使用pyproject.toml配置TradingPlatform项目时出现‘package directory 'TradingPlatform' does not exist’错误的求助

Problem #

在运行单元测试时，我尝试从绝对路径导入模块，遇到了如下错误：

tests/unit/test_parameter_combinations.py:3: in <module>
    from TradingPlatform.core.parameter_combinations import ParameterCombinations
E   ModuleNotFoundError: No module named 'TradingPlatform'

ChatGPT建议如果要打包项目，可以创建可编辑安装来解决路径问题，而我之后也打算发布这个项目，所以我创建了如下toml文件：

[build-system]
requires = ["setuptools>=64", "wheel"]
build-backend = "setuptools.build_meta"

[project]
name = "TradingPlatform"
version = "0.1.0"
description = "A platform for trading infrastructure and strategy testing."
dependencies = [
    "pandas",
    "numpy",
    "scikit-learn",
    "statsmodels",
]

[tool.setuptools]
packages = ["TradingPlatform"]

[tools.setuptools.packages.find]
where = ["."]
include = ["TradingPlatform*"]

这是简化后的项目目录结构（我移除了core和tests里的部分模块来精简展示）：

TradingPlatform
├── __init__.py
├── core
│   ├── __init__.py
│   ├── base_trading_strategy.py
├── notebooks
│   └── main.ipynb
├── pyproject.toml
├── tests
│   ├── integration
│   │   └── __init__.py
│   └── unit
│       ├── __init__.py
│       └── test_strategy_performance_evaluation.py
└── utils
    ├── __init__.py
    ├── helper_funcs.py
    └── logging_setup.py

但现在我遇到了错误：error: package directory 'TradingPlatform' does not exist。

What I Have Tried #

我被这个错误困扰了很久，尝试过重新配置toml文件、卸载并重新安装包，但都没用。以下是我尝试过的几种toml配置：

[tool.setuptools]
packages = ["TradingPlatform", "TradingPlatform.core", "TradingPlatform.utils", "TradingPlatform.tests"]

[tool.setuptools.package-dir]
# Explicitly tell setuptools where to find the root package directory
TradingPlatform = "TradingPlatform"

[tool.setuptools]
packages = ["TradingPlatform", "TradingPlatform.core", "TradingPlatform.utils", "TradingPlatform.tests"]

[tool.setuptools.packages.find]
where = ["."]

我原本期望在.egg-info目录下的top_level.txt文件中能找到目录名TradingPlatform以及各个子模块：

core
tests
utils

但实际上文件里只有TradingPlatform，有时候甚至是空的。

我对打包发布项目不太熟悉，非常希望能得到解决这个问题的指导。如果需要更多细节，请告诉我。
