Open3d: Error importing open3d on ubuntu 18.04 (amd64)

[ParikaGoel]

Describe the bug
I am building the open3d from source on my ubuntu 18.04 (amd64) system. It compiles and builds successfully.
Installing C++ library using below commands also runs successfully :
cd build
make install

But when I install python package using "make install-pip-package", it does not work.
In the end, it gives the info "open3d-0.8.0.0-cp36-cp36m-linux_x86_64.whl is not a supported wheel on this platform".
Below I have attached screenshot of the output.

Hi,I face the same problem, I tried install python package through " sudo make python-package" since I used the system’s default Python, and I add " -DPYTHON_EXECUTABLE=/usr/bin/python .." during cmake . I wonder if you have fix this ,thx.

@ParikaGoel Hi! I have run into the same problem recently, the error messages is as below.

At first i was wondering if it's about naming rules of pip, that this .whl has a illegal name so it could not be processed by pip, but i didn't make further attempts about that. Then I managed to solve this problem by manually installing open3d-0.10.1.0-cp37-cp37m-linux_x86_64.whl with pip install ./lib/python_package/pip_package/open3d-0.10.1.0-cp37-cp37m-linux_x86_64.whl. It succeeded and I could import open3d in python shell.

Before doing this I once tried running pip install open3d-0.10.1.0-cp37-cp37m-linux_x86_64.whl and it failed of course, giving the same error message

ERROR: open3d-0.10.1.0-cp37-cp37m-linux_x86_64.whl is not a supported wheel on this platform.

So I'm wondering if this is a naming bug in the make pip-install-packages scripts, making pip try to install open3d-0.10.1.0-cp37-cp37m-linux_x86_64.whl from internet instead of installing the pre-built wheel.

Hoping it helps.
