[Bug] Input node value containing "." is incorrectly treated as module.function #176
Description
Hi, when I use following code to run a workflow
from python_workflow_definition.pyiron_base import load_workflow_json
delayed_object_lst = load_workflow_json(file_name='workflow.json')
delayed_object_lst[-1].pull()
For example, the workflow file may contain nodes like this:
[
{"id": 0, "type": "function", "value": "workflow.preprocess"},
{"id": 1, "type": "input", "value": "image.png", "name": "input_image"}
]The value of the nodes are splited by ".", and treat first element as the module
python-workflow-definition/src/python_workflow_definition/pyiron_base.py
Lines 244 to 248 in 4538453
but for input nodes, the value can be a file name, such as "image.png". Because "image.png" contains ., it is interpreted as a Python module path. As a result, the code tries to import image, which raises an error at
