Subject: Bug#896274: python3-segyio: segyio fails to import
Package: python3-segyio
Version: 1.5.2-1
Severity: serious
User: helm...@debian.org
Usertags: python-import
After installing python3-segyio importing the module segyio
into a python interpreter fails with the following error:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib/python3/dist-packages/segyio/__init__.py", line 87, in <module>
from .open import open
File "/usr/lib/python3/dist-packages/segyio/open.py", line 1, in <module>
import numpy
ModuleNotFoundError: No module named 'numpy'
The vast majority of import failures is attributed to missing dependencies.
Often times that manifests as an ImportError or ModuleNotFoundError.
Typically, dependencies should be inserted by dh-python via ${python:Depends}
or ${python3:Depends}. Thus a missing dependency can be caused by incomplete
install_requires in setup.py. Sometimes a missing dependency of a dependency
is the cause, in such cases this bug should be reassigned.

I can confirm this and I'm working on a solution. I'm working with my sponsor
and the Debian Science team to address this, and to add an autopkgtest for the
future.
The source is pybuild not detecting the numpy dependency properly, because the
setup.py script is run as a part of a larger cmake project, and it didn't pick
up on the requirements.txt file.
