我正在尝试安装 pybrains，但出现此错误：

Process finished with exit code 1

在哪里可以找到“结构”模块？

有人遇到同样的问题吗？

我已按照以下说明操作：https://github.com/pybrain/pybrain/wiki/installation。

我错过了什么？

Answer 1

Pybrain 可以通过pip install pybrain 直接设置。

pybrain 中的 FNN 在收敛性和性能上有一点问题。作为替代，Python for AI 上有很多建议，例如 FANN (An example) 和 scikit-learn（用于大量 ML 方法但不直接包含 FNN）。

Answer 2

尽量不要使用pip。我总是更喜欢从 PyPI 或 github（如果可用）获取整个文件夹，然后执行简单的 python setup.py install。

此外，每当您使用正在积极开发（或不常用）的软件包时，请阅读它们的文档。

如果您看到文档：Here。您将看到他们使用 Python 2.x。 而且您显然使用的是 Python 3.x。

获取 Python 2.x 并从 github 下载文件夹。解压并安装。

希望对您有所帮助。

干杯。

Answer 3

尝试以下查询：

1. pip install numpy
2. pip install scipy
3. pip install pybrain

或：

下载ez_setup.py并运行它：

python ez_setup.py

或：

使用easy_install：

easy_install pybrain
