I have the same problem

Did you check if the file is actually generated by the input parameterization code? Maybe you can post the whole output here

I found the problem described above to be just a consequence. The reason was the following:

1. If python 2 and 3 are installed on the computer at the same time, then the scripts called from demo.py start with python 2 and crash.
2. After fixing the problem 1), I found that the method does not work with the new version of open3d. I fixed it by updating the demo.py code.

P.S. I think it is also possible to easily fix the problem of running with tf 2 by importing it in compatibility mode. But haven't tested it yet.

Thank you for the response I will close this issue but feel free to open new ones.
