TypeError: data type '<f1' not understood

[morbult]

Hi again Daniel,

I now got a problem with several mdf 4.11 files which I cannot even initialise. They can however be opened with other softwares, at least in ETAS MDA and Vector MDF Validator. In MDF Validator I only get this warning, no XSD files for this MDF version (411), used next matching version 410, but otherwise no problem.

I run asammdf.MDF(file) and get TypeError: data type '<f1' not understood and this traceback

Traceback (most recent call last):

Unfortunately I can't send you a file because I am not able to scramble due to this error.

python=3.7.9
asammdf=5.23.1
numpy=1.19.2

Can you scramble using the code from here ratal/mdfreader#189 (comment)?

[morbult]

I will try but the line copy(name, dst) does not work because copy is undefined. Where does the function come from?

[danielhrisca]

I think it should be shutil.copy

[danielhrisca]

import shutil

[morbult]

Yes I used shutil.copy and sent you the file just now. Thanks!

[danielhrisca]

Should work now with the development branch code. Thank you for the file!

[morbult]

Thanks! I will check later that it works.

When do you think the next version will be released?

[morbult]

Yep, the development branch works so the issue can be closed. Thanks for quick help!
