Problem solved ... even as orginally C++ or Java programmer it is strange, but a interpreted language makes it possible to obtain with an import at a different position a complety different behaviour during run-time.
I just putted the import of mathplotlib and pylab after the file reading and after the type conversion and it works. :jumping: Comment to just switch to another system with 64bit. Sometimes if your are not admin of a machine, than it is hard to change the system ;-) Thank you anyhow, based on your comments I found the solution. Do you perhaps know if there is something like a memdefrag :-/?
