Attributes
|
|
----------
|
|
mlir_module : str
|
|
mlir_module represented in string.
|
|
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(function_name, inputs=None):
|
|
Runs the function with `function_name` within the mlir_module along
|
|
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.
