Test log of installation and running the app in Ubuntu 16.04, Anaconda and Python2.7

[hiankun]

Hi, sorry to post the message here. This would be more like an test log but a clear issue.

I have downloaded the original project and tried to install it in my Anaconda environment (of course it's in Python 2.7). During the installation process, I modified the following two lines in pcloudpy/core/io/converters.py to let the installation went further:

#from vtk.vtkCommonPython import vtkPoints, VTK_UNSIGNED_CHAR
from vtk import vtkPoints, VTK_UNSIGNED_CHAR
#from vtk.vtkFilteringPython import vtkCellArray, vtkPolyData
from vtk import vtkCellArray, vtkPolyData

Then I tried to using conda install and pip install in my Anaconda environment to make the installation successfully. The overall dependencies are list in the end of this post.

I tried to open the GUI app in Python prompt by typing:

import pcloudpy
pcloudpy.gui.app.run()

and the terminal returns:

MultipleInstanceError: Multiple incompatible subclass instances of InProcessInteractiveShell are being created.

with the big logo float in the entire screen as follows:

If I run pcloudpy.gui.app.run() again, the terminal will reply:

     13 def run():
---> 14     app = QApplication(sys.argv)
     15     app.setOrganizationName("pcloudpy")
     16     app.setApplicationName("pcloudpy")

RuntimeError: A QApplication instance already exists.

I also tried to open the GUI app from the source folder by using python main.py. The GUI app will open up without problem, but I tried to open *.ply or *.vtk (I have only these files in hand), the app won't open any thing (with the mouse pointer always be in `waiting state') or crash immediately.

The GUI of the app and the listed functions all look good. I would like to try it more but have no clue to continue.

I don't know whether my test log is helpful for you developers. If you need me to test something more, please let me know.
