Minor modifications to the code

[SebsBarbas]

I added a try ... Except clause because when I ran the: not hasattr() it yielded the following error: "'Key normals not found in TensorMap'". I checked on the internet and could not find a way of solving it.

Also, there was a library missing in the requirements

Thanks a lot @SebsBarbas ! Does this mean that it is failing to compute the normals if they are not available?

Sorry for the late response, I did not see the notification. The issue I had was that for some reason the line

hasattr(self._cloud.point, "normals")

Was throwing an exception error saying that the normals were not there. It is weird as this is exactly what hasattr should be solving, but I had to enclose it in a try except specifically to allow the code to run. Afterwards, the whole thing ran smoothly. If you want to reproduce the error let me know and I will share with you the files I used.
