input_info():
Gives the information about the inputs required by the `function_name`.
This can be expensive as it does string matching to do so.
