Bug#993622: python3-open3d: Missing dependency on python3-numpy

[Shane Loretz]

Package: python3-open3d
Version: 0.9.0+ds-5+b2
Severity: normal

Dear Maintainer,

It appears python3-open3d is missing a dependency on python3-numpy.
The module can't be imported until it's manually installed.

On a fresh bullseye container I installed python3-open3d 

	bullseye:root> apt install libopen3d-dev/stable libopen3d0d/stable python3-open3d/stable
	Reading package lists... Done
	Building dependency tree... Done
	Reading state information... Done
	Selected version '0.9.0+ds-5+b2' (Debian:11.0/stable [amd64]) for 'libopen3d-dev'
	Selected version '0.9.0+ds-5+b2' (Debian:11.0/stable [amd64]) for 'libopen3d0d'
	Selected version '0.9.0+ds-5+b2' (Debian:11.0/stable [amd64]) for 'python3-open3d'
	...

But I encountered an ImportError:

	>>> import open3d
	Traceback (most recent call last):
	  File "<stdin>", line 1, in <module>
	  File "/usr/lib/python3/dist-packages/open3d/__init__.py", line 3, in <module>
	    from .open3d import *
	ImportError: ModuleNotFoundError: No module named 'numpy'

So I installed python3-numpy, and afterwards I was able to import
open3d.

	>>> import open3d
	>>>

Would you be willing to add this dependency to the Debian package?


Cheers,
Shane
