I don't know where the problem is

I solved the problem

pip install liblas The version is wrong!!

so download the whl file，To install http://www.lfd.uci.edu/~gohlke/pythonlibs/#liblas

python install libLAS-1.8.1-cp36-cp36m-win_amd64

Everything is all right ：)

On my OSX 10.13.6., Python 3.6.5, the libLAS version that gets pulled by the Py3DTiles install is version 1.8.1 (for which tests and demos are OK). When you say that the "version is wrong", do you mean that

  1. you previously had another installed version of libLAS (say 1.7.X or 1.8.0) for which it doesn't work ?
  2. the version pulled by default is wrong ?

If this were to be case 2, are you suggesting that the setup.py should require that liblas>=1.8.0 ?

jiawenquan commented 6 years ago

@EricBoix On my Windows 10 .， Python 3.6.2

  1. the version pulled by default is wrong

I think I probably pulled down the 32-bit version But 64-bit version works
