Description

hi,

i get the error in the title when i execute

yop = mdfreader.Mdf() yop.read(mf4_path, True, no_data_loading=True)

this error only occurd with the last version of mdfreader the 4.0 i reinstalle the last 3.x version and no more error. i just want to prevent that there is an issue.

you can find the full log error after this:

I do not know how you could install mdfreader version 4.0 but it is not compatible with python2.7 anymore, reason for this major change. If you absolutely want python2.7, you'll have to stick with last 3.x version of mdfreadfer.
