I am trying to install a library from the source that makes use of Poetry, but I get this error
error: Multiple top-level packages discovered in a flat-layout: ['tulips', 'fixtures'].
To avoid accidental inclusion of unwanted files or directories,
setuptools will not proceed with this build.
If you are trying to create a single distribution with multiple packages
on purpose, you should not rely on automatic discovery.
Instead, consider the following options:
1. set up custom discovery (`find` directive with `include` or `exclude`)
2. use a `src-layout`
3. explicitly set `py_modules` or `packages` with a list of names
To find more information, look for "package discovery" on setuptools docs
What do I need to do to fix it?

Based on this comment on a GitHub issue, adding the following lines to your pyproject.toml might solve your problem:
[tool.setuptools]
py-modules = []
(For my case, the other workaround provided in that comment, i.e. adding py_modules=[] as a keyword argument to the setup() function in setup.py worked)
Adding the following in pyproject.toml worked for me. It was a repo with many folders but just one folder had the package code:
[tool.setuptools.packages.find]
where = ["."] # list of folders that contain the packages (["."] by default)
include = ["<package name>"] # package names should match these glob patterns (["*"] by default)
exclude = [] # exclude packages matching these glob patterns (empty by default)
namespaces = false # to disable scanning PEP 420 namespaces (true by default)
