[Liblas-devel] Problem to import liblas module in Python 2.7

[Howard Butler]

Using laspy should not mean rewriting a ton of scripts. The interface of laspy is almost exactly the same as liblas (on purpose).

The error you are seeing is usually from the DLL being invalid for some reason. Did it get overwritten? Sorry I cannot provide any more information, but I am merely guessing given the error message and knowing nothing about your setup.
