Question

我使用MacPorts安装了python27，并将/ opt / local / bin路径添加到PATH变量中。当我执行which python时，我会在/opt/local/bin安装一个，这很好。但是，我使用easy_install安装了nose，而nosetests现在安装在/ usr / local / bin中。在/ opt / local / bin中还有一个nosetests-2.7。我试过运行那个：

/opt/local/bin/nosetests-2.7  --exe sklearn

然而，经过一系列警告和成功的测试后，我最终获得了以下内容：

ERROR: sklearn.cluster.bicluster.tests.test_utils.test_get_submatrix

FAILED (SKIP=16, errors=1)

当我清楚地从/ opt / local / bin目录运行nosetests时，不确定为什么File "/Library/Python/2.7/site-packages/nose-1.3.0-py2.7.egg/nose/case.py"正在被执行。

对此的任何帮助都会非常感激！

更新：

结果：python -c 'import sys; print(sys.path)'

在此特定测试中看起来像数值稳定性问题。除非你特别感兴趣在该平台上使用双聚类模型，否则我不会对此持谨慎态度。

您还可以尝试构建当前的scikit主 - 从git中学习。自上次发布以来，该测试可能已经稳定（虽然我不是100％肯定）。

鼻子python27和sklearn
