如何安装pybrain？

Question

我使用git下载了pybrain

$ git clone git://github.com/pybrain/pybrain.git

当我尝试安装时，

$ python setup.py install

安装 scipy 时出错：

Running scipy-0.14.0/setup.py -q bdist_egg --dist-dir /tmp/easy_install-fxe0wp/scipy-0.14.0/egg-dist-tmp-Kbnkhx

ImportError: No module named numpy.distutils.core

我尝试安装其他模块，但遇到了几乎相同的问题。你能解释一下我该如何解决吗？

Answer 1

既然你已经下载了，你也可以使用 pip 进行开发安装

pip install -e /local/path/to/pybrain

这样 pip 可能会为您安装依赖项。

有些系统有非常旧的点子/设置工具，所以你可能需要这样做

pip install --upgrade pip
pip install --upgrade setuptools

如果第一个失败（我在某些系统上见过这种情况），请尝试

python -m pip install --upgrade pip

（您需要对所需安装路径具有写入权限）。

编辑：事实证明这不是简单的安装...我尝试了以下顺序

pip install numpy
pip install scipy
pip install pybrain

在 Ubuntu 12.04 LTS 上的全新 virtualenv 中，scipy 抱怨缺少 BLAS 环境变量...我知道 BLAS 是一个用于统计或数学的库，但仅此而已。

在http://www.scipy.org/install.html 阅读，似乎apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose 可能会安装 scipy（如果您使用的是正确的 Ubuntu 版本——我不是……）

Answer 2

我建议使用 PIP 安装模块 像这样：

pip install pybrain

但如果你不能使用它或选择不使用，请尝试使用@thebjorn's

希望这有帮助，

Answer 3

我不确定，但也许你应该安装 numpy？

pip install numpy

Answer 4

只需使用以下命令从命令行安装：

`pip install pybrain`

Answer 5

你可以下载这个脚本：ez_setup.py

并在 shell $ python ez_setup.py 中运行

您也可以使用easy_install 工具：

$ easy_install scipy
