基类：Object

Lightweight NDArray implementation for matx runtime

The structure is currently just a container for a multi-dimensional array, without defining various types of transformations and arithmetic methods. The goal of the structure is to serve as a bridge tool and other machine learning frameworks (pytorch tensorflow) for the conversion of multidimensional arrays

参数:

• arr (List) – Constructing the contents of an NDArray

• shape (List) – Shape of the constructed NDArray

• dtype (str) – The type of the constructed NDArray element, supporting “int32” “int64” “float32” “float64”

Construction method 1

arr is a one-dimensional List, the shape is not empty, producing NDArray with the content of arr and the shape of the given shape

Examples:

>>> import matx
>>> nd = matx.NDArray([1,2,3,4,5,6], [3,2], "int32")
>>> nd
[
 [ 1 2 ]
 [ 3 4 ]
 [ 5 6 ]
]

Construction method 2

arr is a List of arbitrary dimensions, shape is an empty List, producing NDArray with the same shape as arr and the same content as arr

Examples:

>>> import matx
>>> nd = matx.NDArray([[1, 2, 3,], [4, 5, 6]], [], "int32")
>>> nd
[
 [ 1 2 3 ]
 [ 4 5 6 ]
]

>>> nd = matx.NDArray([1, 2, 3, 4, 5, 6], [], "int32")
>>> nd
[1, 2, 3, 4, 5, 6]

Construction method 3

arr is empty, shape is not empty, return a NDArray corresponding to the random initialization content of the shape

class matx.Regex(pattern, ignore_case=False, dotall=False, extended=False, anchored=False, ucp=True)

基类：Object

Regular class implemented using pcre.

参数:

• pattern (str) – Str types. Regular expression pattern.

• ignore_case (bool) – Booleans. Perform case-insensitive matching. The default is false

• dotall (bool) – Booleans. “.” matches any character at all, including the newline. The default is false

• extended (bool) – Booleans. Most white space in the pattern (other than in a character class), and characters between a # outside a character class and the next newline, inclusive, are ignored. An escaping backslash can be used to include a white space or # character as part of the pattern. The default is false.

• anchored (bool) – Booleans. Matches only at the beginning of the subject. The default is false.

• ucp (bool) – Booleans. Sequences such as “d” and “w” use Unicode properties to determine character types, instead of recognizing only characters with codes less than 128 via a lookup table. The default is false.

>>> import matx
>>> regex = matx.Regex("(?<first>.*) are (?<second>.*?) .*")

示例

The following code registers my_packed_func as global function. Note that we simply get it back from global function table to invoke it from python side. However, we can also invoke the same function from C++ backend, or in the compiled TVM code.

targs = (10, 10.0, "hello")
@matx.register_func
def my_packed_func(*args):
    assert(tuple(args) == targs)
    return 10
# Get it out from global function table
f = matx.get_global_func("my_packed_func")
assert isinstance(f, matx.PackedFunc)
y = f(*targs)
assert y == 10

matx.save(jit_module, folder, force_override=False)

matx.script(compiling_obj, *args, backend=None, **kwargs)

Entry function for compiling. Given a python object including function, simple class, compile it to a matx object which mostly keep the behavior of the original python object.

参数:

• compiling_obj (([function, class])) – [input python object to be compiled.]

• args – not used

• backend ([str, None]) – ‘torch’ or ‘pytorch’ or None

• kwargs – keyword arguments passed into different script backend

返回:

obj – the compiled object.

返回类型:

OpKernel

matx.trace(func, *args, **kwargs)

Trace a function and return an executable module that will be optimized using just-in-time compilation.

参数:

• func (callable) – A Python function or a matx Symbol(s) that will be run with args. func arguments and return values must be Operators returned from Script.

• args – func inputs

• kwargs – func inputs

返回:

module – an executable module

返回类型:
