NumpySerializer: NumpySerializer Class

In DyfanJones/sagemaker-r-mlcore: sagemaker machine learning core classes and methods

NumpySerializer Class

Description

Serialize data of various formats to a numpy npy file format. This serializer class uses python numpy package to serialize, R objects through the use of the 'reticulate' package.

Super classes

sagemaker.mlcore::BaseSerializer -> sagemaker.mlcore::SimpleBaseSerializer -> NumpySerializer

Public fields

dtype

The dtype of the data

np

Initialized python numpy package

Methods

Public methods

• NumpySerializer$new()

• NumpySerializer$serialize()

• NumpySerializer$clone()

Inherited methods

• sagemaker.mlcore::BaseSerializer$format()

---

Method new()

Initialize a NumpySerializer instance.

Usage

NumpySerializer$new(dtype = NULL, content_type = "application/x-npy")

Arguments

dtype

(str): The 'dtype' of the data. 'reticulate' auto maps to python, please set R class to be serialized.

content_type

(str): The MIME type to signal to the inference endpoint when sending request data (default: "application/x-npy").

---

Method serialize()

Serialize data to a buffer using the .npy format.

Usage

NumpySerializer$serialize(data)

Arguments

data

(object): Data to be serialized. Can be a NumPy array, list, file, or buffer.

Returns

(raw): A buffer containing data serialized in the .npy format.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

NumpySerializer$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
