Code snippet

data = MDF(mf4_file) for version 5.20.6 mdf_comman_py :(line 100) : Validate channel selection - version 7.1.1

Traceback

After converting to .exe ,it says the version doesnt support ,armxl and .dbc files for version 7.1.1 : Below : arxml is not supported csv is not supported dbc is not supported dbf is not supported json is not supported ldf is not supported kcd is not supported fibex is not supported sym is not supported xls is not supported xlsx is not supported yaml is not supported scapy is not supported wireshark is not supported odx is not supported

Description

I am unable to load few MF4 files in the asammdf version 5.20.6 ,as it gives the error "To change to a dtype of different size, last axis must be contiguous".Then, I changed asammdf lib version to 7.1.1 ,it gives error that "Multiple occurrences of channel". I changed the above exception to False, and it worked fine in the development mode, but when converted python script to .exe using pyinstaller ,the file doesnt load.

I did that and it worked fine when I ran the script on command prompt. But once I packaged it and ran it as an .exe, it gave me below error and also it said, it doesnt support .arxml and .dbc. arxml is not supported csv is not supported dbc is not supported Then throws below error : asammdf - ERROR - Error during CAN logging processing: Traceback (most recent call last): File "lib\site-packages\asammdf\blocks\mdf_v4.py", line 10480, in process_bus_logging File "lib\site-packages\asammdf\blocks\mdf_v4.py", line 10520, in process_can_logging File "lib\site-packages\asammdf\blocks\utils.py", line 1762, in load_can_database File "lib\site-packages\canmatrix\formats_init.py", line 52, in loads File "lib\site-packages\canmatrix\formats_init.py", line 86, in load KeyError: 'canmatrix.formats.dbc'

[danielhrisca]

have a look at this spec file for guidance https://github.com/danielhrisca/asammdf/blob/development/asammdf.spec

[Rachana-dot]

Yes, its unable to read the value of few signals when loaded but the same file works perfectly with version 5.20.6

what should I understand from this?

[Rachana-dot]

It throws below error: asammdf - ERROR - Error during CAN logging processing: Traceback (most recent call last): File "lib\site-packages\asammdf\blocks\mdf_v4.py", line 10480, in _process_bus_logging File "lib\site-packages\asammdf\blocks\mdf_v4.py", line 10520, in _process_can_logging File "lib\site-packages\asammdf\blocks\utils.py", line 1762, in load_can_database File "lib\site-packages\canmatrix\formats__init.py", line 52, in loads File "lib\site-packages\canmatrix\formats\init__.py", line 86, in load KeyError: 'canmatrix.formats.dbc'

[danielhrisca]

Did you look at the spec file?

[Rachana-dot]

yes!! But the question is, files loads fine in the gui but not while we use the API in the python script

[danielhrisca]

What canmateix version is installed?

[Rachana-dot]

Thank you @danielhrisca ,it got resolved. Canmatrix version was 0.9.5 I built the .exe using a spec file by including all the hidden imports, it resolved the issue.

[jimreb]

@Rachana-dot @danielhrisca How do you managed to resolving it? Could you share the spec file for including the imports?

Thanks!
