Topic: ✔ PythonCall: Importing module with submodule


view this post on Zulip Jesper Stemann Andersen (Apr 30 2023 at 08:38):

Using PythonCall, suppose I would like to import a Python module foo and its sub-module bar, where bar defines baz, I would expect the following to work but it does not:

using PythonCall

foo = pyimport("foo")
foo.bar.baz

foo.bar is a Python module (a Py object), but it does not have baz defined - it doesn't seem to have any names defined.

Current workaround seems to be something like:

using PythonCall

foo = pyimport("foo")
foo_bar = pyimport("foo.bar")
foo_bar.baz

julia> using PythonCall

julia> fo = pyimport("fiftyone")
Python module: <module 'fiftyone' from '/Users/jsa/work/julia/FiftyOne.jl/.CondaPkg/env/lib/python3.11/site-packages/fiftyone/__init__.py'>

julia> fo.core
Python module: <module 'fiftyone.core' from '/Users/jsa/work/julia/FiftyOne.jl/.CondaPkg/env/lib/python3.11/site-packages/fiftyone/core/__init__.py'>

julia> fo.core.

No names defined in fo.core, i.e. no completions available in the REPL.

Whereas all the names are defined if importing fiftyone.core separately:

julia> fo_core = pyimport("fiftyone.core")
Python module: <module 'fiftyone.core' from '/Users/jsa/work/julia/FiftyOne.jl/.CondaPkg/env/lib/python3.11/site-packages/fiftyone/core/__init__.py'>

julia> fo_core
Python module: <module 'fiftyone.core' from '/Users/jsa/work/julia/FiftyOne.jl/.CondaPkg/env/lib/python3.11/site-packages/fiftyone/core/__init__.py'>

julia> fo_core.

Seems like the names are indeed there - they are returned by getpropertynames(fo.core) - just that they somehow are not available from the REPL...
