esmini Function Path Handling and Scenario Class Recognition Issues

[Wankelb]

Hello,

I have encountered some issues while using the scenariogeneration package, specifically with the esmini function and the Scenario class. Here are the details:

Steps to Reproduce

I installed the scenariogeneration package and set up my environment as instructed. Created a Python script to generate a scenario and visualize it using esmini.

import os
from scenariogeneration import xodr, prettyprint, ScenarioGenerator, esmini, Scenario
import numpy as np

class MyScenario(ScenarioGenerator):
    def __init__(self):
        super().__init__()

    def road(self, **kwargs):
        odr = xodr.OpenDrive("myroad")

        # ... (omitting the rest for brevity)

if __name__ == "__main__":
    sce = MyScenario()
    prettyprint(sce.road().get_element())
    sce.generate(".")
    esmini_path = r"C:\Program Files\Tools\esmini\esmini"
    print(f"Using esmini path: {esmini_path}")
    esmini(sce, esminipath=esmini_path, index_to_run='first')

Issues Encountered

Path Handling Issue: When specifying the esmini_path, paths containing spaces (e.g., C:\Program Files\Tools\esmini) result in an error:

The command “C:\Program” is either misspelled or could not be found.

Could you provide guidance on how to handle paths with spaces correctly in this context?

Thank you for your assistance.

thank you.

You found a bug, or at least shortcoming. I see no easy work-around (other than putting esmini in a non-space path). But I prepared a fix. We will discuss internally before merging it. Hopefully it will be included in next release.

Meanwhile if it is urgent, I think you can install the branch: support_spaces_in_paths

1. Move to scenariogeneration root folder
2. Checkout the branch: git checkout support_spaces_in_paths
3. Uninstall any currently installed scenariogeneration: pip uninstall scenariogeneration
4. pip install .

The fix is now merged to main branch and will automatically be included in next release.
