compiler.build.PythonPackageOptions

Options for building Python packages

Description

example

opts = compiler.build.PythonPackageOptions(FunctionFiles) creates a PythonPackageOptions object using MATLAB® functions specified by FunctionFiles. Use the PythonPackageOptions object as an input to the compiler.build.pythonPackage function.

example

opts = compiler.build.PythonPackageOptions(FunctionFiles,Name,Value) creates a PythonPackageOptions object with options specified using one or more name-value arguments. Options include the package name, output directory, and additional files to include.

Create a PythonPackageOptions object using file input.

For this example, use the file magicsquare.m located in matlabroot\extern\examples\compiler.

appFile = fullfile(matlabroot,'extern','examples','compiler','magicsquare.m');
opts = compiler.build.PythonPackageOptions(appFile)
opts = 

  PythonPackageOptions with properties:

            FunctionFiles: {'C:\Program Files\MATLAB\R2022b\extern\examples\compiler'}
              PackageName: 'example.magicsquare'
    SampleGenerationFiles: {}
          AdditionalFiles: {}
      AutoDetectDataFiles: on
          SupportPackages: {'autodetect'}
                  Verbose: off
                OutputDir: '.\magicsquarepythonPackage'

You can modify the property values of an existing PythonPackageOptions object using dot notation. For example, enable verbose output.

opts.Verbose = 'on'
opts = 

  PythonPackageOptions with properties:

            FunctionFiles: {'C:\Program Files\MATLAB\R2022b\extern\examples\compiler'}
              PackageName: 'example.magicsquare'
    SampleGenerationFiles: {}
          AdditionalFiles: {}
      AutoDetectDataFiles: on
          SupportPackages: {'autodetect'}
                  Verbose: on
                OutputDir: '.\magicsquarepythonPackage'

Use the PythonPackageOptions object as an input to the compiler.build.pythonPackage function to build a Python® package.

buildResults = compiler.build.pythonPackage(opts);

Create a PythonPackageOptions object and customize it using name-value arguments.

For this example, use the file magicsquare.m located in matlabroot\extern\examples\compiler. Use name-value arguments to specify the output directory and disable automatic detection of data files.

opts = compiler.build.PythonPackageOptions('magicsquare.m',...
    'OutputDir','D:\Documents\MATLAB\work\MagicPythonPackage',...
    'AutoDetectDataFiles','off')
opts = 

  PythonPackageOptions with properties:

            FunctionFiles: {'C:\Program Files\MATLAB\R2022b\extern\examples\compiler'}
              PackageName: 'example.magicsquare'
    SampleGenerationFiles: {}
          AdditionalFiles: {}
      AutoDetectDataFiles: off
          SupportPackages: {'autodetect'}
                  Verbose: off
                OutputDir: 'D:\Documents\MATLAB\work\MagicPythonPackage'

You can modify the property values of an existing PythonPackageOptions object using dot notation. For example, enable verbose output.

opts.Verbose = 'on'
opts = 

  PythonPackageOptions with properties:

            FunctionFiles: {'C:\Program Files\MATLAB\R2022b\extern\examples\compiler'}
              PackageName: 'example.magicsquare'
    SampleGenerationFiles: {}
          AdditionalFiles: {}
      AutoDetectDataFiles: off
          SupportPackages: {'autodetect'}
                  Verbose: on
                OutputDir: 'D:\Documents\MATLAB\work\MagicPythonPackage'

Use the PythonPackageOptions object as an input to the compiler.build.pythonPackage function to build a Python package.

buildResults = compiler.build.pythonPackage(opts);

Input Arguments

collapse all

Files implementing MATLAB functions, specified as a character vector, a string scalar, a string array, or a cell array of character vectors. File paths can be relative to the current working directory or absolute. Files must have a .m extension.

Example: ["myfunc1.m","myfunc2.m"]

Data Types: char | string | cell

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: 'Verbose','on'

Additional files and folders to include in the Python package, specified as a character vector, a string scalar, a string array, or a cell array of character vectors. Paths can be relative to the current working directory or absolute.

Example: 'AdditionalFiles',["myvars.mat","data.txt"]

Data Types: char | string | cell

Flag to automatically include data files, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

  • If you set this property to 'on', then data files that you provide as inputs to certain functions (such as load and fopen) are automatically included in the package.

  • If you set this property to 'off', then you must add data files to the package using the AdditionalFiles option.

Example: 'AutoDetectDataFiles','off'

Data Types: logical

Name of the Python package, specified as a character vector or a string scalar. Specify 'PackageName' as a namespace, which is a period-separated list, such as companyname.groupname.component. The name of the generated package is set to the last entry of the period-separated list. The name must begin with a letter and contain only alphabetic characters and periods.

If not specified, PackageName defaults to the name of the first MATLAB file listed in the FunctionFiles argument.

Example: 'PackageName','mathworks.pythonpackage.mymagic'

Data Types: char | string

MATLAB sample files used to generate sample Python files for functions included with the package, specified as a character vector, a string scalar, a string array, or a cell array of character vectors. Paths can be relative to the current working directory or absolute. Files must have a .m extension.

Example: 'SampleGenerationFiles',["sample1.m","sample2.m"]

Data Types: char | string | cell

Path to the output directory where the build files are saved, specified as a character vector or a string scalar. The path can be relative to the current working directory or absolute.

The default name of the build folder is the package name appended with pythonPackage.

Example: 'OutputDir','D:\Documents\MATLAB\work\mymagicpythonPackage'

Data Types: char | string

Support packages to include, specified as one of the following options:

  • 'autodetect' (default) — The dependency analysis process detects and includes the required support packages automatically.

  • 'none' — No support packages are included. Using this option can cause runtime errors.

  • A string scalar, character vector, or cell array of character vectors — Only the specified support packages are included. To list installed support packages or those used by a specific file, see compiler.codetools.deployableSupportPackages.

Example: 'SupportPackages',{'Deep Learning Toolbox Converter for TensorFlow Models','Deep Learning Toolbox Model for Places365-GoogLeNet Network'}

Data Types: char | string | cell

Flag to control build verbosity, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

  • If you set this property to 'on', then the MATLAB command window displays progress information indicating compiler output during the build process.

  • If you set this property to 'off', then the command window does not display progress information.

Example: 'Verbose','on'

Data Types: logical
