That doesn't appear to help.

I have instrumented the ‘override_dh_python3’ actions temporarily to
emit the content of the generated ‘requires.txt’ for the package, so it
can be seen in the build output.

The package build run emits this output:

=====
running egg_info
[…]
writing requirements to gandi.cli.egg-info/requires.txt
[…]
make[1]: Entering directory '/<<PKGBUILDDIR>>'
cat gandi.cli.egg-info/requires.txt
IPy
click>=3.1
pyyaml
requests
setuptools

[test]
coverage
nose
tox
dh_python3 \
    --package gandi-cli \
    --requires gandi.cli.egg-info/requires.txt \
    debian/gandi-cli/usr/share/gandi-cli/
[…]
=====

(When I got the name wrong in earlier runs, ‘dh_python3’ emitted a
warning “cannot find requirements file”. So the fact there is no error
above, suggests that in the above run it is reading the correct file.)

Yet the resulting binary package does not contain any of the
corresponding dependencies.

They are all in ‘/usr/share/dh-python/dist/cpython3_fallback’:

=====
$ for dist in setuptools pyyaml click requests IPy ; do grep -i "^$dist\>" /usr/share/dh-python/dist/cpython3_fallback ; done
setuptools python3-pkg-resources
PyYAML python3-yaml
click python3-click
requests python3-requests
IPy python3-ipy
=====

So why is ‘dh_python3’ not adding them to the binary package
dependencies?
