Hi list I'm packaging a project with pyproject-build-system which follows the src layout in python: (define-public python-cfd-qsense (package (name "python-cfd-qsense") (version "d02178fc02cfef00d7fa0584d552614e9bdf4c5e") (source (origin (method git-fetch) (uri (git-reference (url "https://gitlab.com/hsr-iet/wabesense/cfd_qsense.git") (commit version))) (file-name (git-file-name name version)) (sha256 (base32 "1ys5my2kfsr5w94k619qrdjm5wa7j45z11dw2ib2ha0wpc85aw4x")))) (build-system pyproject-build-system) (arguments `(#:tests? #f ;; error in test suite #:phases (modify-phases %standard-phases (replace 'check (lambda* (#:key tests? #:allow-other-keys) (when tests? (invoke "python" "-m" "unittest"))))))) (propagated-inputs (list python-numpy python-scipy python-matplotlib python-pyaml python-pandas python-numpy-stl python-coolprop)) (home-page "https://gitlab.com/hsr-iet/wabesense/cfd_qsense") (synopsis "CFD simulation tool to produce pressure-discharge curve for water spring taps.") (description "CFD simulation tool to produce pressure-discharge curve for water spring taps.") (license license:gpl3))) When inheriting from this package like so: (package (inherit python-cfd-qsense) (source (local-file %source-dir #:recursive? #t))))) it is no longer importable as module cfd_qsense instead I have to import src.cfd_qsense. Why is this behavior, when using the package as is everything works fine. Thanks for any help.
