Hi, Can you mention which version you are using ? To start troubleshooting, can you print channel_format before the call of recarray initialisation ?

[found36]

Thanks for your reply.

ok, 2.7.1 It was not clear from me, can you insert 'print(channel_format)' before the line 470 in mdf3reader.py and report here the output ? Reason: a numpy dtype seems not correct, so let's have a look at it, maybe a strange channel name.

it is ok when I reinstall mdfreader 0.2.7 thank you very much.

[ratal]

It means there is potentially regression between 0.2.7 to 2.7.1 ... If you have time to investigate, can I kindly ask you to send this print, otherwise close the issue ?

[(('time_title', u'time'), '<f8'), (('ABS_RRWheelSpeed_title', u'ABS_RRWheelSpeed'), '<u2'), (('ABS_RLWheelSpeed_title', u'ABS_RLWheelSpeed'), '<u2'), (('ABS_FRWheelSpeed_title', u'ABS_FRWheelSpeed'), '<u2'), (('ABS_FLWheelSpeed_title', u'ABS_FLWheelSpeed'), '<u2')]

I coudl notice a regression with python 2.7 and these channel naming issue. I am working on a fix.

[ratal]

I made a fix in last commit only for mdf3 for the moment, you can try it.

If it works for you, please close the issue
