opendrive to commonroad and commonroad to lanelet2 conversion challenge

[nsaberi-geomate]

I am facing challenges in map conversions. When I run the module for # load OpenDRIVE file, parse it, and convert it to a CommonRoad scenario, I get this error:
scenario = opendrive_to_commonroad(input_path)

Traceback (most recent call last):
File “”, line 1, in
File “XXX/commonroad-scenario-designer/crdesigner/map_conversion/map_conversion_interface.py”, line 94, in opendrive_to_commonroad
opendrive = parse_opendrive(input_file)
File “XXX/commonroad-scenario-designer/crdesigner/map_conversion/opendrive/opendrive_parser/parser.py”, line 39, in parse_opendrive
with file_path.open(“r”) as file_in:
AttributeError: ‘str’ object has no attribute ‘open’

I also tried this:

with open(“{}”.format(input_path), “r”) as file_in:
… opendrive = parse_opendrive(etree.parse(file_in).getroot())

But I am getting the same error.

Also tried the GUI version but it gives me no results even on sample files.

It looks like the paths are of wrong type (string instead of pathlib.Path).
The input_path and output_path must be a pathlib.Path object, e.g., as in our example here.

Thanks for your response. Regarding input address, this command worked:

crdesigner --input-file 'adress' --output-file 'address' odrcr

However, for the conversion, I am facing another challenge regarding my opendrive config:

[smaierhofer]

this looks like a bug in the conversion of crosswalks.
A quick-fix could be to comment out the corresponding conversion part (in case you don't need crosswalks).

Can you provide the OpenDRIVE map?
Then, I would create an issue so that we can fix the bug in one of the next releases.

[nsaberi-geomate]

I did comment out line 123, but the same error is produced. Any thoughts? Can you provide your email address, please?

[smaierhofer]

I would try to comment out all calls to this function, i.e., all parts related to crosswalks.

@nsaberi-geomate The problems should be fixed on the develop branch.
