import mdfreader yop = mdfreader.Mdf('C:\Sunil\mdfDatFiles\RailCPosFaults_5941_14_1_VehMovingDrvlineEngaged.mdf') Also mentioning version of mdf file will be helpful (using mdfvalidator or mdfreader if functional for reading) MDF 3.20

print of issue related variables at the errors location and eventually mdfvalidator screenshots can help troubleshooting complicated issues

ratal commented 5 years ago

Hi, A bit hard to troubleshoot like this but a snapshot of the channel description from MDFValidator could help to understand what goes wrong. Anyway, my guess is that your channel is encoded in 3 bytes for instance (16 < number of bits <=24) but the CFormat expects 4 bytes --> not possible, that is the reason why dataRead cython module is existing. So you should install the wheel (I think only win10 64bit but python 3.7) or compile it on your platform (you need proper environment for python2.7 and win10)

sunlg5 commented 5 years ago

Thank you very much Ratal for your reply I am having lot of signals in MDF file, I am not able to locate channel having 3 bytes. I used PIP install wheel, it showed, "Requirement already satisfied" could you please elaborate more what steps I should take next?

ratal commented 5 years ago

Where your mdfreader is installed, you could try : python setup.py build_ext or the git repo and in the cloned folder : python setup.py develop Maybe errors will appear when you launch those commands, most probably because you do not have installed the right compilation environment -> install it and try again. dataRead module is not used because you have warnings

warn('dataRead crashed, back to python data reading')

As long as you have this, you will face same issue.

sunlg5 commented 5 years ago

Hello Ratal, sorry I was out of office for a two weeks I have installed MinGW as per instructions at: https://cython.readthedocs.io/en/latest/src/tutorial/appendix.html

then I have installed cython and then i downloaded mdfreader-master from github repository and fired on command prompt: python setup.py develop but while installing bitarray its giving exception: Can you please guide me further?? if anything that I am not doing correctly

please refer below command prompt activity log:

Both dataRead and bitarray where not able to compile. I have no experience with mingw. As backup, you could install visual C++ community edition and try to compile for windows. Also according to below link, you might have mixed up 32 and 64 bit python/windows/Mingw. https://forums.x-plane.org/index.php?/forums/topic/118001-error-adding-symbols-helloworld-wont-compile/

Earlier I had installed Visual C++ for python 2.7, still compiling gave issue but now i installed Visual C++ community edition and it compiled well and it did read MDF file well Thank you very much Ratal and I appreciate your help and patience as well

sunlg5 commented 5 years ago

but I have question, how MDFreder setup file decides which compiler to be used for compiling, because while compiling I had both MinGW and Visual C++ community edition compiler on machine?
