Error: Could not open types-file opendrive_netconvert.typ.xml

[Yupeng-mango]

I want to convert my.xodr to my.net.xml by running python scripts/netconvert_carla.py your_map.xodr -o your_map.net.xml
BUT, there is an error:
Error: Could not open types-file '/home/xxx/OpenCDA/scripts/data/opendrive_netconvert.typ.xml'.
Quitting (on error).
Traceback (most recent call last):
File "scripts/netconvert_carla.py", line 518, in
netconvert_carla(args.xodr_file, args.output, args.guess_tls)
File "scripts/netconvert_carla.py", line 498, in netconvert_carla
_netconvert_carla_impl(xodr_file, output, tmpdir, guess_tls)
File "scripts/netconvert_carla.py", line 371, in _netconvert_carla_impl
raise RuntimeError('There was an error when executing netconvert.')
RuntimeError: There was an error when executing netconvert.

How can I get the file opendrive_netconvert.typ.xml?
Looking forward for your help!
