when you want to access the header information the call crashes with:

cloud = PyntCloud.from_file(LasFile)
cloud.las_header.offset

Traceback (most recent call last): File "pyncl.py", line 24, in print(cloud.las_header.offset) File "C:\Users\USER\AppData\Local\Continuum\miniconda3\envs\pyntcloud\lib\site-packages\laspy\header.py", line 1135, in get_offset ["x_offset", "y_offset", "z_offset"]]) File "C:\Users\USER\AppData\Local\Continuum\miniconda3\envs\pyntcloud\lib\site-packages\laspy\header.py", line 1134, in return([self.reader.get_header_property(x) for x in File "C:\Users\USER\AppData\Local\Continuum\miniconda3\envs\pyntcloud\lib\site-packages\laspy\base.py", line 742, in get_header_property val = self._get_datum(0, spec) File "C:\Users\USER\AppData\Local\Continuum\miniconda3\envs\pyntcloud\lib\site-packages\laspy\base.py", line 708, in _get_datum data = self._get_raw_datum(rec_offs, spec) File "C:\Users\USER\AppData\Local\Continuum\miniconda3\envs\pyntcloud\lib\site-packages\laspy\base.py", line 703, in _get_raw_datum return(self.data_provider._mmap[(rec_offs + spec.offs):(rec_offs + spec.offs AttributeError: 'NoneType' object has no attribute '_mmap'

Thanks for pointing that out @zwnk . I'll try to find some time to re-focus on laspy integration
