Assigns a user module to a Reference associating a new
This module assigns a module
moduleto a Reference
modulecan either be a path to the module file or a module object. In case a module is passed, the source code of the module needs to be retrievable. The source code of the module is then saved as the file specified by
pathwhen the model is saved. A new
ModuleDataobject is created and inserted to the module as
_mx_dataclientattribute. The module associted by this method is not registered in
sys.modules, unless it has been registered beforehand. When the containing model is read back, the module’s name is set to
This method should not be used for modules in the Python standard library or third party packages registered in
sys.modules, such as math, numpy and pandas. For such module, the normal assignment operation should be used, e.g.
space.np = np.
Suppose the following code is saved in “sample.py” in the current directory.
def triple(x) return 3 * x
The code below creates a Reference named “foo” in
>>> space.new_module("foo", "modules/sample.py", "sample.py")
The module becomes accessible as
>>> space.foo <module 'sample' from 'C:\path\to\samplemodule.py'> >>> @mx.defcells(space) ... def bar(y): return foo.triple(y) >>> space.foo.bar(3) 9
modelbe the ultimate parent model of
space. The next code creates a directory named “model” under the current directory, and within the “model” directory, the module is saved as “sample.py” in the “modules” sub-directory of the “model” dir, as specified by the
pathparamter to this method.
str) – Name of the Reference
path – A path to a file to save the module. If a relative path is given, it is relative to the model folder.
module – A path to a module file as a string or path-like object, or a module object.
