Examples can be found on the image-dataset-converter-examples website.
The image-dataset-converter uses the class lister registry provided by the seppl library.
Each module defines a function, typically called list_classes
that returns
a dictionary of names of superclasses associated with a list of modules that
should be scanned for derived classes. Here is an example:
from typing import List, Dict
def list_classes() -> Dict[str, List[str]]:
return {
"seppl.io.Reader": [
"mod.ule1",
"mod.ule2",
],
"seppl.io.Filter": [
"mod.ule3",
"mod.ule4",
],
"seppl.io.Writer": [
"mod.ule5",
],
}
Such a class lister gets referenced in the entry_points
section of the setup.py
file:
entry_points={
"class_lister": [
"unique_string=module_name:function_name",
],
},
:function_name
can be omitted if :list_classes
.
The following environment variables can be used to influence the class listers:
IDC_CLASS_LISTERS
IDC_CLASS_LISTERS_EXCL
Each variable is a comma-separated list of module_name:function_name
, defining the class listers.
