Pythonidle 是否有可能存在 bug？

Question

我正在尝试通过空闲状态使用 neurosynth python 库 对 fMRI 数据数据库运行荟萃分析。当我尝试运行一些最基本的功能时，我收到一个错误，而不是我自己的代码或神经合成器模块中的错误，该错误似乎是空闲本身的错误。

我卸载并重新安装了python 2.7，重新安装了neurosynth及其依赖项，并遇到了相同的错误。我在下面粘贴了我的代码，然后是错误消息，该消息出现在 Unix shell 中（而不是空闲 shell 中）。

有人在使用idle和python 2.7之前遇到过这个错误吗？

剧本：

from neurosynth.base.dataset import Dataset
from neurosynth.analysis import meta, decode, network
import neurosynth

neurosynth.set_logging_level('info')

dataset = Dataset('data/database.txt')
dataset.add_features('data/features.txt')
dataset.save('dataset.pkl')

print 'done'

unix shell 中出现的错误信息：

Idle 用于在 shell 中进行交互式探索、在编辑器中进行编辑以及通过从编辑器运行程序来测试程序。它不适用于程序开发后的生产运行。如果出现问题，应该将 Idle 部分与 running with Python 部分分开。因此，在 unix shell 中，运行

python -m idlelib

（例如）来查看 Idle 是否正确启动。然后，在适当的目录中，运行

python path-to-my-file.py

。哪个不起作用？

错误消息肯定很奇怪，因为它不仅仅是 python 回溯。另一方面，它并不是以一行代码开头。我不知道为什么 select 调用会被中断。
