我正在尝试构建sklearn.tree子包，其中包含一些Cython代码。我在Windows上使用Python 3.6.1和Numpy 1.12.1。
文件setup.py（可以下载here）包含带有代码的distutils配置，例如
config.add_extension("_tree", sources=["_tree.pyx"],...)
所以我希望sources（这个变量翻转下面列出的一长串函数）是一个字符串列表。
但是，在尝试构建软件包时，我会收到下面列出的输出。这意味着source中build_src.py的函数sources是setup.py的元素，不是字符串而是列表。
所以问题是：
C:\Users\ddale\Downloads\scikit-learn-master\sklearn\tree>python setup.py build_ext
Appending tree.tests configuration to tree
Ignoring attempt to set 'name' (from 'tree' to 'tree.tests')

的方式引起的吗？如果是这样，如何改变呢？ sklearn的开发人员是如何使用它的？ const createActions = (function (config, options) {
if (R.isNil(config)) {
throw new Error('an object is required to setup types and creators');
}
if (R.isEmpty(config)) {
throw new Error('empty objects are not supported');
}
return {
Types: convertToTypes(config, options),
Creators: convertToCreators(config, options)
};
})
let results = createActions({
userRequest: ['username'],
userSuccess: ['avatar'],
userFailure: null
}),
Types = results.Types,
Creators = results.Creators;
